Method for vulcanizing a green tire using an organopolysiloxane-based mold release agent lubricant composition

Crosslinkable or crosslinked silicone compositions that can be used, in particular, to form a non-stick and water-repellent coating or film for flexible substrates and in the form of natural or synthetic polymer films are provided. These compositions comprise crosslinking organopolysiloxanes bearing SiH units and unsaturated organopolysiloxanes, preferably vinyl organopolysiloxanes, capable of reacting with the crosslinker by addition reaction, in the presence of platinum in order to form the non-stick crosslinked coating on the flexible substrate, and at least one crosslinking and attachment-promoting additive X. These compositions are advantageously free of solvent and can be crosslinked instantaneously into a non-stick and/or water-repellent coating for a flexible substrate.

Organopolysiloxane composition suitable for vulcanisation into an elastomer at room temperature and new organopolysiloxane polycondensation catalysts

Crosslinkable or crosslinked silicone compositions, forming water-repellent and release coating for a flexible heat sensitive support of paper or polymer, and comprising crosslinking polyorganosiloxanes (POSs) bearing &#x2261;Si&#x2014;H units and unsaturated, preferably &#x2261;Si-Vi, vinyl-containing POSs, capable of reacting with the crosslinker by polyaddition, in the presence of platinum in order to form the crosslinked release coating on the flexible support. The object is enabling the coating composition to crosslink instantaneously to produce, on various flexible supports (paper, e.g. glassine, or polymer, e.g. polyester such as polyethylene terephthalate PET), a crosslinked silicone coating leaving the coating machine, with excellent attachment (adhesion) and mechanical strength or cohesion&#x2014;'Rub-off'&#x2014;properties. The invention uses, per 100 parts by weight of silicone base, of 1 to 40 parts by weight of an additive comprising from 1 or 5 to 80% by weight of particulate filler, preferably nanoscale filler, in a silicone oil reacting with the crosslinker.

The invention relates to cross-linkable or cross-linked silicone compositions that can be used, in particular, to form a non-stick water-repellent coating for flexible substrates, for example paper or similar, in the form of natural or synthetic polymer films.

Silicone composites subject to reticulation or 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 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. A new liquid silicone compound 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.

The invention concerns an aqueous dispersion of viscous silicone oils capable of being crosslinked into an elastomer by water elimination (condensation). The invention aims at obtaining an aqueous silicone dispersion corresponding to an optimal compromise in terms of adherence of the crosslinked elastomer on all types of supports, and the colloidal stability of the dispersion during preparation and storage. Said aqueous dispersion comprises a viscous silicone oil A, optionally a crosslinking agent B, optionally an adhesion promoter C (silane), a filler D, a catalyst E, an emulsifier F, optionally a functional additive G and water.
