  • Patent number: 12098276
    Abstract: Formulations and coatings that seal and protect sensitive natural porous stone, such as, calcareous stone from acid etching. The formulations include one-part and two-part formulations for coating calcareous stones in interior and exterior environments. Various formulations of the invention may include an acrylic hybrid polymer dispersion, a polyurethane dispersion binder, and water. The polyurethane dispersion binder may include one or more acrylic urethane hybrid polymer dispersions or acrylic dispersions or acrylic hybrid polymer dispersions. The acrylic hybrid polymer dispersion may be an epoxy-acrylic hybrid polymer dispersion. The two-part formulations may further include a first hydroxyl function acrylic binder dispersion and a second epoxy functional silane hardener that are mixed together to form the coatings of the invention.

  • Publication number: 20240246859
    Abstract: Dispersion-based ready-to-use grout formulations, methods of making such dispersion-based ready-to-use grout formulations, and the resultant grout products that perform as reactive resin grout products. The grout formulations of the invention at least include a water-based acrylic polymer dispersion binder and optionally a water-based acrylate copolymer dispersion binder, in combination with one or more of an alkaline cross-linker, one or more silane adhesion promoters and/or a micro-fiber filler, along with various other constituents, to provide one-part ready-to-use grout formulations that require no mixing prior to use thereof. The resultant grout products of the invention meet performance standards of epoxy grout products, without requiring mixing of composition parts and without any adverse side effects.

  • Patent number: 11492529
    Abstract: Thermally conductive cementitious compositions for use in flooring installations that are applied over a heat radiating flooring system to increase the thermal conductance of the flooring system and increase the rate of heating the flooring system. The thermally conductive cementitious compositions include a cementitious composition, amorphous flake graphite carbon, and an aqueous solution suitable for use as a thermally conductive mortar, grout or adhesive for flooring installations. The thermally conductive cementitious compositions also include a cementitious composition, mesh fine aluminum oxide, mesh coarse aluminum oxide, and an aqueous solution that provides a thermally conductive mortar, grout or adhesive for use in flooring installations.

  • Patent number: 10294153
    Abstract: Methods of formulating, premixed cement-based tiling compositions and application of such premixed cement-based tiling compositions as an adhesive or grout. The premixed cement-based tiling compositions include a premixed cementitious formulation having a pH and an alkali activation constituent. The premixed cementitious formulation includes an aluminous or a calcium aluminate cement slurry in an amount of about 35 wt. % to 50 wt. % in combination with one or more filler or modifier materials present in an amount of about 40 wt. % to 65 wt. %. The alkali activation constituent destabilizes the premixed cementitious formulation by increasing the pH thereof to generate a reaction between the premixed cementitious formulation and the alkali activation constituent resulting in the cement-based tiling composition for use as an adhesive or a grout. The alkali composition may be sodium hydroxide supersaturated with lithium carbonate.

  • Patent number: 10259749
    Abstract: Grouts, grout products and methods of applying such grouts that include a urethane-acrylic hybrid polymer dispersion (UA-HPD) and a filler material. The UA-HPD may be present in an amount of about 10-40% by weight of the composition, while the filler material may be present in an amount of about 60-90% by weight of the composition. Additional filler materials may also be provided within the UA-HPD grout composition to provide the resultant UA-HPD grout with desired characteristics and properties. The UA-HPD containing grouts are applied between spaced-apart tiles and/or masonry to fill voids and/or joints there-between.
