Polyepoxide, catalyst/cure inhibitor complex and anhydride
摘要：
An epoxy resin composition comprises a) a polyepoxide, b) a cure inhibitor of boric acid, a Lewis acid derivative of boron, an alkyl borane, a mineral acid having a nucleophilicity value “n” of greater than zero and less than 2.5, or an organic acid having a pKa value of 1 or more, a catalyst which can be complexed with the cure inhibitor, and c) more than 30 parts by weight per 100 parts by weight of polyepoxide of a cross-linker such as a polycarboxylic acid or anhydride including a copolymer of an ethylenically unsaturated anhydride and a vinyl compound, or a hydroxy-functional compound such as a copolymer of styrene and hydroxystyrene.
