<p>A silicone emulsion which can be converted into an elastomeric product under ambient conditions by eliminating and evaporating water and alcohol or carboxylic acid, comprising by weight approximately (A) 100 parts of a hydroxyl-terminated polydiorganosiloxane having a molecular weight of at least about 50,000, (B) 1 to 400 parts of a low molecular weight, reactive acyloxy or alkoxy-functional silicone resin, (C) 0.1 to 20 parts of a catalytic compound, (D) 0 to 200 parts of a thixotropic filler and (E) 0 to 200 parts by weight of a non-thixotropic filler, the silicone emulsion having a solids content of about 20 to 85% by weight. The emulsion is especially suited for coatings and sealants.</p> |
