The tack of a polymeric substrate is reduced by (i) coating a surface of the polymeric substrate with a thermosetting liquid silicone rubber composition, (ii) applying an aqueous suspension of powdered silicone rubber with a mean particle size of 0.1 to 500 micron to the coating of thermosetting liquid silicone rubber composition on the polymeric substrate, and (iii) heating the coated polymeric substrate to cure the thermosetting liquid silicone rubber composition and simultaneously adhere the powdered silicone rubber to the coating on the polymeric substrate.

Coatings for polymeric substrates

The present invention relates to a method for controlling foam in a foam producing system comprising adding to the foam producing system a dispersible silicone composition comprising (I) a silicone composition prepared by reacting (i) a polyorganosiloxane, (ii) a silicon compound, optionally (iii) a finely divided filler, and (iv) a catalytic amount of a compound for promoting the reaction of the other components and (II) a hydrocarbon oil. The hydrocarbon oil is effective as a dispersing agent for the silicone composition (I). The hydrocarbon oil-containing compositions are easier to handle, and produce less waste and its dispersion into mineral oil based formulations is more efficient.
