Abstract: Solid organopolysiloxane elastomers particularly useful in gasketing applications are prepared from two normally solid addition-curable elastomer components which are not blended together prior to cure, but are contacted with each other, preferably in the form of sheets or films.

Abstract: This invention is directed to a method of preserving polymer emulsions against biodeteriogenic microbe attack and spoilage by combining with the polymer emulsions selected cationic compounds and an ethylenediamine acid compound. The polymer emulsions contain surfactants and/or anionic constituents. It is also directed to polymer emulsion compositions, that are resistant to spoilage by biodeteriogenic microbes, containing surfactants and/or anionic constituents, an ethylenediamine acid compound, and cationic compounds.

Abstract: An inorganic matrix building material with enhanced water impermeability is prepared by curing an inorganic curable matrix and at least one particulate hydrophobic silicone resin substantially uniformly incorporated within the matrix, the at least one hydrophobic silicone resin being selected from the group consisting of a TD resin, an MQ resin, an MT resin, an MQT resin, and combinations thereof. In certain particular instances, the at least one hydrophobic silicone resin is a TD resin. The curing takes place at elevated temperature, optionally at elevated pressure.

Abstract: This invention is directed to methods of incorporating a trigger such as boric acid, boric acid salts, sodium sulfate, or other salts, into a nonwoven web substrate for the preparation of dry nonwoven products which are redispersible when put in contact with large amounts of water or liquid. In one method, the trigger is in a dry powder form and is incorporated into the nonwoven fibers followed by treatment of the fibers with an aqueous redispersible binder, and binding and drying the web. Another method is to saturate a dry bonded nonwoven web with an aqueous solution of the trigger and then dry the saturated web. Yet another method is to apply an aqueous solution of the trigger to the web followed by applying a redispersible aqueous binder to the web and then heating and drying the web.

Abstract: In at least one embodiment, the present invention relates to a silicone non-stick coating, products having these coatings, and methods for making the same. In at least one embodiment, the coating comprises the cured product of silicone resin, silicone fluid, and durability agent.

Abstract: The present invention pertains to a siliconized polyester resin that has a sufficiently high Tg that the siliconized polyester is a solid at room temperature. The silicone polyester preferably has a Tg of 30° C. or greater. The silicone polyester can be produced as a particulate and remain stable at room temperature. The particulate silicone polyester is suitable for use in coating compositions, including powder coating compositions. The coating can be clear or pigmented, and thus optionally can include pigment. The coating composition also includes a crosslinker. The coating composition can be ground into a powder. The powder is stable at room temperature. The powder is then capable of being coated on a suitable substrate and then baked to form a coated metal object.

Abstract: In at least one embodiment the present invention relates to a water repellant coating composition comprising an organic polymer, polysiloxane, an emulsifier, and water. In at least one embodiment, the organic polymer comprises polybutene, an alkyd polymer, an acrylic polymer, or a mixture thereof.

Abstract: In at least one embodiment, the present invention relates to a gypsum composition suitable for use in the manufacture of construction materials comprising a) gypsum, b) water, and c) a water repellancy composition comprising a hydroxy-based cellulose and a siliconate.

Abstract: Nitrogen-containing organopolysiloxanes which may also contain crosslinkable reactive groups are easily prepared by reaction of an alkoxy-functional oligosilane containing methylene linkages between silyl groups and nitrogen with organopolysiloxanes condensable therewith. The nitrogen may be quaternized if desired. The chain amino nitrogens can subsequently be quaternized if desired. Uses for the products include single component crosslinkable compositions.

Abstract: Stoves having a ceramic cooktop mounted within a metal frame with a silicone sealant therebetween are manufactured in a labor saving process involving minimal waste, hand tooling, and cleanup, by providing a leakage-preventing dam paralleling the periphery of the cooktop support surface, positioning the cooktop within the frame, resting on the dam, and applying as a seal, a flowable, curable silicone which cures at a rate such as to allow it to self level, the dam preventing leakage of low viscosity silicone into the stove interior.

Abstract: A low temperature curable silicone rubber composition includes a polysiloxane mixture, a platinum group metal containing catalyst, an inhibitor, a crosslinker, and an alumina powder mixture in an amount of at least 85% of the weight of the curable silicone rubber composition. The alumina powder mixture of the invention includes two or more micronized alumina powders, and in particular, three micronized alumina powders. Advantageously, the silicone rubber compositions of the invention are curable at room temperature with both excellent calenderability and thermal conductivity thereby making these compositions excellent candidate materials for forming gap pads.

Abstract: Organopolysiloxane gel products having a variety of physical forms and which produce a silky feel when applied to the skin are prepared by reacting an unsaturated organopolysiloxane resin, an Si—H functional organosiloxane crosslinker bearing pendant hydrido functionality, a C4 or higher unsaturated hydrocarbon, and optionally, an unsaturated hydrophile component. Products ranging from viscous liquids, creamy gels, pastes, and soft powders may be obtained. The products are highly useful in formulating cosmetic and pharmaceutical products.

Abstract: The use of C2-20 alkyl phenyl silsesquioxane resins in cosmetic formulations provides cosmetics with good feel and water resistance. Lipsticks having excellent transfer resistance and high gloss may be prepared. Sunscreens and body lotions formulated with the resins exhibit improved UV absorbance.
