Abstract
A one-part curing composition comprising a compound (a) having two or more structural groups, per molecule, expressed by the general formula: ##STR1## wherein R.sup.1, R.sup.2, and R.sup.3 are groups selected from an alkyl group having 1 to 6 carbon atoms, a phenyl group, and a chloromethyl group, and a polymer (b) having two or more isocyanate groups per molecule, has a good stability in storage under conditions which exclude moisture and humidity, and which further cures in the presence of humidity. This composition does not foam under high temperatures and humidities and has a good heat resistance.
