Abstract
A silicone release coating composition is disclosed. The silicone release coating composition comprises: (A) an organopolysiloxane having at least two alkenyl groups in a molecule; (B) an organopolysiloxane having at least two silicon-bonded hydrogen atoms in a molecule; (C) organic modified functional silica particles having an average particle size of 5 μm to 15 μm and a BET specific surface area of 600 m2/g to 800 m2/g; and (D) a hydrosilylation reaction catalyst. The silicone release coating composition can form a coating with a lower release force to sticky adhesive.
