A method of inhibiting the loss of solar reflectivity over time of an exterior elastomeric coating composition comprising an organic binder and at least one inorganic additive comprises: replacing at least a part of the at least one inorganic additive with a solid, particulate, organic polymer having a Tg greater than 70&deg; C. An improved exterior elastomeric coating composition is also disclosed.

Coating bituminous substrates

A method for using a thermoplastic elastomeric composition which contains a multi-staged emulsion polymer binder is provided. An elastomeric composition which contains a multi-staged emulsion polymer binder and a photosensitive composition and a method for using the elastomeric composition in elastomeric coatings, caulks, or sealants is also provided.

Multi-staged binder for use in elastomeric coatings, caulks and sealants

This invention relates to modified aqueous dispersions of water-insoluble latex polymer prepared by swelling an initial water-insoluble latex polymer, prepared by emulsion polymerization, with additional ethylenically unsaturated monomer, including at least one monomer with two or more sites of ethylenic unsaturation, and subsequently polymerizing the additional monomer within the swollen latex particles.

Modified latex polymer compositions

A method for improving the quality of a mastic coating system by using a latex barrier tiecoat which is composed of a water-insoluble latex polymer and a multivalent metal ion. The tiecoat is applied to a substrate and then a mastic coating is applied to the tiecoat to yield a mastic coating system having excellent resistance to blistering when the mastic coating system is exposed to long-term ponded water.

Latex barrier tiecoat for use with mastic coatings

Modified solution polymer compositions useful for films, coatings, caulks, adhesives, and mastics having advantitious properties such as low surface tack, short drying time, high tensile strength, and hardness, uses of such compositions, and processes for preparing them are disclosed.

Modified solution polymers for coatings, films, mastics, caulks, and

There are disclosed radiation curable compositions containing (a) about 5-95% by weight of at least one .beta.-cyanoethoxyalkyl acrylate, (b) about 1-90% by weight of a photopolymerizable acrylated polymer or oil, and (c) from 0 to about 5% by weight of a photoinitiator. The compositions are useful in providing 100% solids coatings and adhesive compositions which are capable upon exposure to radiation, and which are useful in a variety of applications such as for coating textiles and fabrics, for producing pressure sensitive adhesives, and for producing laminating adhesives.

Radiation curable compositions containing .beta.-cyanoethoxyalkyl

Monoethylenically unsaturated derivatives of substituted benzophenones or acetophenones which are prepared by reaction of such a benzophenone or acetophenone with a vinyl benzyl halide, such as the chloride, are polymerizable to form homopolymers or copolymers e.g. with a wide variety of conventional ethylenically unsaturated monomers, especially monoethylenically unsaturated vinyl or vinylidene monomers. The resulting polymers are sensitive to radiation, such as ultraviolet light, e.g. having a wave length of 2,000 to 5,000 angstroms, and readily cross-link or cure upon exposure to such radiation. Adhesives, binders, coatings, and impregnating compositions are made from the polymers.

Radiation-curable monomers and polymers thereof
