Abstract
Solventless organopolysiloxane compositions are disclosed which, when coated on a substrate and cured, will release adhesives with moderate force. These compositions are useful for coating flexible substrates such as paper, laminated paper, synthetic film and metal foil which are used as wrapping paper for asphalt, tapes, labels, etc. These compositions consist essentially of a mixture of a low-viscosity, vinyl-containing organopolysiloxane, an organohydrogenpolysiloxane, a vinyl-containing organosiloxane copolymer resin and a hydrosilylation catalyst.
