Abstract: A crosslinked polymer dispersion comprising a preformed polymer, selected from the group consisting of silicon modified organic polymers, mixtures of silicon modified organic polymers, mixtures of silicon modified organic polymer(s) with regular organic polymers, mixtures of silicon modified organic polymer(s) with siloxane polymers, mixtures of above polymers, and mixtures of above polymer(s) with organic plasticizers or solvents.

Abstract: This invention relates to an aqueous silicone emulsion which forms a silicone elastomer upon the removal of water having improved adhesions to substrates. The silicone emulsion comprises the product form by mixing a diorganosiloxane polymer, water, surfactant, optionally a crosslinker, a tin condensation catalyst, optionally an acid and an effective amount of an aminofunctional siloxane which is formed by reacting an aminofunctional silane and a hydroxy-endblocked organosiloxane.

Abstract: An aqueous silicone emulsion which upon the evaporation of the water forms a surface modified elastomeric silicone material providing improved coverage and adhesion of paint and reduced staining and coefficients of friction, each relative to other silicone elastomers from aqueous emulsions. The silicone emulsion comprises (A) water; (B) a plurality of particles dispersed in the water comprising a crosslinked product of a diorganosiloxane polymer; (C) a surfactant; and (D) an amount of an oxygen curing compound or a salt thereof effective for the surface modification. If a surface active salt of an oxygen curing compound is used, it may not be required to add additional surfactant in order to form the silicone emulsion.

Abstract: This invention relates to a method of sealing openings in structural components of a building to reduce the amount of smoke which may pass through the opening in the event of a fire. The method comprises filling an opening in a structural component of a building with a support material; applying a coating of a silicone composition over the filled opening and allowing the silicone composition to cure into a continuous elastomeric film having certain properties. These silicone compositions exhibit pseudo plastic rheology which facilitates their application by spraying.

Abstract: The longevity of a surface driving oil layer on a room temperature vulcanizable silicone sealant is increased by adding zinc oxide to a non-acidic composition and exposing the composition to atmospheric moisture which forms the surface drying oil layer on an air exposed surface.

Abstract: A curing agent mixture for curing alkaline phenol/formaldehyde resins containsA) a pulverulent or fibrous filler andB) a carbonic ester.

Abstract: A dividing apparatus for dividing, cutting, or severing a continuously running strip material with the apparatus including an articulated drive for effecting a stroke movement of a cutting unit. The articulated drive is constructed as a quadrangular linkage including a driven crank and a rocker lever pivotally connected to the driven crank through a coupling member. The rocker lever includes an extension portion extending beyond a pivotal connection of the coupling member with the rocker lever. A secondary drive lever is provided with a first end of a link member being pivotally connected with the secondary drive lever and a second end of the link member being pivotally connected with a free end of the extension portion of the rocker lever. A transmission link element is provided for moving the cutting unit with the transmission link element being adjustably connected with the secondary drive lever.
