Title: Self-adhering silicone compositions and preparations thereof

Abstract: Mixing vinyl-containing polydiorganosiloxane, an organosilicon compound containing silicon-bonded hydrogen atoms, a platinum catalyst, and an amidosiloxane provides a composition which exhibits improved adhesion to many substrates without the use of a primer when heat cured in contact with the substrate. An example of the amidosiloxane is ##STR1## The compositions have self-adhering properties and also exhibit an extended pot life. The compositions can be prepared by mixing the polydiorganosiloxane, platinum catalyst, and amidosiloxane into one package of a two package product and the organosilicon compound forms the other package. The two packages are mixed before use to form a curable product.
