WACKER® SG 3381 is a polyalkylene oxide-modified polydimethylsiloxane that contains organo-functional groups in the α,ω-position. This unique structure gives a functional value of 2 per modified polydimethylsiloxane. The functional groups are chemically bonded to the polydimethylsiloxane through chemically inert alkylene spacer groups, which are highly stable to hydrolysis.
