Product Description
Product Details
Introduction
This product is a tetrafunctional glycidyl amine high temperature epoxy resin, the epoxy resin molecular structure has a number of epoxy groups and aromatic rings, in the curing process can form a high crosslinking density and aromatic density, so that the cured product shows good heat resistance, high mechanical strength, low curing shrinkage, radiation resistance, water resistance, good resistance to chemicals and other characteristics.
In addition, due to the low viscosity, easy to operate, solvent-free operation can be achieved for the higher requirements of heat-resistant grade of electrical cast insulation products, carbon fiber and glass fiber winding, pultrusion, lamination, pre-preg process molding composite products.
Product Features
Excellent long-term heat resistance Excellent chemical resistance
Good mechanical strength persistence Excellent radiation stability
Low shrinkage Long storage period
