Abstract: The present invention provides acidic compositions and methods that are adapted to impart color to cementitious or mineral substrate surfaces. Specifically, the present invention relates to acidic compositions and methods adapted to treat cementitious or mineral substrate surfaces that have the advantage of using a less corrosive acid-based solution. The acidic composition incorporates species including a weak base in equilibrium with a conjugate acid. The presence of such species moderates the corrosive behavior of the acid while still allowing excellent coloring action to occur.

Abstract: A vinyl polymer pigment dispersing agent having a vinyl addition polymer backbone, one or more polymer side chains with pendant cyclic urea functional group(s) separated from the polymer backbone by at least 10 intervening atoms, and in some embodiments one or more polymer side chains comprising pendant urea functional groups separated from the polymer back-bone by less than 10 intervening atoms. The dispersing agent may be made by addition polymerizing a mixture of one or more vinyl monomers and one or more monomers having cyclic urea functional groups and vinyl functional groups. The dispersing agent may be combined with pigment particles, a carrier and an optional surfactant to make a pigment grind dispersion with excellent pigment wetting and dispersing properties.

Abstract: A coating composition comprising an acetoacyl-functional polymer, an organic solvent, and a crosslinking agent.

Abstract: A coated article including a cement fiberboard substrate and a coating system applied to the substrate, wherein the coating system comprises (i) at least one acid-functional alkali-soluble polymer having a backbone substantially free of linear or branched aliphatic alkyl repeating units having more than 3 backbone carbon carbons, (ii) at least one water-soluble silicate salt and (iii) water.

Abstract: The bottom of a cement fiberboard article is coated by conveying the article across a gap between a first conveyor and second conveyer and applying a liquid radiation-curable coating system to at least the bottom surface of the article while the article passes over the gap. The coating system is radiation-cured to at least a reduced tack state before the coated surface contacts the second conveyor.

Abstract: A substrate may be coated with a various combinations of a water-dispersible polyisocyanate, a water-soluble acid or salt thereof, and/or an isocyanate-reactive compound. The resulting coated article has improved coating adhesion, especially near coated burnished surfaces such as sawn edges or grooves.

Abstract: An aqueous crosslinkable coating composition that includes a PU polymer and a vinyl polymer bearing carbonyl groups (i.e., a carbonyl-functional vinyl polymer) and/or latex polymer. The composition also preferably includes carbonyl-reactive amine and/or hydrazine functional groups.

Abstract: A polyurethane dispersion is prepared by reacting a hydroxy-functional sulfonated unsaturated alkyd with an isocyanate in the presence of one or more vinyl monomers to form a blend containing the vinyl monomers and a sulfonated polyurethane polymer containing ethylenic groups. The blend is dispersed in water and the vinyl monomers are reacted by free radical polymerization.

Abstract: Coating compositions for cementitious substrates may be made from a multistage latex polymer; silane; and a water-soluble acid, acid anhydride or acid salt capable of etching or otherwise reacting with the surface of the substrate to provide improved coating adhesion. The silane my may be present as a silane coupling agent distinct from the multistage latex polymer, or may be present as silane functionality on the multistage latex polymer. The coating compositions adhere well to cementitious substrates and have a self-etching capability which improves coating adhesion, especially near edges and corners.

Abstract: The present invention provides coating compositions that include substantially non-irritating ethylenically unsaturated compounds and have one or more of the following properties: high performance, low VOC levels, substantially no formaldehyde content, and low irritation levels.

Abstract: This invention relates to coating compositions that include water; a latex polymer and a silane coupling agent. The latex polymer preferably comprises acetoacetoxy functionality, or is a multistage latex, or is an acetoacetoxy functional multistage latex. The silane coupling agent is preferably a functionalized silane coupling agent (more preferably an epoxy-functional silane coupling agent). The compositions may be used to coat a variety of substrates, including wood, cement and fiber cement. Articles having the coating applied thereto are also provided.
