<P>PROBLEM TO BE SOLVED: To provide an organopolysiloxane composition for masking which does not cause a gap between a member and a masking material even to the member having a complex surface shape, is excellent in adhesion, has a property to easily peel from various kinds of constitution members when peeled, and further cures at room temperature requiring no complicated process such as heating and UV irradiation, a masking application method using the composition as the masking material, and the member applied by the application method. <P>SOLUTION: The liquid organopolysiloxane composition for masking contains (A) diorganopolysiloxane whose molecular chain both terminals are blockaded by a hydroxysilyl group, alkoxysilyl group or alkoxy alkoxysilyl group and whose viscosity at 25°C is 20-1,000,000 mPa s, (B) a silane compound having 3 or more hydrolyzable groups bonded to silicon atoms in the molecule and/or a partially hydrolyzed condensate of the same, (C) a cure accelerating catalyst, and (D) a transition metal compound whose components are different from the components of (C). <P>COPYRIGHT: (C)2013,JPO&INPIT |
