ABSTRACT:
Novel radiation-curable, liquid vinyl organosilicon polymers and coating compositions which are free of volatile solvent(s) and which are adapted to be applied to a substrate and cured rapidly by exposure to radiation to form release coatings having good release properties with respect to adhesives, and methods for producing such polymers and compositions and for applying and curing such release coatings.
The vinyl polysiloxane may be prepared from dimethyl dichlorosilane, vinyl methyl dichlorosilane, and tetrachlorosilane or trichloromethylsilane.
It may be mixed with a polymethyl hydrogen polysiloxane and a photosensitizer and cured by ultraviolet or electron beam radiation.
