US Classification:

427386, 523412, 523403

Abstract:

The present invention relates to a stable aqueous dispersion of thermoplastic polymer particles imbibed with a thermosettable compound. The polymer particles are characterized by having a sufficient concentration of anti-agglomerating functional groups to stabilize the latex against agglomeration. The dispersion is useful as one part of a two-pack formulation.

B32B 2104

US Classification:

427393

Abstract:

The invention relates to wood coating composition selected to accentuate the color and the natural grain structure of the underlying surface of a wood article, such as, a furniture or carving. The surface of the article is coated with a waterborne system that includes a copolymer copolymerized from at least one first copolymerizable monomer and at least one second copolymerizable monomer containing a conjugate base of a strong acid. The coating enhances the reddish-yellow hues and suppress the bluish hues and grays. Such a coating is aesthetically pleasing and it enhances the natural beauty of high quality wood, such as, rose, cherry, teak, mahogany. The present method can be utilized by furniture manufacturers who plan to replace solvent borne coating compositions, such as nitrocellulose-based lacquers, with waterborne coating compositions.

International Classification:

C08K 506

US Classification:

524366

Abstract:

An aqueous aerosol coating composition comprising a blend of neutralized acrylic dispersible polymer having a relatively high Tg, high acid number and low molecular weight, with a drying oil-modified, low molecular weight copolymer in a water-based carrier and propellant system which comprises dimethyl ether, water and a water-soluble organic solvent. Compositions containing the blend of this invention produce polymer coatings that possess improved drying time without adversely effecting other physical properties.
