Abstract
This invention relates to an aqueous silicone emulsion which forms a silicone elastomer upon the removal of water having improved adhesions to substrates. The silicone emulsion comprises the product form by mixing a diorganosiloxane polymer, water, surfactant, optionally a crosslinker, a tin condensation catalyst, optionally an acid and an effective amount of an aminofunctional siloxane which is formed by reacting an aminofunctional silane and a hydroxy-endblocked organosiloxane.
