POLYISOCYANATE COMPOSITION HAVING EXCELLENT FOULING RESISTANCE AND ANTI-TACK PROPERTY

摘要

PROBLEM TO BE SOLVED: To provide a sealing material specifically low modulus and excellent in fouling resistance and an anti-tack property by using a polyisocyanate composition comprising few urethane bond-containing resin and low viscosity without using any low-molecular weight compound causing the deterioration in surface tackiness.;SOLUTION: The polyisocyanate composition is characterized by containing (A) an isocyanate-terminated prepolymer obtained from an aliphatic and/or an alicyclic diisocyanate monomer; (B) a photocurable substance, and is used for the sealing material.;COPYRIGHT: (C)2002,JPO
