etc. and are referred to as emulsion paints, water-based paints or water-dilutable paints. The polymeric resin binders are generally present in the form of very fine particles and as the paint dries or cures, these particles coalesce forming the paint film. Thus, the compositions of this inv...
Each of the above compounds was added to a commercial vinyl acrylic latex paint (The Sherwin-Williams Company, Classic 99® semi-gloss latex paint) in an amount of 25 g thickener (20% solids) per 1000 g paint. Paint viscosities were measured by a Stormer viscometer (50 to 200 sec-1she...
The binder is preferably a latex prepared by free radical emulsion polymerization. Most preferably, the binder is a core/shell type latex having a softer core and a harder shell. The use of the above-described comonomer and surfactant enables the paint formulator to prepare paints which exhibit...
Preparation of latex compositions is well known in the paint and coatings art. Any of the well-known free-radical emulsion polymerization techniques used to formulate latex polymers can be used in the present invention. Such procedures include, for example, single feed, core-shell, and inverted c...
methylene chloride layers could be completed only after filtration of the solid phase causing the formation of a persistent emulsion. (Solid phase -- product A). The separated organic layer was washed with water, dried with anhydrous magnesium sulfate and then the methylene chloride was evapro...
Sherwin-Williams continued to introduce new products to the consumer during this time. Kem-Tone, the first emulsion-based, fast-drying paint for the do-it-yourself market was introduced in 1941 and met with remarkable success. Kem-Tone helped deal with the raw material shortage that the nation...
