Abstract: An aqueous organic pigment dispersion used to integrally color concrete and other building materials which includes: alkali metal silica particles as a binder; organic pigment; water; and dispersing agent in an amount effective to disperse the organic pigment and the binder in the water. A method for preparing the aqueous organic pigment dispersion includes (i) mixing, at 3,000 to 10,000 rpm, alkali metal silica particles; organic pigment; and dispersing agent, thereby forming a dispersion premix; (ii) milling the dispersion precursor in a mixer filled with glass beads for a period of time sufficient to reduce the particle size of the organic pigment to about 100 to about 300 nanometers, thereby forming a non-standardized dispersion; and (iii) standardizing the dispersion against a color standard by adding water.

Abstract: A water repellent solution for wood includes an organo-metallic complex of a hydrophobic fatty acid coordinated with a halogenated trivalent chromium and water having a reduced pH prior to mixing with the complex. The solution imparts water repellency and a preservative effect to the wood. Wood treated with the solution has the treatment bonded thereto by a reaction between the wood and the solution.

Abstract: An elastomeric adhesive composition useful in resurfacing applications is provided. The composition includes a liquid dispersion of a polar latex resin binder, a chemical plasticizer, a volatile glycol ether solvent and a thickening agent. The binder is an emulsion of water and a polyvinyl acetate homopolymer with a polyvinyl alcohol protective colloid and is present in a concentration effective in adhering a resurfacing fabric to a surface wetted with the composition. The chemical plasticizer acts to plasticize and tackify the latex resin binder. The thickening agent is present in an amount effective to modify the viscosity of the composition so that it will not flow once applied to a surface. In addition, the invention comprehends a resurfacing composition and a method of resurfacing.

Abstract: A paint comprising a solution of an internal phase comprising pigment and latex resin and an external phase comprising an amine soluble resin dissolved in water is disclosed. The amine soluble resin has a molecular weight sufficiently high that it imparts desirable film properties while maintaining surface applicability of the paint. Upon evaporation of the water, the external phase forms a substantially continuous film encapsulating the internal phase. The invention also comprehends a novel method of paint formulation.

Abstract: A drier catalyst for use in coating compositions which contain polyunsaturated oils comprises a coordination complex of tri n-octylphosphine oxide and the manganese salt of a hydrocarbon-soluble carboxylic acid, such as octoic acid. The catalyst is unaffected by the presence of zinc compounds or iron in the coating composition.

Abstract: Use of ethyl hydroxy ethyl cellulose to aid in dispersion and suspension of pigment and control of application rheology in inorganic zinc-rich primers made with partially hydrolyzed ethyl silicate resins is described.
