CHAIN EXTENDER COMPOSITION FOR TWO-COMPONENT POLYURETHANE PAINT AND PAIN COMPOSITION CONTAINING THE COMPOSITION

摘要

The present invention relates to a chain extender composition for a two-component polyurethane coating and a coating composition containing the composition, and more particularly, an amine compound such as an alkyl amine compound, an imino alkyl amine compound, and an aspartic alkyl amine compound It consists of a contained chain extender composition and a coating composition containing the composition. The chain extender composition composed of the above components provides a polyurethane coating composition that exhibits physical properties comparable to those of the conventional chain extender MOCA while having low human harm.
