Description
MAX GRE A/B is a two part hybrid-epoxy based resin system (Bisphenol A / Bisphenol F/ Novalac epoxy resin) formulated for gasoline resistance and other solvents of the same nature. It can be used as an impregnating resin for fiberglass, carbon fiber and other fabrics for fabricating composite fuel cells and tanks. MAX GRE A/B is resistant to sudden mechanical impact, cryogenic temperatures and resistant in electrostatic build up (triboelectric series or mechanical rubbing).
It can be used as a coating for metals, wood, concrete and other substrates to provide a high degree of chemical resistant barrier against petroleum solvents and liquid fuels. MAX GRE A/B can also be used as an adhesive for bonding composite structures that may come in contact with gasoline and other types of solvents and fuel compounds.
