    Abstract: The release composition includes a siloxane polymer having a weight average molecular weight of at least 1000 grams per mole, a first crosslinker and a second crosslinker, each crosslinker independently a compound represented by formula Si(OR5)4 or R1Si(OR5)3, or a compound having at least two groups represented by formula -Si(R4)x(OR5)3-x, and a photoacid generator. The siloxane polymer includes repeating divalent units represented by formula and at least two functional groups selected from silanol, alkoxysilane, -Si(OR2)y(R")3-y, and a combination thereof. In these formulas, each R is independently alkyl, each R2 is independently hydrogen or alkyl, each R" is independently alkyl or aryl, y is 1, 2, or 3, each R4 is independently alkyl or aryl, each R1 and R5 is independently alkyl; and x is 0 or 1. An article including a cured reaction product of the release composition and a method of making the article are also described.

    Abstract: Hydrophobic and oleophobic coatings, methods of making same, and uses of same. A coating can comprise one or more oleophobic and/or hydrophobic layer(s) disposed on a substrate, e.g., a fabric or the like. A layer comprises polymeric particles, which may be at least partially coalesced and/or crosslinked, comprising (co)polymer chains comprising silicon-containing pendant groups. A method of making a layer comprises: coating a substrate with an aqueous dispersion of the polymeric particles; and, optionally, curing the layer, e.g., to coalesce and/or crosslink the polymeric particles. A method of making the aqueous dispersion may comprise: forming a reaction mixture comprising one or more monomers comprising silicon-containing pendant groups; optionally, one or more comonomers; surfactant, and water. Coatings of the present disclosure have use in aerospace applications, automotive applications, building and construction, food processing, and electronics, or the like.

    Abstract: A surface modifying coating for an article that includes a first component having a surface in frictional engagement with a surface of a second component. At least a portion of a surface of one of the components is coated with a coating including a mixture of at least two silicones: (i) a hydrolyzable organopolysiloxane with a viscosity of less than or equal to 1,000 centistokes and that is capable of crosslinking reaction upon exposure to moisture at ambient temperature; and (ii) a second organopolysiloxane copolymerizable with the first hydrolyzable organopolysiloxane and having viscosity of greater than or equal to 5,000 centistoke; wherein the coating provides a maximum break loose force equal to or less than three times a kinetic extrusion force such that stiction is reduced between engaged surfaces. The coating is compatible with high-temperature sterilization methods sometimes used on articles for medical uses, is resistant to leaching, migration and breakdown during long-term aging conditions, and does not require a catalyst, crosslink agent, or additional energy source for preparation or application.

    Abstract: There is provided silicone based materials with enhanced tackiness upon cure. These may be used for cured self-adhering silicone-based products such as pressure sensitive adhesives, self-adhering materials and/or self-sealing materials, made from condensation curable silicone-based compositions, the compositions therefor and to applications for which said self-adhesive products may be used. In one particular application the cured silicone based material may be utilised as a self-sealing layer in an inflatable article such as a pneumatic tire.
