Unit Size Net Weight Pint 1 lb Gallon 9 lb Five Gallon 45 lb Flexer Epoxy Flexibilizer is a clear, low viscosity liquid additive that will lower the durometer (Shore hardness) of some Smooth-On casting and laminating epoxies. When added to the epoxy system in the proper proportion, the cured epoxy will be softer and, in some cases, can be made semi-rigid. Flexer will lower the viscosity of the epoxy system, improves wetting capability through composite reinforcements (fiberglass cloth Kevlar, etc.) for laminating and filler load capacity.
