HY-512 Waterborne Epoxy Resin Fiber Sizing Agent
HY-512 Waterborne Epoxy Resin Fiber Sizing Agent
HY-512 is a modified high-performance waterborne epoxy resin emulsion with a self-emulsifying system. It forms a uniform dense protective film on the fiber surface and improves interfacial bonding between fibers and the resin matrix.
Product Features
Greatly improves interfacial bonding between fibers and resin matrix and increases interfacial shear strength.
Treated fibers disperse well in composite systems and can enhance tensile, flexural and surface wear properties.
Environmentally friendly solvent-free formula; dilutable with water and easy to use.
Excellent compatibility with mainstream thermoplastic resins such as PA and PC for thermoplastic composite molding processes.
Improves fiber bundling and wear resistance while reducing fuzzing and fiber breakage.
