Abstract:

A jobsite-renewable floor finish comprising a film former and an appropriate amount of a lightness-inducing agent comprising a core-shell polymer system or sheathed polymer system provides a translucent hardened finish layer having an increased lightness value (as evaluated in relation to an appropriate color space) and a cleaner appearance than a finish made without such pigment.

Abstract:

A method of improving the scrub resistance of a paint is provided. The method involves adding to a paint containing at least one polymeric binder having a glass transition temperature greater than about 20. degree. C. and an average particle size diameter of from about 70 nanometers to about 150 nanometers when said binder is formed from at least one acrylic monomer or from about 100 nanometers to about 50 nanometers when said binder is formed from at least 50% by weight of vinyl acetate, at least one coalescent at a concentration of at least about 10% by weight based on the weight of the polymeric binder and where said coalescent is a solvent for the polymeric binder. The method is particularly useful for improving the scrub resistance of flat latex paints.
