ABSTRACT:
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.
