Description:

WEXP-85 is a double-component black curable thermal-conductive & flame-retardant Epoxy Encapsulating, with low adhesive and excellent flow and it can penetrate into the gap of products; it can be solidified through normal temperature or heating with suitable speed of solidification; there is no bubble with plain and glazing surface and high hardness; the solidified materials have an excellent performance of anti-alkaline, waterproof, oil- proof and dust-proof, which is humid and thermal resistant and air aging; it owns excellent electric and physical features of insulation, anti-pressing and high degree of adhesive.

Main Features:

1. Low Viscosity, Smooth Casting

2. Faster curing, filling port surface bright and clean.

3. Flammability Property and Electric Property are good
