    Abstract: A film may be formed from film forming compositions which comprise at least one carboxamide based coalescing solvent. These coalescing solvents impart equivalent or improved wet-scrub resistance, block resistance, gloss, dirt pick-up resistance and leveling characteristics to the films on a substrate, without contributing to total VOC levels, when replacing conventional coalescing solvents. The present invention also includes a method for forming a film comprising applying a film forming composition comprising polyunsaturated reactive carboxamides to a substrate and curing the film under ambient conditions. The coalescing carboxamide solvents are suitable for paint, latex based caulk, adhesives and floor care applications.

    Abstract: Disclosed are the use of novel surfactants for the synthesis of emulsion polymer latexes, particularly those used in paints, coatings, and pressure sensitive adhesives. The surfactant compositions for emulsion polymer latexes comprise sterically bulky surfactants whose composition comprises at least one alkoxylated polyaryl substituted aromatic sulfosuccinate compound. The novel surfactants provide for the production of stable, small particle size distribution emulsion polymer latexes. The resulting latexes, when formulated into latex paint, impart improvements in water resistance as measured by film opacity, blister resistance and improved leveling characteristics, and when formulated into pressure sensitive adhesives, provide improved water resistance characteristics as measured by film opacity.
