Reactive poly(fluoroalkyl-functional siloxane) oligomers, process for forming the same, and compositions using the same
Reactive poly(fluoroalkyl-functional siloxane) oligomers, method of making the same, and compositions comprising the same are shown and described herein. The reactive poly(fluoroalkyl-functional siloxane) oligomers are is derived from a hydrolysable fluoroalkyl-functional silanes. Coating compositions comprising reactive poly(fluoroalkyl-functional siloxane) oligomer(s) may be used to form a coating or a film on a substrate and impart hydrophobic and/or oleophobic properties. The reactive poly(fluoroalkyl-functional siloxane) oligomer are more hydrophobic and oleophobic and show better chemical resistance than the hydrolysable fluoroalkyl-functional silane.

Polyorganosiloxane having poly(meth)acrylate groups and methods for the preparation and use thereof
A polydiorganosiloxane having both a silicon bonded aliphatically unsaturated group and a silicon bonded poly(meth)acrylate polymer or copolymer, and method for preparation of this polydiorganosiloxane are disclosed. The method preserves the aliphatically unsaturated groups when grafting the poly(meth)acrylate to the polydiorganosiloxane. This polydiorganosiloxane is useful in hydrosilylation reaction curable compositions, such as pressure sensitive adhesive compositions.

Steel Protective Coating Compositions, Methods of Their Manufacture, and Methods of Their Use
Steel sheet coating compositions in which polymeric resin or ceramic properties are produced by admixing an aluminum coordinate complex and an anhydrous, encapsulated, aluminum particle paste, a polysilazane as a source of silicon, an organic solvent, an organic synthesis catalyst, and optionally a non-metallic, non-ionic, low-nucleophilic base. The admixed coating is applied to sheet steel prior to hot-stamping in order to inhibit surface formation of iron oxides and to improve steel sheet surface characteristics.
