Title:
EPOXY RESIN COMPOSITION AND POWDER COATING MATERIAL
Document Type and Number:
Japanese Patent JPH1192628
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To obtain the subject composition excellent in crack resistance, impregnation property, etc., and capable of being used as a powder coating material for a high speed rotary element by including an epoxy resin, curing agent, curing accelerator, inorganic filler and specific stress moderating agent. SOLUTION: This epoxy resin composition contains (A) an epoxy resin as a mixed resin of preferably (i) a bisphenol type epoxy resin having 450-1000 epoxy equivalent and (ii) a novolak type multi-functional epoxy resin having 190-220 epoxy equivalent, (B) curing agent (preferably an acid anhydride, amide, etc., and especially preferably dicyandiamide), (C) a curing accelerator (preferably an imidazole, and especially preferably an imidazole-based azine derivative), (D) inorganic filler (preferably a fused and crushed silica, a spherical silica, etc.), and (E) a styrene-butadiene rubber as a stress moderating agent. Thereby, a powder coating material for fixing a coil of a high speed rotary element in a starter motor for a bike and a four-wheeled automobile, can be expected.
