摘要：
A novel isocyanurate polyisocyanate is disclosed containing N,N',N"-tris(6-isocyanatohexyl)-isocyanurate in an extremely high proportion and having an extremely low viscosity. The novel isocyanurate polyisocyanate is excellent not only in compatibility with a polyol having a low polarity but also in solubility in a solvent having a low polarity as well as in a polar solvent. The novel isocyanurate polyisocyanate is very useful as a curing agent for a two-component polyurethane composition, especially a two-component polyurethane coating composition. The two-component polyurethane coating composition of the present invention is capable of providing a coat film having extremely excellent properties.
