Curable compsn. comprises (A) polyester with alkenyl gps. in the terminal, (B) polyether with polyorganosiloxane residues having at least one Si-H gp. in the terminal and at least two Si-H gps. per mol. with the Si-H gp. content in the polyester being 0.5-10 mol times the total alkenyl gps. in the compsn., (C) 1-30 wt.% of a silicone oil with viscosity at 25 deg.C of up to 10000 centistokes on the basis of the total compsn. and (D) 0.1 ppm-5 wt.% catalyst selected from Pt, chloroplatinic acid and Pt complexes on the basis of the total amt. of (A)+(B). Compsns. contg. polyvinyl with a wt. average mol.wt. 10000-2000000 instead of silicone oil are also claimed. |
