<p>Crosslinkable compositions containing (A) organopolysiloxanes with alkenyl groups, (B) linear organo-hydrogen-polysiloxanes and (C) hydrosilylation catalysts, in which (B) is obtained by the co-hydrolysis of diorganodichlorosilanes, monochlorosilanes and optionally dichlorosilanes with water (where at least the mono- or di-chlorosilanes contain silicon-hydrogen groups). Crosslinkable compositions (V) containing (A) organopolysiloxanes with alkenyl groups, of formula (1), (B) linear organopolysiloxanes with diorganosiloxy units and Si-H groups, obtained by the co-hydrolysis of diorganodichlorosilanes, monochlorosilanes and optionally dichlorosilanes with water (where at least the mono- or di-chlorosilanes contain Si-H groups), and (C) hydrosilylation catalysts (for aliphatic C=C double bonds). R : SiC-linked, optionally substituted 1-18C hydrocarbyl with no aliphatic C=C double bonds; R' : SiC-linked, optionally substituted 1-18C hydrocarbyl with at least one aliphatic C=C double bond; R" : R or R'; m : 40-1000; n : 0-10; (m+n) : 40-1000. Independent claims are included for (1) formed products obtained by crosslinking (V) (2) a method for the production of coatings by applying (V) to a substrate surface and then crosslinking the composition .
