摘要:
Disclosed are hydrophobic finish compositions and cementitious articles made with the hydrophobic finish compositions. In some embodiments, the article is a waterproof gypsum panel surface reinforced with inorganic mineral fibers that face a flexible and hydrophobic cementitious finish possessing beneficial waterproofing properties. These waterproof gypsum panels have many uses, such as, tile backer board in wet or dry areas of buildings, exterior weather barrier panel for use as exterior sheathing, interior wall and ceiling, and roof cover board having water durability and low surface absorption. The flexible and hydrophobic cementitious finish can include fly ash, film-forming polymer, preferably silane compound (e.g., alkyl alkoxysilane), an extended flow time retention agent including either one or more carboxylic acids, salts of carboxylic acids, or mixtures thereof, and other optional additives. Preferably a pre-coated non-woven glass fiber mat is employed to provide the inorganic mineral fibers for the surface reinforcement.

A surface treatment composition including polymeric complex nanoparticles used in a hydrophobic agent and siloxane complex nanoparticles used in a suspending agent thereof. The composition of the present invention is a solution comprising a plurality of components. The primary components are an acid mixture and a base mixture that are combined together in a manner to be described herein to produce a two-part liquid solution. The two parts, are combined together prior to application to a surface and allowed to cure on the surface.

摘要:
A process for manufacturing the composition coating may include selecting a wood or masonry material substrate and utilizing a sol-gel comprising a silane or silane derivative and metal oxide precursor to coat the substrate. The process may utilize an all solution process or controlled environment for manufacturing a composition coating that prevent wetting and/or staining of a substrate,. The composition coatings for treating wood or masonry materials improves weather-resistance, microbial resistance, stain-resistance and fungal-resistance of the materials. The reduced permeability of the resulting masonry materials can also delay or inhibit degradation caused by permeation of ions such as chlorides and sulfates. In addition, a stain comprising the composite solution and pigments may impart additional property to wood or masonry materials whilst retaining or improving the original appearance, particularly for the visibility and contrast of the wood grain as seen after the application of the coating.

摘要:
A method and a porous article are provided.In said method, a porous article which comprises a matrix material in a solid state and pores therein,is processed at least some of the pores being open to an outer surface of the article. A flowing treatment substance is applied to the outer surface of the article and into at least some of the pores. The flowing treatment substance is allowed to react with the outer surface of the article and surfaces of said at least some of the pores such that a hydrophobic coating layer is established on surfaces thereof. An excess of the flowing treatment substance is removed from the article, and the hydrophobic coating layer established on the outer surface of the article is converted into a hydrophilic coating layer.

The invention relates to a preparation for chemical treatment of glass, ceramic and stone surfaces consisting of esters of fatty acids, monomeric organo-silicon compounds and organic solvents. Glass, ceramic and stone surfaces treated with the invention show excellent hydrophobicity and shine. Furthermore, the application of the invention prevents damages of the treated surfaces caused by abrasion during transport, abiding of fingerprints on the treated surfaces and dust accumulation on the treated surfaces.
