Proper Usage Data And Other Detailed Information Are Posted At This Page. Mix the Resin And Curing Agent Only After The Surface Is Prepared For Application. Finally, Ensure The Application Must Be Fully Cured Before Use In Any Application, Especially For Food Contact Application.STEP 1. SURFACE PREPARATIONThe quality of adhesion of any coating or adhesive application is dependent on how well the surface is prepared. The resin system must be able to properly ‘wet-out’ the surface to form a continuous film. Surfaces demonstrating poor wettability prevents the liquid resin from forming a cohesive bond.It is highly recommended that the MAX CLR comes in direct contact with the base substrate to achieve the best performance. Application of MAX CLR over an existing coating limits the adhesion performance of the MAX CLR of the coating it is applied to.Improper surface wetting yields poor coating application(crawling) and cured adhesion that will delaminate during use.POOR WETTING OF THE RESIN (CRAWLING) DUE TO OIL-BASED STAIN APPLIED ON WOOD This hydrophobic characteristic is commonly seen in nature when leaves repel water that keeps the surface dry. It limits the interaction between liquids and solids.Wetting is the ability of a liquid to interfaces or wet-out a solid surface. Its dynamics is expressed as surface tension. A surface that demonstrates low surface tension, such as waxed surface, oily surface or slick plastics like Teflon will prevent the liquid resin to wet-out and cause poor adhesion. In the same respect, if the surface is coated from a previous application, the epoxy adhesion is limited to adhesion quality of the coating is applied over. Make sure to remove any loose or peeling old coating before application to avoid delamination. If possible remove the old coating by mechanical sanding or power washing so the applied epoxy is in direct contact with the base substrate. Applying a coating over oil-based stain should be avoided.

Paste link into a browser window:The Following Surface Preparation Procedures Are Recommended. METALS AND CONCRETEDegrease Metals– Wipe surface with a lint-free rag dampened with Methyl Ethyl Ketone (MEK) or acetone to remove all oil, dirt, and grease. Degrease Concrete- Use 2 cups of TSP (trisodium phosphate) detergent per 5 gallons of hot water and scrub with a stiff deck brush. Rinse with water and allow to dry.Etch Metals – For optimum results, metal parts should be immersed in a chromic acid bath solution consisting of: Sodium Dichromate4 Parts By WeightSulfuric Acid10 Parts By WeightWater30 Parts By Weight The solution is held at 160°F (71°C), and the parts left immersed for 5 to 7 minutes. Rinse – remove metal parts from etching bath and rinse with clean water. (distilled water is recommended).Etch Concrete- Use commercially sold concrete etching solution (hydrochloric acid based works best). Neutralized per instructions, rinse and allow to dry thoroughly.ALTERNATE PROCEDURE Degrease, scour and dry – Often etching as outlined above is not practical. The metal surfaces may be cleaned by degreasing as noted above, scouring with an alkaline cleanser followed by rinsing and drying.Degrease and dry – Degrease the surface as noted above, sand or sandblast the surface lightly but thoroughly. Rinse with acetone or Methyl Ethyl Ketone (MEK), and dry.GLASSDegrease – With MEK as above, or with a strong boiling solution of a good grade household detergent.Etch – For optimum results, degreasing can be followed by the chromic acid bath outlined above.WOODSand – Bonding surfaces should be sanded lightly, but thoroughly to remove all external contamination.Clean – Carefully remove all dust, or particles of wood from sanded areas. A stiff and clean brush or compressed air can be used.PLASTICClean – Remove all dirt, oil, or other surfaces contaminated with detergent soap or degreasing solvent and water, followed by thorough rinsing and drying. A solvent that does not have a detrimental effect may also be used.Sand – Surfaces to be bonded should be sanded lightly, but thoroughly to remove surface sheen.Clean – Carefully remove all dust or particles of plastic from the sanded area. A clean brush, lint-free cloth, or compressed air may be used.STEP 2. CHECK THE PART A OR RESIN BOTTLE FOR CRYSTALLIZATIONCOLD WEATHER NOTICERESIN CRYSTALLIZATION FROM COLD TEMPERATURE EXPOSUREOR AFTER PROLONGED STORAGE This Is The Common Cause Of Poor Cured Results During The Winter Season The resin component or PART A may crystallize due to cold temperature exposure or after being stored. This resin system was developed for high strength applications and other mandatory applications.It is of a high purity grade that makes it prone to crystallization. Similar to high purity compounds like honey that freezes when placed in cold temperature like the refrigerator (below 50ºF or 10ºC); high purity epoxy resins freeze or crystallize below 57°F.All kits are heat-processed before packaging to ensure PART A is in its liquid form. Please inspect the resin component for any solidified crystals, which will appear as waxy solid or cloudiness on the bottom of the PART A bottle.To ensure a trouble-free cure, heat-process the PART A bottle, especially for pigmented resin systems and destinations where the cold temperature is expected.Crystallization also occurs if the kit has been stored over the winter months.Please inspect the resin component for any solidified crystals, which will appear as waxy solid or cloudiness on the bottom of the PART A bottle. All kits are heat-processed before shipping to ensure PART A is in its liquid form. However, during the winter months the kit may be exposed to cold temperature during shipping. Store the kit above 65°F with caps securely in place and the kit will remain viable for up to 3 years or longer and prevent crystallization.Visit this link for more details:https://www.youtube.com/watch?v=x31gkzdZkiI&list=PL6x6YfnNMffz_q_ZdTRPDjhjFtkVeZZufCut And Paste To A New Browser.New eBay Guidelines Does Not Allow Direct Links Outside eBay EnvironmentOREnter This Search Phrase On YouTube.Com To View Our Video Tutorial PlaylistMAX EPOXY RESIN – The Epoxy Experts Video Tutorials How To Use And Apply Any Epoxy Resin SystemDO NOT USE UNLESS PROCESSED TO REVERT ANY CRYSTALLIZED RESIN BACK TO A LIQUID STATE AND AVOID POOR CURED RESULTS.

Blending amounts greater than 1000.0 grams or 1 quart in volume requires careful attention to ensure the mixed amount is used within the established working time to prevent exothermic “run-away” reaction. Do not let the mixed resin to sit in mass greater than 10 minutes. The heat generated during polymerization accelerates the chemical reaction and cause a ‘run-away’ reaction to occur. The mixture can generate temperatures above 300°F and cause an uncontrollable chemical reaction.BASIC EPOXY RESIN USAGE AVOIDING EXOTHERMIC RUN AWAY REACTION – YouTubeVideo will open in a new window Using the eBay App?

Mix a batch of the MAX CLR and apply (brush, roller or squeegee) the mixed coating onto the substrate first. Allow the first application to impregnate and absorb into the porosity and allow to cure until it has set dry to the touch for 8 to 12 hours. The first application seals the surface porosity and prevents further resin absorption and eliminate air bubbles from outgassing from the surface. STEP 4. MIXING PROCEDUREThe two components must be mixed thoroughly to eliminate problems such as tacky or uncured spots. Use the “two container method” as demonstrated in this video demonstration, which ensures a homogeneous mixture of the resin and curing agent.

APPLICATION DEMONSTRATIONSCondition the ambient temperature to 75°F for best results. Ensure that the work area is dust free and well ventilated. MAX CLR is self-leveling and will continue to flow until it polymerization converts it to a solid phase. It can be applied by using a bristle or high-density foam brush/roller or poured into place. MAX CLR is self-leveling, ensure the surface is level and secure any leaks by using tape to create a temporary patch and prevent leakage.When sealing wood substrates, the first application causes ‘grain-raising’ to occur. Apply a thin coat over the bare wood and allow the coating to seal the porosity and prevent bubbles to occur from further outgassing. For most wood materials, ‘grain raising’ will occur.Allow the MAX CLR to cure for 12 hours. For wood substrates, lightly sand the surface with fine sandpaper (180 grit) to remove the grain raising. Apply the another coat over the previous coat to a smooth surface that will serve as the final top coat.What Is ‘Grain Raising’?When a liquid coating is applied over wood, fibers will begin to swell, and this will produce ‘grain raising’ to occur.Raised grains are small end fibers protruding from the coating causing unsightly unevenness. Allow the applied resin to cure and lightly sand the surface using fine-grit sandpaper. Remove dust and debris by wiping with a lint-free rag dampened with alcohol or acetone and allow to dry. Once the surface is prepared, apply the second coat of MAX CLR which will yield a smooth blemish free coating.

CURINGTo achieve the best cure results, the ambient condition should be between 75°F to 85°F and the relative humidity is below 80%.The colder the temperature the longer takes to fully cure. Use an infrared lamp to warm the ambient temperature. Infrared lamps also work well for warming large work areas.Although we have formulated all of our MAX EPOXY RESIN SYSTEM product line to be resistant to amine-blush, it is recommended not to mix any resin systems in high humidity conditions, greater than 60%. Always make sure that the substrate or material the epoxy resin system is being applied to is well prepared as possible to ensure the best-cured performance. Always review the published data and information for proper usage, application, and general safety information. Our expert staff of engineers is available for consultation and application assistance. Allow the lay-up to cure for a minimum of 24 to 36 hours before handling.Optimum cured properties can take up to 7 days depending on the ambient cure condition. The ideal temperature cure condition of most room temperature epoxy resin is 75°F to 85°F at 20% relative humidity.Higher curing temperatures will promote faster polymerization and development of cured mechanical properties.

This method is also defined as a SYNERGISTIC COMPOSITION. COMPOSITE MATERIAL COMPOSITIONREINFORCING FABRIC & IMPREGNATING RESIN PLUS ‘ENGINEERED PROCESS’ EQUALS COMPOSITE LAMINATE WITH THE BEST WEIGHT TO STRENGTH PERFORMANCE With respect to the raw materials selection -fabric and resin, the fabricating process and the and curing and test validation of composite part, these aspects must be carefully considered and in the engineering phase of the composite. Step One: Fabric SelectionTYPES OF FABRIC WEAVE STYLE AND SURFACE FINISHING FOR RESIN TYPE COMPATIBILITYFabrics are generally considered ”balanced” if the breaking strength is within 15% warp to fill and are best in bias applications on lightweight structures.“Unbalanced” fabrics are excellent when a greater load is required one direction and a lesser load in the perpendicular direction. Tow: The bundle of individual carbon filaments used to weave carbon fabric. 50k tow means there are 48-50,000 carbon filaments in the tow. Smaller tow i.e. 12k, 6k, 3k, and 1k are obtained by dividing the 50k tow into smaller bundles.Thread Count: The number of threads (tow in carbon and yarn in Aramid) per inch. The first number will be the warp count and the second will be the fill count.Fill: The threads that run the width of the roll or bolt and perpendicular to the warp threads.Warp: The threads that run the length of the roll or bolt and perpendicular to the fill threads.Finish: The chemical treatment to fiberglass making it compatible with resin systems, therefore improving the bond between the fiber and the resin.Finishing fiberglass typically decreases the fiber strength by as much as 50%. Both Silane and Volan finishes are epoxy compatible. Historically, Volan has been considered a softer finish for a more pliable fabric, but recent advances have yielded some excellent soft Silane finishes.Thickness: Measured in fractions of an inch. The thicker the fabric the more resin required to fill the weave to obtain a surface-smooth finished part.Weaves:Plain weave means the warp and fill threads cross alternately. This is the most common weave.4 Harness (4 HS Satin or crowfoot) weave means the fill thread floats over three warp threads, then under one warp thread. This weave is more pliable than the plain weave, therefore conforms to complex curves more easily.8 Harness (8 HS Satin) weave means the fill thread floats over seven warp threads, then under one warp thread. This weave is the most pliable of the standard fiberglass weaves.2 x 2 Twill weave means the fill thread floats over two warp threads, then fewer than two warp threads. This weave is found most commonly in carbon fabrics and is more pliable than plain weave.Most fabrics are stronger in the warp than the fill because higher tension is placed on the warp fiber keeping it straighter during the weaving process. Rare exceptions occur when a larger, therefore stronger thread is used in the fill direction than the warp direction. PLAIN WEAVEIs a very simple weave pattern and the most common style. The warp and fill yarns are interlaced over and under each other in alternating fashion. Plain weave provides good stability, porosity and the least yarn slippage for a given yarn count. 8 HARNESS SATIN WEAVEThe eight-harness satin is similar to the four-harness satin except that one filling yarn floats over seven warp yarns and under one.This is a very pliable weave and is used for forming over curved surfaces. 4 HARNESS SATIN WEAVEThe four-harness satin weave is more pliable than the plain weave and is easier to conform to curved surfaces typical in reinforced plastics. In this weave pattern, there is a three by one interfacing where a filling yarn floats over three warp yarns and under one. 2×2 TWILL WEAVETwill weave is more pliable than the plain weave and has better drivability while maintaining more fabric stability than a four or eight harness satin weave. The weave pattern is characterized by a diagonal rib created by one warp yarn floating over at least two filling yarns. SATIN WEAVE TYPE CONFORMITY UNTO CURVED SHAPES Plain Weaves, Bi-axial, Unidirectional Styles For Directional High Strength Parts Use this weave style cloth when high strength parts are desired.It is ideal for reinforcement, mold making, aircraft and auto parts tooling, marine, and other composite lightweight applications.7544 Fiberglass – YouTube FIBERGLASS FINISHING FOR RESIN COMPATIBILITYAll of the fiberglass fabrics is woven By HEXCEL COMPOSITES, a leading manufacturer of composite materials engineered for high-performance applications in marine, aerospace for commercial and military, automotive, sporting goods and other application-critical performance.

Adding more curing agent than the recommended mix ratio will not promote a faster cure. Over saturation or starving the fiberglass or any composite fabric will yield poor mechanical performance. When mechanical load or pressure is applied to the composite laminate, the physical strength of the fabric should bear the stress and not the resin. If the laminate is over saturated with the resin it will most likely to fracture or shatter instead of rebounding and resist damage.Don’t how much resin to use to go with the fiberglass?A good rule of thumb is to maintain a minimum of 30 to 35% resin content by weight, this is the optimum ratio used in high-performance prepreg (or pre-impregnated fabrics) typically used in aerospace and high-performance structural application.For general hand lay-ups, calculate using 60% fabric weight to 40% resin weight as a safety factor. This will ensure that the fabricated laminate will be below 40% resin content depending on the waste factor accrued during fabrication.Place the entire pre-cut fiberglass to be used on a digital scale to determine the fabric to resin weight ratio. Measuring by weight will ensure accurate composite fabrication and repeatability, rather than using OSY data.THE USE OF A WEIGHING SCALE IS HIGHLY RECOMMENDED Purchase this scale with any of our product offering and the shipping cost of the scale is free. https://www.ebay.com/itm/222630300203A good rule of thumb is to maintain a minimum of 30 to 35% resin content by weight, this is the optimum ratio used in high-performance prepreg (or pre-impregnated fabrics) typically used in aerospace and high-performance structural application.

By laying the fiberglass onto a layer of the prepared resin, fewer air bubbles are entrapped during the wetting-out stage. Air is pushed up and outwards instead of forcing the resin through the fabric which will entrap air bubbles. This technique will displace air pockets unhindered and uniformly disperse the impregnating resin throughout the fiberglass.HAND LAY-UP TECHNIQUE Eliminating air entrapment or void porosity in an epoxy/fiberglass lay-up processFiberglass Hand Lay Up For Canoe and Kayak Building- Cedar Strip Kayak Fiberglassing – YouTubeVideo will open in a new windowBasic Hand Lay-up FiberglassingVideo will open in a new windowVACUUM BAGGING PROCESS For performance critical application used in aerospace vehicles, composite framing for automotive vehicles and marine vessels, a process called ‘Vacuum Bagging’ is employed to ensure the complete consolidation of every layer of fabric. The entire tooling and lay-up are encased in an airtight envelope or bagging and a high-efficiency vacuum pump is used to draw out the air within the vacuum bag to create negative atmospheric pressure. Once a full vacuum (29.9 Inches of Mercury) is achieved, the negative pressure applies a compacting force of 14.4 pounds per square inch (maximum vacuum pressure at sea level) is applied to the vacuum bag transferring the force to the entire surface area of the laminate. Vacuum pressure is maintained until the resin cures to a solid. For room temperature curing resin system, the vacuum pump is left in operation for a minimum of 18 hours. External heat can be applied to the entire lay-up, thus accelerating the cure of the resin system. The vacuum force also removes any entrapped air bubble between the layers of fabric and eliminate what is called, porosity or air voids. Porosity within a laminate creates weak spots in the structure that can be the source of mechanical failure when force or load is applied to the laminate. The standard atmosphere (symbol: atm) is a unit of pressure defined as 101325 Pa (1.01325 bar), equivalent to 760 mm Mercury or 29.92 inches Mercury or14.696 pounds per square inch of pressure.FiberglaSs And Carbon Fiber Vacuum Bagging and Flat Panel Laminate – YouTubeVideo will open in a new window AUTOCLAVE CURING PROCESS BASIC OPERATION OF THE AUTOCLAVE PROCESS In the autoclave process, high pressure and heat are applied to the part through the autoclave atmosphere, with a vacuum bag used to apply additional pressure and protect the laminate from the autoclave gases. The cure cycle for a specific application is usually determined empirically and, as a result, several cure cycles may be developed for a single material system, to account for differences in laminate thickness or to optimize particular properties in the cured part. The typical autoclave cure cycle is a two-step process. First, vacuum and pressure are applied while the temperature is ramped up to an intermediate level and held there for a short period of time. The heat reduces the resin viscosity, allowing it to flow and making it easier for trapped air and volatiles to escape. The resin also begins wetting the fibers at this stage.In the second ramp up, the temperature is raised to the final cure temperature and held for a sufficient length of time to complete the cure reaction. During this step, the viscosity continues to drop, but preset temperature ramp rates and hold times then stabilize viscosity at a level that permits adequate consolidation and fiber wetting, while avoiding excessive flow and subsequent resin starvation. These control factors also slow the reaction rate, which prevents excessive heat generation from the exothermic polymerization process. Upon completion, the cured mechanical performance of the composite is often much stronger and lighter compared to a hand lay-up, or vacuum bagged composite laminate. VACUUM INFUSION PROCESSVacuum Infusion Process is also known in the composites industry as Vacuum Assisted Resin Transfer Molding or VARTM.Similar to the Vacuum Bagging Process where the negative pressure is used to apply consolidation force to the laminate while the resin cures, the resin is infused into the fabric lay-up by sucking the impregnating resin and thus forming the composite laminate.The VARTM Process produces parts that require less secondary steps, such as trimming, polishing or grinding with excellent mechanical properties. However, vacuum infusion requires more additional or supplemental related equipment and expendable materials. So the pros and cons of each presented composite fabrication process should be carefully determined to suit the user’s capabilities and needs.Please view the following video demonstration which explains the process of Vacuum Infusion or VARTM process.MAX 1618 A/B VACUUM ASSISTED RESIN TRANSFER MOLDING PROCESSCARBON FIBER VACUUM INFUSION WITH EPOXY RESIN – VACUUM BAGGING WITH MAX 1618 EPOXY RESIN – YouTubeVideo will open in a new windowStep Four: Proper CuringAlthough we have formulated all of ur MAX EPOXY RESIN SYSTEM product line to be resistant to amine-blush, it is recommended not to mix any resin systems in high humidity conditions, greater than 60%. Always make sure that the substrate or material the epoxy resin system is being applied to is well prepared as possible to ensure the best-cured performance. Always review the published data and information for proper usage, application, and general safety information. Our expert staff of engineers is always available for consultation and assistance. Allow the lay-up to cure for a minimum of 24 to 36 hours before handling. Optimum cured properties can take up to 7 days depending on the ambient cure condition. The ideal temperature cure condition of most room temperature epoxy resin is 22 to 27 degrees Celsius at 20% relative humidity. Higher ambient curing temperatures will promote faster polymerization and development of cured mechanical properties. Improving mechanical performance via post heat cure A short heat post cure will further improve the mechanical performance of most epoxy resins. Allow the applied resin system to cure at room temperature until for 18 to 24 hours and if possible, expose heat cure it in an oven or other sources of radiant heat (220°F to 250°F) for 45 minute to an hour. You can also expose it to direct sunlight but place a dark colored cover, such as a tarp or cardboard to protect it from ultraviolet exposure. In general room temperature cured epoxy resin has a maximum operating temperature of 160°F or lower. A short heat post cure will ensure that the mixed epoxy system is fully cured, especially for room temperature cure system that can take up to 7 days to achieve 100% cure. Some darkening or yellowing of the epoxy resin may occur if overexposed to high temperature (>250 F). AMINE BLUSHThe affinity of an amine compound (curing agent) to moisture and carbon dioxide creates a carbonate compound and forms what is called amine blush. Amine blush is a wax-like layer that forms as most epoxies cure. If the epoxy system is cured in extreme humidity (>70%).It will be seen as a white and waxy layer that must be removed by physical sanding of the surface followed by an acetone wipe.

The container must withstand the tenacity of the chemical and must be free of contamination. Most epoxy curing agent has a degree of corrosivity, as a general practice, protective gloves should be worn when handling chemicals of the same nature.
