  • Patent number: 4985277
    Abstract: A method of making a tack-free silicone gel molding comprises the steps of molding a cross-linked organopolysiloxane into a gel having a tacky surface and a partial three-dimensional network structure which exhibits limited fluidity and deformation upon the application of stress; and coating the tacky gel with cured silicone rubber particles having an average diamter less than about 1 mm. The coating sep may optionally use an aqueous dispersion of the silicone rubber particles, which is then followed by a drying step to obtain a tack-free gel which is also shape-retaining.
