    Abstract: A highly filled system is provided which employs the combination of coated filler particles and a compatibilizer to allow extremely high filler loading while maintaining a low viscosity. The compositions of the present invention allows a filler level which was previously unachievable due to the increase in viscosity which is particularly evident when extremely small (nanometer sized) filler is added to a system containing conventional (micron sized) filler particles. This is accomplished through selection of a coating for the filler and selection of a compatibilizer which improves the affinity between the filler and the polymer, thereby improving nanometer sized filler wetting and dispersion and allowing the filler to be incorporated into the polymer matrix.

  • Patent number: 6831127
    Abstract: In a silicone rubber composition of the condensation curing type comprising a diorganopolysiloxane having at least two silicon-attached hydroxyl or hydrolyzable radicals as a base polymer, and a silane having at least two hydrolyzable radicals or a partial hydrolytic condensate thereof, at least 2 mol % of the entire substituent radicals attached to silicon atoms in the diorganopolysiloxane are monovalent hydrocarbon radicals having at least two carbon atoms. The cured composition has excellent non-staining and sealing properties, and when applied as a coating, filled into joints, or used as a solid gasket, it does not cause staining of the building, joints, or the area around joints.

  • Patent number: 6825248
    Abstract: This invention provides a light white mineral oil-based fluidized polymer suspension (FPS) composition for use as a rheology modifier in paper coatings. It has been found that by using a selected composition of low viscosity oil as a carrier, high solids content and environmental friendly fluidized polymer suspensions of water soluble cellulose derivatives, synthetic water soluble polymers, guar gum and derivatives, starch and derivatives and mixtures thereof, can be prepared. The FPS of the present invention was found to provide unexpected beneficial performance properties when added as a rheology modifier to a paper coating containing standard binders, pigment, and water. The oil-based fluid polymer suspension composition of the present invention for use as a rheology modifier in the paper coating comprises: a hydrophilic polymer, b) an organophilic clay, c) a surfactant stabilizer, and d) a light white mineral oil having selected properties.

  • Patent number: 6770690
    Abstract: A silicone rubber composition for use in rubber construction materials contains dispersed particles having a photocatalytic activity. The particles are surface-treated with a compound that can easily be deteriorated by the photocatalytic activity under outdoor exposure to ultraviolet light. Rubber construction materials made of the cured form of the composition, when exposed to ultraviolet light, undergo surface hydrophilization that endows them with excellent stain resistance, and also have excellent sealing properties. When the composition is applied as a coating, filled into joints, or used as a solid gasket, it does not cause staining of the building, joints, or the area around joints.

  • Patent number: 6720368
    Abstract: The invention provides a matt, thixotropic paint formulation comprising a resin system and a matting agent. The matting agent comprises a hydrophobic metal oxide, which has a surface moiety (i.e., one or more surface moieties) selected from the group consisting of trimethyl silyl, vinyl dimethyl silyl, acryl dimethyl silyl, and dimethyl silyl. Morever, the paint formulation is characterized by having thixotropic properties such that it does not sag at a notch height of about 75 &mgr;m when measured with an anti-sag meter after application to a substrate. The invention also provides a method of producing such a paint formulation. The invention further provides a substrate having a surface coated with the matt, thixotropic paint formulation of the invention.
