HY-512 water-based epoxy resin fiber sizing agent product image

HY-512 Water-Based Epoxy Resin Fiber Sizing Agent

This product is a modified high-performance water-based epoxy resin emulsion with a self-emulsifying system design. It forms a uniform and dense protective film on the fiber surface, greatly enhancing the interfacial adhesion between fibers and resin matrices and significantly improving interfacial shear strength. It can be widely used for the sizing treatment of various chemical fibers such as carbon fiber, basalt fiber and glass fiber.
