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.

Isocyanurate polyisocyanate and its use as a curing agent for a

A process for preparing a modified aliphatic, alicyclic or araliphatic organic polyisocyanate composition which comprises heating an aliphatic, alicyclic or araliphatic organic polyisocyanate composition having at least two isocyanate groups in one molecule at a temperature of from about 100.degree. C. to about 200.degree. C. in the presence of an aliphatic, alicyclic or araliphatic organic diisocyanate monomer in an amount of at least about 1/2 of the weight of the organic polyisocyanate composition and removing unreacted aliphatic, alicyclic or araliphatic organic diisocyanate monomer.
