Abstract
A composition comprising a curable epoxy resin, a reactive diluent, a curing agent for the epoxy resin, and an isocyanate compound is stable at room temperature for extended periods of time and cures to form a part which has good high-temperature properties.
Claims7
A composition comprising:
- (a) a curable epoxy resin;
- (b) an effective amount of a phenolic novolac curing agent having a functionality greater than about 1.75;
- (c) from about 15 to about 150 weight percent, based on the weight of the epoxy resin, of an isocyanate compound which can be represented by the formula
- R--N.dbd.C.dbd.O]n
- in which R is a multivalent substituted or unsubstituted C.sub.1-20 hydrocarbyl moiety and n is an integer equal to the valence of R;
- (d) from about 5 to about 75 weight percent, based on the weight of the epoxy resin, of a reactive diluent selected from the group consisting of unsaturated aromatic monomers, esters or amides of ethylenically unsaturated carboxylic acids, unsaturated cyano-containing compounds, vinyl esters, N-vinyl amides and allyl-containing compounds;
- and
- (e) an effective amount of a free radical polymerization initiator for the reactive diluent.
