US Classification:

427196, 252 62, 118311, 427426

Abstract:

Compositions and methods for their application are described herein. The compositions include a plurality of particles having a density of 1000 kg/mor less (e.g., a pre-expanded polymer) and a binder. Also described herein is a method of applying the composition onto a surface. The method includes blowing a plurality of particles having a density of 1000 kg/mor less in at least one first stream and spraying a binder in at least one second stream onto a surface. Further provided is an apparatus for spraying the composition.

Abstract:

Coating compositions and methods for their preparation are described. The coating compositions can include a first copolymer produced by emulsion polymerization and derived from one or more monomers including one or more (meth)acrylates, one or more acid monomers, and optionally styrene. The first copolymer can have a Tg from −50 C. to −23 C. and is present in an amount of 10-50% by weight based on the total polymer content. The coating compositions can also include a second copolymer produced by emulsion polymerization and derived from one or more monomers including one or more (meth)acrylates, one or more acid monomers, and optionally styrene. The second copolymer can have a Tg from −15 C. to 25 C. and is present in an amount of 50-90% by weight based on the total polymer content. Further described herein are dried coatings, methods for coating a substrate, and methods for producing a coating.
