Low VOC universal paint colorant compositions

Abstract

A universal colorant composition for both solvent- and water-based paints and coatings. The universal colorant composition is a composition which includes a colorant component, such as pigment, dye, colorant, tinting agent and / or metal effect agent; a surfactant package including at least one alkyd-compatible surfactant; and at least one latex-compatible surfactant; and when the surfactant package is added to a base paint it provides a mixture having a drop in viscosity of less than about (50%).

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Patent Application Serial No. 60 / 663,040, filed March 18, 2005, which is incorporated herein by reference. Background of the invention [0003] Paints and coatings are often used to protect surfaces from erosion, oxidation, or other types of deterioration, and to provide decorative effects. [0004] Organic solvent-based (alkyd) paints or coatings are homogeneously dispersed mixtures of viscosities ranging from thin liquids to semi-solid pastes, which include film-forming polymeric binders, water (solvent), pigments, and other additives. Together, the binder and the solvent form what is known as the "vehicle". Latex or latex paints or coatings are homogeneously dispersed mixtures of viscosities ranging from thin liquids to semi-solid pastes that include a film-forming polymer binder, water (solvent), paint, and other additives. Together, the binder and the solvent for...

Also, these compositions generally do not contain low levels of volatile organic compounds ("VOC"), and / or they are not universal, for example, they are not suitable for use in both alkyd paints or coatings and latex paints or coatings
