Epotec® Resin and Curing Agent System for Resin Transfer Molding (RTM), Resin Infusion (RI), and Hand Lay Up is designed to have low initial viscosity and reactivity from few minutes to several hours at ambient temperature. The choice is made depending on process conditions and geometry of the component and end use requirements. Epotec® Systems can be used for lamination in combination with different reinforcements and honeycombs to make high strength light weight structural components for sporting goods, marine, aeronautics, automobiles, electrical insulation, wind energy, tools, and fixtures.
