A water swellable cross-linked elastomer and method of preparation is provided. The elastomer can advantageously be included in skin treatment compositions. Swellable elastomers in accordance with the invention are particularly well suited for inclusion in skin tightening cosmetic products. The elastomers can be formulated to form a film. When applied to skin, an elastomer in accordance with preferred embodiments of the invention can adhere to the skin and shrink as it dries. This can provide a skin tightening, lifting and wrinkle smoothening effect upon drying. This effect can temporarily mask the appearance of wrinkles.

The invention is related to azetidinium-containing copolymers and vinylic monomers and their uses in formation of non-silicone hydrogel coatings on silicone hydrogel contact lenses.

A coating composition contains: (A) 60 to 99% by weight of a urethane-based resin emulsion having film-forming ability in terms of a solid content ratio; and (B) 1 to 40% by weight of a silicone-acrylic graft copolymer resin emulsion having an average particle size of 180 nm or less in terms of a solid content ratio, wherein a weight ratio of a polyorganosiloxane represented by a specific chemical formula to an acrylic acid ester unit or a methacrylic acid ester unit is 30:70 to 99:1.

Marine coatings including cationic polymers hydrolyzable to nonfouling zwitterionic polymers, coated marine surfaces, and methods for making and using the marine coatings.

Durable, anti-fouling, crosslinked zwitterionic coatings that are grafted to the surface of a substrate through covalent bonding are disclosed. When exposed to a light source, zwitterionic monomers react with a crosslinker and with activated radicals at the surface of the substrate, simultaneously forming the crosslinked zwitterionic coating and anchoring it to the surface of the substrate. Photomasking techniques can be used to micropattern the zwitterionic coatings. The zwitterionic coatings can be applied to a variety of substrates, including medical devices and systems.

An ultraviolet light-curable coating composition includes 5-40 weight percent of an ultraviolet light-curable poly(polyphenylene ether) oligomer; 60-95 weight percent of an ultraviolet light-curable monomer, oligomer, polymer, or a combination thereof; and 0.01-3 weight percent of a photoinitiator.

The purpose of the present invention is to provide a weather-resistant hard coat composition for a glass-substitute substrate capable of efficiently forming a coating film excelling in weather resistance, scratch resistance, and toughness. The present invention provides: a weather-resistant hard coat composition for a glass-substitute substrate, the composition containing a polyorganosilsesquioxane having a constituent unit represented by Formula (1); a cured product thereof; and a laminate having a glass-substitute substrate and a coating film formed on at least one surface of the glass-substitute substrate. The coating film is a layer of a cured product of the weather-resistant hard coat composition for a glass-substitute substrate. [In formula (1), R.sup.1 represents a group containing an active energy ray-curable functional group.]

A silicone septum having a surface coating. The coated silicone septum may be incorporated in an intravenous catheter assembly. The coating reduces static charge among a plurality of vibrating silicone septa during manufacture of the intravenous catheter assembly. The surface coating includes a coating agent selected from a bicarbonate salt and a siloxane polyalkyleneoxide copolymer. The bicarbonate salt may be an alkali metal bicarbonate. The siloxane polyalkyleneoxide copolymer may include copolymer groups selected from ethyleneoxide, octamethylcyclotetrasiloxane, and mixtures thereof. The silicon septum may be coated by contacting an exterior surface of the silicone septum with a coating solution of a solvent and the coating agent for at least 5 minutes. The coating agent has a concentration in the solvent greater than 1 wt. %. Excess coating solution is removed from the exterior surface of the silicone septum. The exterior surface is dried to remove the solvent, forming the surface coating.
