SOLVENT-TYPE SILICONE STRIPPER COMPOSITION FOR HIGH CONCENTRATION COATING, WHICH COMPRISES SILICONE POLYMER, POLYMETHYL HYDROGEN SILOXANE, PLATINUM ORGANOMETALLIC COMPLEX, RETARDER AND PETROLEUM SOLVENT

摘要

PURPOSE: A solvent-type silicone stripper composition for high concentration coating is provided, to reduce the deterioration of residual adhesion and the use amount of a solvent and to improve curing property. CONSTITUTION: The solvent-type silicone stripper composition comprises 30-80 wt% of a silicone polymer which has a viscosity of 10-100 g/cm·s at a temperature of 25 deg.C and a relative humidity of 50% and contains an alkyl group of C1-C3 and an alkenyl group of C1-C3 at both ends of a linear chain with a molecular weight of 1,000-100,000 ; 1-15 wt% of a polymethyl hydrogen siloxane which has a viscosity of 0.1-0.4 g/cm·s at a temperature of 25 deg.C and a relative humidity of 50% and contains an alkyl group of C1-C3 at both ends of a linear chain having a molecular weight of 400-4,000; 0.1-1 wt% of a platinum organometallic complex; 0.1-0.5 wt% of a retarder; and 6-29 wt% of a petroleum solvent.
