A water-based coating composition is described herein. The composition includes an aqueous dispersion derived from an ethylenically unsaturated monomer and one or more organic solvents. The composition when applied to a substrate and allowed to dry provides a wet look to the substrate.

A roofing membrane is provided that includes at least one substrate at least partially impregnated with a first asphalt coating composition and a liquid parting agent emulsion applied to the upper surface of the asphalt-coated substrate. The liquid parting agent emulsion comprises one or more thermoplastic polymers and about 15 wt. % to about 40 wt. % of at least one mineral filler, based on the weight of the total solids in the emulsion. The first asphalt coating composition is free of oxidized asphalt.

An exterior sheathing cementitious panel which prevents water penetration and air leakage is provided methods for manufacturing exterior sheathing cementitious panels with a highly efficient integrated air/water barrier membrane are provided as well.

The present invention relates to primer compositions in powder form that comprise a dispersion powder based on an acrylate polymer having a glass transition temperature in the range from 50 C. to +30 C. and cement. The compositions of the invention are notable for good water barrier effect, good dust-binding capacity, and a low tendency toward salt efflorescence. The compositions find use in the priming of masonry, concrete, rendered surfaces, abraded render, plaster surfaces, wall blocks, wood, and ceramic tiles. They can also be used as adhesion promoters with nonabsorbent substrates such as glazed ceramic or glass tiles, metal surfaces, or surfaces of plastic.

A method is provided to fabricate a green desiccant wheel. A green recycled adsorbent material of aluminum hydroxide and alumina is extracted and used as a base material to be added to a 3-dimensional (3D) network skeleton of a foam support. Through sintering, surface is hardened with the material adsorbed to megapores uniformly distributed. Thus, an adsorbent material of porous ceramic having pores on surface is made. The area contacting with moist air is increased. The moisture-adsorbing capacity is improved. At last, the whole procedure is integrated to develop a high-efficiency green desiccant wheel. Thus, the reusable materials are kept at innate grade or upgraded for recycling and regenerating. New materials and products can be further fabricated. The present invention helps solving environmental problem of wastes. Life cycle of resource is lengthened. A sample of recycling economy is innovated. Industrial efficiency is effectively enhanced.
