Storage-stable, curable polyorganosiloxane compositions, whether solvent-free, in solution in an organic solvent or in aqueous emulsion, contain (A) a polydiorganosiloxane having silanol endgroups, (B) a polydiorganohydrosilane, and (C) a catalytically effective amount of a latent tin catalyst of the formula (1): ##STR1## and are cured into elastomeric state by heating to a temperature at least equal to the decomposition temperature of the latent catalyst (C); such polyorganosioxane compositions are well adopted for the thin-layer coating of a wide variety of useful substrates, e.g., paper.
