Abstract: An improved industrial method for the direct synthesis of alkylhalogenosilanes is described. Specifically, a method is described for preparing alkylhalogenosilanes by reacting, in a fluidized bed reactor, and alkyl halogenide, preferably CH3Cl, with a solid body, which is referred to as a contact body and which includes powdered silicon and a catalytic system including at least one copper catalyst and ?1 and ?2 promoter activities.
Abstract: 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 ?Si—H units and unsaturated, preferably ?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—“Rub-off”—properties.
