DMS V33 by Gelest (Mitsubishi Chemical) is a vinyl terminated polydimethylsiloxane. Can be employed in addition cure systems like platinum catalyzed hydrosilylation reaction and peroxide activated cure systems which involve peroxide induced free radical coupling between vinyl and methyl groups. Curing provides strength, hardness, consistency and optical properties. Applications include ceramic-, dielectric- and optical-coatings. DMS V33 complies with TSCA.
