Zusammenfassung:A release coating composition includes a curable polysiloxane and an aerosol suppressant that has more than one SiO4/2 unit. The aerosol suppressant includes the polymerization product of a siloxane and a cyclic polysiloxane polymerized in the presence of a polymerization catalyst. The siloxane has units of the chemical formula (SiO4/2)(RaRb2SiO1/2)x wherein Ra is a vinyl moiety, Rb is an alkyl moiety, and x is a number from 1.05 to 4. The release coating composition is formed by combining the aerosol suppressant and a curable polysiloxane. The release coating composition is also used to coat a substrate in a release coating process producing a mist of less than 50 mg/cubic meter measured at approximately 457 m/min.
