Flexible Epoxy Resin

New EP40 flexible, two-component epoxy resin features high shear and peel strength.

EP40 adheres to substrates ranging from engineering plastics such as polycarbonates, acrylics, and ABS to steel, aluminum, and other metals. Shear and peel strengths for bonding polycarbonates are about 1,000 psi and 20 pli, respectively, while steel and aluminum bonds yield shear strength as high as 1,800 and 1,500 psi. Temperature range is –100 to 230°F. The product also resists thermal cycling and mechanical vibration and shock. Electrical insulation properties are excellent, even after prolonged exposure to hostile environmental conditions. The compound cures readily at ambient or more quickly at elevated temperatures.
