摘要:
The invention concerns a lubricating organo-functional silicone oil, whether or not in emulsion. The invention aims at improving oils and lubricating silicone emulsions, in terms of emulsion stability, transfer and flow of the oil in emulsion on metal surfaces, of stripping lubricating power, non-clogging of molds and paintability of molded metal articles when used for stripping. In order to achieve said aim, the inventive POS oil is functionalized with the lubricating organophilic radical W (C12-C20 alkyl) and with a radical bearing one or several adhering functions such as diacid, thiol, phosphonate, sulphonate hydroxy, hydroxyamine, amine, ether, amide and their combinations. The invention also concerns emulsions whether or not containing additives, based on said WY functionalized POS oils, the preparation of said oils and said emulsions and their uses when stripping metal articles molded in metal moulds.

摘要:
A functionalized silicone with perfluorinated polyorganosiloxanes (POS) Rf is used to produce coatings with low surface energy and improved adherence to supports. The compositions include a group POS A bearing, per molecule, bis-perfluoromalonate grafts Gf, functional radicals Fa of the amine (HALS) fa1, epoxy fa2, (poly)ether fa3, carboxy fa4 type, and optionally alkyl groups Galk. The invention is useful for producing soil release coatings for textiles.
摘要:
The invention concerns a method for preparing high purity polyorganosiloxanes with arylalkyl function(s) by: hydrosilylation of a hydrogenopolyorganosiloxane, reagent (SiH), and an aromatic monovinyl compound, reagent (Vi), with simultaneous introduction of reagent (SiH) and reagent (Vi), in a reaction medium containing an inert solvent and a hydrosilylation catalyst; then elimination of the solvent, the possible residual reagents (SiH) and (Vi), and/or hydrogenation, the hydrogenation process being optionally followed by an elimination process (or another elimination process) of the products other than polyorganosiloxanes with arylalkyl function(s). The resulting silicones with arylalkyl function(s) can be used as emollients and/or carriers in cosmetic compositions, or as solubilizing agents and emollients in perfume compositions.
