Water soluble polymers are incorporated into cellulose adhesives comprising phenol formaldehyde and related formaldehyde resins to impart more resistance to sagging and to increase the open time of the adhesive. A preferred use of the modified adhesive is as an adhesive for assembling engineered wood products such as strand board, particle board, medium density fiberboard, plywood and engineered products such as I-beams. The water soluble polymers achieve the objectives of increased sag resistance and more open time by increasing the viscosity of the adhesive and slowing the loss of water to the cellulose products and the air during use of the adhesive.

The present invention contemplates the provision of two-component urethane coating compositions comprising a first component comprising an organic polyfunctional isocyanate, and a second component comprising an acidic ester of a phosphoric acid, the alcohol portions of said acidic acid being selected from the group consisting of hydrocarbyloxy and hydroxy-substituted hydrocarbyloxy compounds, such compositions providing enhanced corrosion resistance properties as well as improved flame retardency and metal adhesion characteristics over the two-component urethane systems of the prior art. An essential ingredient in the compositions of the invention is a non-Newtonian colloidal disperse system which can be provided with either the first component and/or the second component parts of the compositions of the invention. The non-Newtonian colloidal disperse systems provided in accordance with the present invention comprise (1) solid metal-containing colloidal particles predispersed in (2) a disperse medium of at least one inert organic liquid and (3) as an essential third component at least one member selected from the class consisting of organic compounds which are substantially soluble in said disperse medium, the molecules of said organic compound being characterized by polar substituents and hydrophobic portions. The invention also relates to a method of coating a substrate comprising mixing the foregoing components and depositing the resulting composition on said substrate.

A composition and process for improving the curing of concrete, the composition comprising a Singapore dammar resin dissolved in an organic solvent. In a preferred embodiment of this invention, the resin-solvent solution is dispersed in a water-based emulsion by the use of an appropriate emulsifying agent. A preferred organic solvent is mineral spirits, and preferably the organic solvent contains a low enough level of photochemically reactive liquids to meet air pollution requirements such as Los Angeles Rule 66.

The present invention relates to a curable composition comprising: (A) at least one aminoplast resin; and (B) an amount effective to cure the composition of at least one catalyst which is a sulfo acid, or an anhydride, ester, ammonium salt or metal salt of the acid. The sulfo acid can be exemplified by sulfonic acids, such as 2-acrylamido-2-methylpropane sulfonic acid, or a reaction product of the sulfonic acid and a phosphorus acid or salt, such as a dihydrocarbyl phosphorodithioic acid. The catalyst allows curing of aminoplast resins to be accomplished at low temperatures, while imparting a high degree of water resistance to the cured coating.
