    摘要: This invention relates to solventless release coating organopolysiloxane composition and sheet-form substrate having cured release coating, providing a solventless release coating organopolysiloxane composition having a viscosity of 50 to 3,000 mPa s, comprising (A) 100 parts of an organopolysiloxane fluid having a viscosity at 25° C. of 10 to 1,000 mPa s and alkenyl content of 0.10 to 3.0 wt %; (B) 0.5 to 15 parts of a diorganopolysiloxane having a viscosity at 25° C. of 10,000 to 150,000 mPa s, and 0.05 to 0.30% of alkenyl groups at the pendant position of its siloxane-chain and trialkylsiloxy-terminals; (C) a prescribed quantity of an organohydrogenpolysiloxane; and (D) a hydrosilylation reaction catalyst. Also, a cured release coating-bearing sheet-form substrate that has a cured coating from this solventless release coating organopolysiloxane composition is provided.
