Abstract
PURPOSE: To provide a phenolic resin compsn. having improved flexibility and impact resistance without deteriorating heat resistance, by blending a bisphenol type epoxy resin and a novolak type epoxy resin with a solid phenolic resin.
CONSTITUTION: 3W20pts.wt. solid bisphenol type epoxy resin having an epoxy equivalent of 170W4,000 and 0.5W10pts.wt. solid novolak type epoxy resin such as cresol novolak type or halogenated novolak type epoxy resin, are blended with 100pts.wt. solid phenolic resin such as a novolak type and/or resol type phenolic resin. Said phenolic resin may contain 3W20pts.wt. (per 100pts.wt. phenolic resin) hexamethylenetetramine.
