PHENOL HARDENER FOR EPOXY RESIN AND EPOXY RESIN COMPOSITION USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a hardener for an epoxy resin excellent in adhesion with inorganic materials or metals, and an epoxy resin composition. SOLUTION: The hardener contains a phenol hardener and a silane coupling agent having a tertiary or quaternary amino group. The amino group may be desirably an imidazole group, a dimethyl amino group or their salts. The hardener may be a mixture of above two or be a modification obtained by stiring and mixing the silane coupling agent having the tertiary or quaternary amino group with the phenol hardener melt, and is effective in improvement of adhesive property with inorganic materials and metals.
