PHENOLIC RESIN COMPOSITIONS CONTAINING ETHERIFIED HARDENERS

摘要

This invention relates to a resin composition capable of being thermally cured while minimizing or eliminating voids in the resulting composite, the composition having both a long pot life at low temperatures and a fast curing rate at higher temperatures containing a mixture of (a) a phenol-formaldehyde resole resin, and (b) an etherified hardener, the etherified hardener being prepared from an alkoxylated polyol or a mono epoxy functional diluent.
