<p>PURPOSE:To provide titled compsn. which has improved storage stability, makes one-package formulation possible, and is an addition reaction type and useful for an adhesive, etc., by a method wherein a crosslinker, organohydrogenpolysiloxane is coated with a non-permeable film to encapsulize the crosslinker and the encapsulated crosslinker is blended with other ingreadients. CONSTITUTION:(A) An organopolysiloxane having a unit of the formula [wherein R is (substd.) monovalent hydrocarbon gp.; a is 0.5-3] and at least two alkenyl gp. (bonded to a silicon atom) per molecule and (B) an organohydrogenpolysiloxane having at least two hydrogen atoms (bonded to a silicon atom) per molecule and encapsulated with a non-permeable film (e.g. ethyl cellulose) are mixed with (C) a catalyst for an addition reaction (e.g. a platinum catalyst) to obtain the desired compsn. When the compsn. is used, the wall of the capsule is broken by pressurizing, heating, etc. to cure the compsn. USE:Coating material, molding material, fiber-treating agent.</p> |
