Methyl end-stopped dimethylpolysiloxane, low molecular weight polybutene and hydrogenated alkane oil were used as plasticizer in RTV-1 alcohol-silicone sealant and the properties of there sealants was studied.

The acetoxy silicone sealant is prepared with hydrogenated alkane oil, neutral alkane oil and low molecular polybutylene as plasticizer.
