摘要： It has been found that non-blushing coatings of high gloss, long pot life and fast cure time may be obtained by using an epoxy curing agent which comprises an epichlorohydrin-metaxylylenediamine reaction product selected from the group consisting of N,N'-bis(3-aminomethylbenzyl)-2-hydroxytrimethylenediamine, the higher oligomers of N,N'-bis(3-aminomethylbenzyl)-2-hydroxytrimethylenediamine and mixtures thereof and a melting point depressant such as a benzyl alcohol or water and an alcohol solvent and, optionally, a tertiary amine such as N,N'-bis(3-(dimethylamino)propyl)-urea.

摘要： The blocking of the primary amine groups of Mannich base epoxy curing agents with a proton donor to prevent reaction with atmospheric carbon dioxide and moisture and provide low temperature cure is accomplished by reacting a phenol-aldehyde with a polyamine or polyamine-epoxy adduct and further reacting with a proton donor.
