Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
185 words
A glass-run for a window glass moving to open and close of a motor car, which comprises a substrate material having a film coated on at least a part of the surface of the substrate to be contacted with the window glass, said film being formed by hardening a paint composition comprising: (A) 100 parts by weight of an urethane prepolymer obtained by the reaction of a polyester polyol having hydroxy groups in its terminal and a molecular weight of 1,000 to 3,000, synthesized from a saturated diol having 2 to 6 carbon atoms and an organic dicarboxylic acid having 4 to 6 carbon atoms, with an organic diisocyanate in the molar ratio of NCO/OH of from 0.6/1 to 0.95/1; (B) 10 to 60 parts by weight of a castor oil polyol; (C) 1 to 100 parts by weight of an urethane prepolymer having isocyanate groups in its terminal obtained by the reaction of a low molecular polyol and an organic diisocyanate; (D) 2 to 100 parts by weight of a fluoro resin; and (E) 5 to 100 parts by weight of a silicone oil.
