MEDIUM INFUSION EPOXY – A-298/B-225 Medium Infusion Epoxy is a two-component, very low viscosity system developed specifically for use in resin infusion and VARTM processes. Medium Infusion Epoxy was formulated to provide for rapid saturation of carbon fiber laminate, fiberglass, and Kevlar. Processability parameters are enhanced due to Medium Infusion Epoxy’s low mixed viscosity and wet-out potential. This system is not designed to be used in open mold applications. STORAGE INFORMATION The storage temperature of Medium Infusion Epoxy will greatly affect the ease of mixing, application and, curing time. For best results, Medium Infusion Epoxy should be stored at (60-80 °F or 16-27 °C) for at least 24 hours before use. MIXING INFORMATION Mix RESIN WITH (hardener) for 3 minutes using a Jiffy Mixer and a slow speed drill. Mix at slow speed (less than 500 rpm) to avoid air entrainment. When adding part B to part A, be sure to scrape the sides of the hardener (part B) container in order to remove all of the hardener. This is essential to maintain proper mix ratio. DO NOT mix more material than can be used within the stated working time. REMEMBER - you will have less working time at higher temperatures. CRYSTALLIZATION INFORMATION Crystallization of epoxy resin is not an uncommon occurrence; in some cases, it is simply a reflection of the high-performance nature of the material. Under the perfect conditions, usually extreme temperature change, any epoxy resin can crystalize. The crystallization may present itself as the resin becoming cloudy all the way to the resin turning to a solid. Follow the following steps to restore a crystallized epoxy resin to its normal state: 1) Place resin container in warm water until the resin reaches approximately 120-degrees Fahrenheit. (An easy way to achieve this with normal household products is a crockpot) 2) Keep epoxy resin at this temperature for several hours. Mixing may be needed while warm to dissolve all crystals. 3) Allow the epoxy resin to cool back down to room temperature before use. The resin being warm can drastically change working times. 4) Feel free to use this epoxy resin just as you normally would. Click this link for technical specs.
