Silicone oil-in-water emulsions containing a polysiloxane containing polymer is prepared by first preparing a polysiloxane containing polymer by the polymerisation of siloxane containing monomers and/or oligomers in the presence of an inert organopoly siloxane and/or an organic fluid, a suitable catalyst and optionally an end-blocking agent; and quenching the reaction if required. If required one or more surfactants may be introduced into the polysiloxane containing polymer to form a homogenous oil phase. Water is then added (in an amount of 0.1-10 percent by weight based on total oil phase weight) to the homogenous oil phase to form a water-in-oil emulsion. Shear is applied to the water-in-oil emulsion to cause inversion of the water-in-oil emulsion to an oil-in-water emulsion. Finally, if required the oil-in-water emulsion can be diluted by adding more water.

This relates to the coating of air bags, which are used for safety purposes to protect occupants of vehicles such as automobiles, and of air bag fabrics intended to be made into air bags. In particular the invention relates to the top coating of air bags and air bag fabrics which have been pre-coated with a cured organic resin coating composition. The top-coat is an anti-blocking coating composition comprising at least one solid lubricant dispersed in an organic polymer binder. A process for applying the top-coat is also described.

The present disclosure relates to comb or brush polymers and, in some approaches, comb or brush polymers suitable for use as viscosity index improvers in lubricating oil compositions. The present disclosure further relates to oil compositions comprising such polymers. The disclosure also relates to brush polymer compositions derived from sulfur functionalized polydialkylsiloxane backbones and various (meth)acrylate monomers.

A mechanical method of making an oil-in-water microemulsion containing (A) a polysiloxane and (B) an inert fluid selected from an inert siloxane fluid and an inert organic fluid, where the average emulsion particle size is between 1 and 140 nanometers, is disclosed. The process involves the following steps: i) preparing an oil phase comprising a polysiloxane containing mixture by the polymerization of silane or siloxane containing monomers and/or oligomers in the presence of an inert fluid, a suitable catalyst and optionally an end-blocking agent; and ii) where required quenching the polymerization process; wherein the inert fluid is substantially retained within the resulting polysiloxane containing mixture; iii) if required, mixing one or more surfactants into the oil phase; iv) adding water to the oil phase, followed by applying agitation or shear to the mixture to arrive at an oil-in-water microemulsion; v) optionally diluting the oil-in-water microemulsion by adding more water.

New compositions of matter that provide lubricant properties when cured into a coating on a substrate. The compositions are low molecular weight structured polysilicate compositions that have high silanol contents. The polysilicates are combined with a condensation catalyst and allowed to cure on the appropriate substrate. The cured coating has lubricant properties.

A composition and method for reducing the coefficient of friction and required pulling force of a wire or cable are provided. A composition of aqueous emulsion is provided that is environmentally friendly, halogen free and solvent free. The composition is compatible with various types of insulating materials and may be applied after the wire or cable is cooled and also by spraying or submerging the wire or cable in a bath. The composition contains lubricating agents that provide lower coefficient of friction for wire or cable installation and continuous wire or cable surface lubrication thereafter.
