Hydroxyl terminated polyfunctional epoxy curing agents |
| abstract |
A tri- or tetraglycidyl derivative of an aromatic diamine, aminophenol, or polyphenol and a diglycidyl ether of a bisphenol are reacted with a bisphenol, in the presence of a catalyst at elevated temperature, to yield a reaction product wherein each glycidyl group is effectively endcapped with a moiety containing a free hydroxyl group. The ratio of equivalents of polyglycidyl compound to diglycidyl compound is 1 to 4 to 1 to 1, and of bisphenol to total giycidyl compounds is 1.8 to 1 to 2.4 to 1. Said product is useful for curing solid epoxy resins. The epoxy resins cured by said product have a dense crosslinked network resulting in concomitant superior coating properties especially chemical resistance while maintaining good flexibility. |
