NOVEL POLYUREAS BASED ON IPDI, HDI, THEIR ISOCYANURATES AND AMINES

摘要

Disclosed is a novel polyurea based on (A) an isocyanate compound that is isophorone diisocyanate (IPDI), hexamethylene diisocyanate (HDI) or their isocyanurate and (B) a diamine or polyamine, such as isophorone diamine (IPD). The polyurea remain stable in a solid form at a curing temperature of 150-220ÀC standard for powder coating without releasing a significant quantity of organic materials or water and is useful in the paint industry.
