This invention provides compositions and methods to durably increase or decrease the wetting properties of a surface. In certain embodiments the methods utilize a polyquaternary ammonium compound to decrease wettability of the surface or a cationic polysaccharide to increase wettability of the surface.

Durable modification of the wetting properties of a surface

Methods are provided for protecting exterior surfaces of automobiles and other products, or components of products, against abrasion, abrasive dust, water, acid rain, etc. The methods involve applying to a surface a protective coating composition comprising an emulsion selected from the group consisting of a vinyl-acrylic copolymer emulsion and a vinyl acetate-ethylene emulsion. The emulsion is dried to form a water-resistant protective coating that can be removed from the underlying surface by peeling when no longer desired.

Polymeric peel-off coating compositions and methods of use thereof

A vehicle masking material and method of use. The masking material in one embodiment includes a dextrin, a plasticizer, and water. The masking material may additionally include a surfactant. The masking material is applied to a surface which is to be protected from paint overspray or other coating processes, allowed to dry, and the surface is coated (e.g. with paint). After drying of the paint, or other coating, the masking material is removed by water washing.

Protective coating compositions and methods of use thereof

This invention provides for primer/masking compositions that have differential adhesion properties for glass-like and non-glass surfaces. The compositions are used in a method of applying a finish to a non-glass surface which resides in proximity to a glass-like surface without substantially overcoating the glass-like surface. The method involves applying to the glass-like surface a primer/masking composition comprising a vinyl chloride copolymer emulsion, a coalescer, and a surfactant; applying the finish to the non-glass surface, and removing the primer/masking composition from said glass-like surface.

Primer-paint mask composition and methods of use thereof

A solvation-based method for charging toner particles in a liquid electrophotographic developer composition is provided. The method makes use of a material containing specific salvation sites which are incorporated into the resinous phase of the toner, and a charge director which is a metal salt, the metal, cationic component of which is effective to form a highly stable, 'solvated' charged toner complex. Toner and developer compositions are also provided which make use of the novel solvation-based mode of charge direction.

Solvation-based charge direction of electrophotographic developer

A composition is provided for protecting exterior surfaces of automobiles and other products against abrasive dust, acid rain, etc. The composition is applied as a mixture of water solubilized acrylic acid copolymer, pH-neutral acrylic copolymer, alkyl alcohol, surfactant, and water. The composition dries on the exterior surface to form a tough flexible coating that can be removed by an alkaline aqueous detergent solution.

Protective coating composition and method of using such composition

This invention provides for provides for abrasive compositions and methods of use of these compositions for the preparation of surfaces for the application of various coatings such as paints, lacquers and varnishes. The abrasive compositions of this invention provide rapid cleaning and dulling of the underlying surface rendering it suitable for the application of paints or other finishes.

Method of abarding using surface abrasion compositions

This invention provides methods and compositions for the temporary protection of activated plastic surfaces. The methods involve application of protective coating compositions to activated surfaces thereby protecting the surfaces from oxidation, soiling and mechanical damage. The coatings may be easily washed off leaving a clean activated surface suitable for overcoating.

Compositions and methods for the temporary protection of activated

Toner and liquid developer compositions for use in color electrophotographic processes are described. The developer compositions display high particle-mediated conductivity and charge and thus give rise to a final print of exceptionally high quality. Methods of manufacturing the toner and developer compositions are also disclosed, as are novel charge control agents and processes for using the various compounds and compositions in a consecutive multicolor image development.

A composition is provided for protecting exterior surfaces of automobiles and other products against abrasive dust, acid rain, etc. during delivery for sale. The composition is applied as a mixture of water solubilized acrylic acid copolymer, ph-neutral acrylic copolymer, alkyl alcohol, surfactant, and water. The composition dries on the exterior surface to form a tough flexible coating that can be removed by an alkaline aqueous detergent solution.
