Abstract: A method for the adhesion of a layer of fluorosilicone rubber which is curable using a non-hydrosilylation curing process to a layer of silicone rubber which contains no perfluoroalkyl groups and which is curable using a non-hydrosilylation curing process, comprising the steps of: (i) incorporating either a hydrosilylation catalyst or a siloxane containing at least two silicon bonded hydrogen groups into the fluorosilicone rubber composition prior to curing and; (ii) incorporating the other of the hydrosilylation catalyst or the siloxane containing at least two silicon bonded hydrogen groups into the alternative silicone rubber composition prior to curing; (iii) preparing a mixture compound comprising the products of step (i) and step(ii) and having a weight ratio of the product of step (i) to the product of step (ii) in the range of 40:60 to 60:40; (iv) forming the products of step (i), (ii), and step (iii) into required shapes; (v) bringing the shaped products of step (iv) into contact with the product o

Abstract: A silicone emulsion comprises: (A) a silicone compound comprising an anchorage additive for enhancing the adhesion to a polymer film substrate; (B) at least one surfactant; and (C) water. The anchorage additive is the reaction product of (A1) a fluid polyorganosiloxane containing at least one alkenyl group and at least one silanol group with (A2) a hydrolysable silane containing at least one epoxide group. A water-based anchorage additive comprises the silicone emulsion. A silicone release coating composition comprises: (X1) the silicone emulsion; and (X2) at least one curable silicone composition, e.g. a water-based silicone release coating composition. The curable silicone release coating composition may be applied to a sheet-form substrate and cured to form a release-coated layer having good release property and improved rub-off resistance on the substrate.

Abstract: Filled silicone composition, in situ preparation and use thereof are provided. The composition comprises a mixture of (A) an in situ-prepared treated silica, (B) an in situ-prepared (siloxane-alkylene)-endblocked polydiorganosiloxane, (c) a cure catalyst and (D) a crosslinker. Moreover, the composition can be used as adhesive, coating and sealant.
