Title:
FLAME RETARDANT EPOXY RESIN COMPOSITION
Document Type and Number:
Japanese Patent JPH0525369
Kind Code:
A
Abstract:
PURPOSE:To obtain the subject low-viscosity composition, containing an epoxy resin, an acid anhydride, a curing accelerator and a filler composed of specific hydrated alumina with hardly any generation of toxic gases, having high flame retardancy and excellent in operating efficiency. CONSTITUTION:The objective composition is obtained by blending (A) an epoxy resin such as bisphenol A with (B) an acid anhydride such as methyltetrahydrophthalic anhydride, (C) a curing accelerator such as 2-ethyl-4- methylimidazole and further (D) hydrated alumina having <=30 dioctyl phthalate oil absorption in an amount of 250-500 pts.wt. based on 100 pts.wt. component (A) as a filler.
