  • Patent number: 5990234
    Abstract: The invention provides a liquid composition for coating surfaces, comprising: polymer droplets dispersed in a liquid component, ultraviolet light (UV) absorber, and defoamer. The liquid component comprises water, and volatile organic solvent. The organic solvent comprises a first and a second ether. The first and the second ether are miscible with water. The UV absorber and the defoamer are dispersed in the liquid component. A preferred embodiment of the invention provides the liquid composition with a particulate composition to provide a material for superior non-skid surface coatings, such as non-skid flooring surface coatings. Thus, the invention provides a material for making non-skid coatings, comprising: a particulate composition including wollastonite particles, cellulose particles, and diatomaceous earth particles.
