Rotogravure or flexographic printing ink composition containing an

The present invention relates to a curable composition comprising:

Curable aminoplast compositions and catalysts for curing same

Asphalt additive compositions are described which comprise (A) a metallic organic strength improving compound and (B) an anti-strip compound. The metal of said metallic organic compound is selected from the group consisting of manganese, cobalt, copper, vanadium, molybdenum, cerium, iron, nickel, lead, zirconium, barium, calcium and zinc. The preferred metal is manganese. The anti-strip compound is designed to reduce water-induced damage to asphalt paving mixtures.

Asphalt additive compositions

A composition comprising: (A) a non-Newtonian colloidal disperse system comprising (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; and (B) an isocyanate-terminated prepolymer.

One-component moisture curable urethane coating system

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.

Two-component urethane coating system

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.
