摘要:
The present invention pertains to low emission polyurethane polymer products based on autocatalytic polyols made by modification of conventional polyols with tertiary amines and processes for their manufacture. The tertiary amine is bound to a conventional polyol by means of an epoxide, epichlorohydrin, or grafting by means of an azo and/or peroxide initiator or sulfonyl azide.
摘要:
A flame retardant epoxy resin composition containing not more than 10% by wgt. of halogen, comprising an epoxy resin, stated concentrations of phosphoric acid ester, nitrogen—containing cross-linking agent having an amine functionality of at least 2 and a catalyst capable of promoting the reaction of the phosphoric acid ester with the epoxy resin and promoting the curing of the epoxy resin with the cross-linker, and optionally a Lewis acid in a stated amount.
摘要:
In summary, the invention is related to the discovery of a class of compounds which inhibits the reaction of a polyepoxide with a curing agent at low temperatures. More particularly the invention relates to an epoxy resin composition comprisinga) a polyepoxide; andb) a cure inhibitor comprising boric acid.
