SILICONE COMPOSITE THAT CAN BE RETICULATED FOR PRODUCING ANTI-ADHESIVE COATINGS FOR FLEXIBLE SUPPORTS AND ADDITIVE TO PROMOTE ADHESION CONTAINED IN THIS COMPOSITE

摘要

The area addressed by the invention is that of silicone composites that are subject to reticulation or have been reticulated, particularly for creating a coating or water-repellent and anti-adhesive film for flexible substrates such as paper or similar in the form of natural or synthetic polymer films. These compounds are of the type that contain reticulating polyorganosiloxanes that have SiH units and unsaturated polyorganosiloxanes, preferably vinylated, suitable for reacting with the reticulating agent in an addition reaction and in the presence of platinum to form the reticulated anti-adhesive coating on the flexible substrate, plus at least one additive (D) to promote adhesion to it. The objective is to propose new liquid silicone compounds that can be applied without using a solvent, which is beneficial, that can be reticulated instantly to produce an anti-adhesive and/or water-repellent coating for the flexible substrate, giving very high quality reticulated silicone coatings, particularly in terms of sticking/adhering to the substrate, being harder to rub off and the anti-adhesion profile (sufficiently increase detaching force at high speed); these latter properties are in particular the result of an additive to help it stick. In order to achieve this aim, the invention proposes silicone compounds in which the attachment-enhancing additive is: M [D]d°_{[Dalcoxy ]d^{a [Dépox}}
