A curable composition, storable under substantially anhydrous conditions is obtained by mixing under substantially anhydrous conditions, below 60.degree.C. and under shear conditions which do not substantially alter filler structure, 100 parts by weight of a hydroxyl endblocked polydimethylsiloxane, 70 to 150 parts by weight of a finely divided agglomerated precipitated acicular calcium carbonate, 35 to 200 parts by weight of an organic solvent, from 12 to 20 parts by weight of a monalkyltriacetoxysilane and a catalytic amount of an organotin carboxylate. Exposing this curable mixture to atmospheric moisture and allowing the organic solvent to evaporate provides a cured concerent solid elastomeric material which is paintable with at least one type of decorative organic base paint which forms a continuous roating over the surface and adheres thereto. Silicone rubber compositions are also described which when cured to elastomers have paintable surfaces. |
