Description
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 while also allowing for maximum open time. 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.

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. 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 entrapment. 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
SAFETY PRECAUTIONS
Avoid breathing of vapors. Forced local exhaust is recommended to effectively minimize exposure. NIOSH approved, organic vapor respirators and forced exhaust are recommended in confined areas, or when conditions (such as heated polymers, sanding) may cause high vapor concentrations. DO NOT WELD ON, BURN OR TORCH ON OR NEAR, ANY EPOXY MATERIAL. HAZARDOUS VAPOR IS RELEASED WHEN AN EPOXY IS BURNED.
