Abstract: An aqueous dispersion of a silicone pressure sensitive adhesive base can be combined with a curing agent and cured to form a silicone pressure sensitive adhesive. The aqueous dispersion of the silicone pressure sensitive adhesive base includes a bis-hydroxyl-terminated polydiorganosiloxane; a polyorganosilicate resin; cumene; a surfactant; and water. A curing agent such as a peroxide compound or an aminosilane may be combined with the aqueous disperison of the silicone pressure sensitive adhesive base to form a silicone pressure sensitive adhesive composition. A pressure sensitive adhesive article may be formed by a method including coating a surface of a substrate with the silicone pressure sensitive adhesive composition, removing water, and curing the silicon pressure sensitive adhesive composition to form a silicone pressure sensitive adhesive on the surface of the substrate.

Abstract: A process for preparing a waterborne dispersion of a silicone pressure sensitive adhesive base includes the use of a solventless polyorganosiloxane pellet containing a polyorganosilicate resin and a polyorganosiloxane gum. The waterborne dispersion of the silicone pressure sensitive adhesive base can be combined with a free radical initiator, and dried and cured to form a silicone pressure sensitive adhesive.
