摘要:
The present invention relates to polymers polymerized sequentially or in stages and having varied functionality and/or monomer content as the polymerization progresses, as well as the methods for making these polymers. The polymers according to the invention can advantageously be present in aqueous emulsion or latex form and can advantageously be used in paint compositions.
摘要:
Water-borne cross-linking polymeric compositions and related embodiments, such as methods of making and using the compositions, as well as products formed with said compositions are described. For example, the water-borne composition may comprise polymers incorporating cross-linking functionality such as, but not limited to, carbonyl or epoxy functionality, and a blocked cross-linking agent, for example, a hydrazone. The cross-linking functionality does not react with the blocked cross-linking agent; however, the blocked cross-linking agent is capable of reacting with the alternative form cross-linking agent such as, but not limited to, a hydrazide, to yield a cross-linked polymer. The alternative form cross-linking agent may be formed in an equilibrium reaction including the blocked cross-linking agent.

The present invention is directed to a coating composition comprising a vinyl acrylic copolymer latex wherein said copolymer latex has a water contact angle of about 60° or higher on the dried latex film surface, wherein said copolymer latex further has a specific water vapor permeability of about 0.5 mg/cm2/mm/24 hr. The invention is also directed to the copolymer latex itself. Further, the invention is a method of improving a coating's ability to withstand a high humidity environment comprising adding a vinyl acrylic copolymer latex to the coating composition wherein said copolymer latex has a water contact angle of about 60° or higher on the dried latex film surface, and wherein said copolymer latex further has a specific water vapor permeability of about 0.5 mg/cm2/mm/24 hr.

摘要:
The present invention relates to substrates and coating compositions disposed thereon containing improved ultraviolet degradation resistance. Specifically, these coating compositions can contain multiple UV protectants and can advantageously be used in transparent, semi-transparent, and/or translucent coatings on substrates, particularly opaque or semi-opaque substrates such as wood, e.g., in order to inhibit, to reduce, and/or to minimize UV degradation of said substrates.
摘要:
The invention relates to colorant compositions, and aqueous latex paints or other water-borne coatings made from them, which have a mitigated environmental impact. Levels of solvents, additives and impurities comprising volatile non-aqueous constituents, alkylphenol ethoxylates (and derivatives thereof), crystalline silica, and/or formaldehyde are decreased relative to those typical of preceding generations of colorants and tinted aqueous latex paints and other water-borne coatings. On the other hand, paint-performance as indicated by any of Stormer viscosity stabilization, rheological profile flow/leveling and sag resistance, water sensitivity and color transfer resistance is comparable to a paint in which the aforementioned solvents, additives and impurities are still present.
