UNSATURATED POLYESTER RESIN WITH WITH EXCELLENT SOFT-FILL PROPERTY AND POLYURETHANE RESIN FOR PAINTS USING THE SAME

摘要

Disclosed are an unsaturated polyester resin containing fluorine in the chain to enhance soft-fill properties and at the same time to enhance physical properties of a surface, and a polyurethane resin for paints using the same. The polyurethane resin for paints according to the present invention comprises: (A) an unsaturated polyester resin; (B) a curing agent; (C) a quencher; and (D) an organic solvent. The unsaturated polyester resin (A) may include: 25-50 wt% of a polyhydric alcohol; 25-60 wt% of a basic acid; 0.5-10 wt% of hydroxyl-terminated polybutadiene; and 0.5-10 wt% of a fluorinated alcohol.
