ABSTRACT:
Cured elastomers prepared by the reaction of a hydroxyl-terminated polyorganosiloxane with curing agents containing silicon-bonded aminoxy and/or amido groups can be painted when a dialkoxysilane of the formula X'R.sup.1 SiR.sup.2 (OR.sup.3).sub.2 is present in the curable composition. In the foregoing formula R.sup.1 is alkylene, haloalkylene or oxyalkylene, R.sup.2 and R.sup.3 are individually hydrocarbon, alkoxy-hydrocarbon or halohydrocarbon radicals and X' is glycidoxy, mercapto, acryloxy, methacryloxy, NH.sub.2, --N(C.sub.2 H.sub.5).sub.2 or --N(H)CH.sub.2 CH.sub.2 NH.sub.2.
