The present invention relates to a method comprising the steps of a) applying a 0.1-mm to 2-mm thick layer of a pigmented coating composition onto a cement, concrete, or asphalt substrate, and b) allowing the coating to composition to dry. The method of the present invention is useful for preparing a traffic paint with improved color retention and durability.

Method for applying a coating composition to a substrate

The present invention relates to a composition comprising an aqueous dispersion of submicron-sized polymer particles and micron-sized polymer beads, wherein the polymer particles or beads or both are functionalized with phosphorus acid groups. The composition of the present invention is useful for providing a matte finish on substrates, such as leather, textiles, wallboard, decorative coatings, concrete, and wood, with improved stain resistance. The present invention also relates to a leather substrate coated with a clear matte finish comprising an acrylic or styrene-acrylic polymer film and micron-sized polymer beads, wherein the film or the beads or both are functionalized with a phosphorus acid monomer.

Phosphorus acid functionalized coating composition

The present invention provides stable, quick drying aqueous compositions useful in making traffic markings having excellent low temperature flexibility which comprise (i) one or more vinyl or acrylic emulsion polymers chosen from single stage and multi-stage emulsion polymers, the polymer or at least one stage thereof having both a calculated glass transition temperature (calculated Tg) of from &#x2212;25 to 0&#xb0; C., and a calculated Hansch parameter of 1.4 to 2.25, and (iii) one or more fillers, extenders and/or pigments, wherein the composition has a percent pigment volume concentration (% PVC) of from 50 to 80% and, preferably, a volume solids of from 50 to 75%. The compositions may comprise one or more silanes, and one or more polyamines and a volatile base, such as ammonia.

Durable aqueous compositions for use in making traffic markings having good dirt pickup resistance and traffic markings made therewith

The present invention relates to a coating composition comprising an aqueous dispersion of a) carboxylate salt functionalized first thermoplastic polymer particles; b) second thermoplastic polymer particles imbibed with a thermosettable compound and functionalized with anti-agglomerating groups; c) an extender; and d) a volatile base. The composition of the present invention is suitable as a waterborne quick-set formulation useful as a traffic paint.

Traffic paint formulation

The present invention relates to a composition comprising an aqueous dispersion of polymer particles and crosslinked polymer beads that are each functionalized with keto groups, and a diamine or dihydrazide crosslinking agent. The dispersions of the present invention are useful in coatings applications.
