Summary: | The invention concerns a method for preparing a cold-vulcanisable coating composition (CVE), and the resulting composition. The composition comprises a polyorganosiloxane with alkenyl groups bound to the silicium, a polyorganosiloxane with hydrogen atoms bound to the silicium, a catalyst, a ternary adhesion promoter consisting of an alkoxylated organosilane, an organosilicon compound comprising at least an epoxy radical, a chelate of metal and/or a metal alkoxide, a polyorganosiloxane called extender and having terminal siloxyl units with hydrogeno functions, and a reinforcing silicon filler treated in situ by a compatibility agent in the presence of polyorganosiloxane with alkenyl function, said in situ treatment consisting in preparing a filler suspension by bringing said silicon filler in the presence of the compatibility agent and polyorganosiloxane (1), thereby providing the in situ treatment of the filler. The invention further provides an elastomer with high extensibility. |
