Glass Fiber Wire Varnish

They are suitable for various types of double-glass fiber-covered wires, polyimide wires, polyester film-covered wires, F-46 composite film-covered wires etc.The products are primarily composed of epoxy, polyester, and silicone-based oil varnishes, with water-based polyester varnished as a secondary option. They have high solid content, good wetting-ability of glass fibers, strong adhesion, environmental friendly, and high temperature resistance.
