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 semirigid. Flexer® will lower the viscosity of the epoxy system, improves wetting capability (for laminating) and filler load capacity.
Make Epoxy Semi-rigid - make pieces that are less brittle with increased impact resistance.
Choose Desired Result - Physical and performance properties of cured epoxy system may lower in proportion to the amount of added. Once Flexer® has been added your piece will remain flexible.
Lower Viscosity - will help with de-airing castable resins and will help laminating epoxies wet out through composite reinforcements (fiberglass cloth, Kevlar, etc.) better.
