URETHANE MODIFIED SILICONE POLYMER CAPABLE OF PROVIDING PAINT WITH A HIGH VISCOSITY AND AN EXCELLENT COHESIVE PROPERTY TO A CLEAR PAINT FILM AND SEALANT, AND A MANUFACTURING METHOD THEREOF

摘要

PURPOSE: A urethane modified silicone polymer is provided to be able to improve the adhesiveness to a clear paint film and a sealant when the polymer is applied as an additive to the paint in which acryl polyol and/or polyol applied with acryl silane, non-aqueous dispersable resin, and a melamine curing agent are applied.;CONSTITUTION: A manufacturing method of urethane modified silicone polymer comprises (a) a step of reacting a diisocyanate compound represented by Chemical formula 1: OCN-R-NOC and a blocking agent; (b) a step of performing a urethane reaction by adding polyhydric alcohol to the blocked diisocyanate compound of step a; (c) a step of forming siloxane by adding alkyltrialkoxysilane and catalyst to the compound having passed through step b; and (d) a step of performing hydrolysis by adding alkyltrialkoxysilane and ionized water to the siloxane.;COPYRIGHT KIPO 2013
