METLAB EPOXY is a low viscosity, two component clear casting resin. METLAB gels rapidly at room temperature and cures to a clear tough chemical resistant compound. It has excellent adhesion to most substrates as well as a good electrical insulator. Uses include encapsulating, potting metallographic or similar specimens, and potting as electronic devises. Mix 15 parts (by volume) of METLAB resin with 2 parts (by volume) of METLAB hardener. A 100 gram mass will gel in 20 min. at 23 degrees C. Cure time will depend on temperature and mass of the resin. 4-8 hours at room temperature is usually sufficient. Can be used with vacuum impregnation. Shore D hardness of 82
