Abstract:
A vinyl polymer pigment dispersing agent having a vinyl addition polymer backbone, one or more polymer side chains with pendant cyclic urea functional group(s) separated from the polymer backbone by at least 10 intervening atoms, and in some embodiments one or more polymer side chains comprising pendant urea functional groups separated from the polymer backbone by less than 10 intervening atoms. The dispersing agent may be made by addition polymerizing a mixture of one or more vinyl monomers and one or more monomers having cyclic urea functional groups and vinyl functional groups. The dispersing agent may be combined with pigment particles, a carrier and an optional surfactant to make a pigment grind dispersion with excellent pigment wetting and dispersing properties.
Abstract:
A universal colorant system for both solvent- and water-based paints and coatings is contained in a closed sealed pouch or cartridge-style container, and includes a colorant component, a surfactant package including at least one alkyd-compatible surfactant and at least one latex-compatible surfactant, and a carrier. When the colorant system is added to a base paint it desirably provides a mixture having a drop in viscosity of less than about 50%.

Abstract:
Fluid concentrates, colorants and coating compositions contain solid pigment particles dispersed in a nonvolatilizing, reactive liquid diluent having a viscosity less than 1,000 cps and containing at least one molecular species having at least three reactive unsaturated sites. The reactive liquid diluent may serve as one or more of a dispersing medium for the solid pigment particles, a carrier, a coalescent and a humectant, and may crosslink or otherwise cure to form an interpenetrating polymer network in, or crosslink with, a pigmented coating composition containing a film-forming polymeric binder. Embodiments of the reactive liquid diluent can provide colorants and coating compositions having reduced levels of VOCs, conventional carriers, conventional dispersants, conventional coalescents and conventional humectants.

Abstract:
Los concentrados, los colorantes y las composiciones de recubrimiento líquidos contienen partículas de pigmento sólido dispersas en un diluyente líquido reactivo no volátil, que tiene una viscosidad menor que 1000 cps y que contiene al menos una especie molecular que tiene al menos tres sitios insaturados reactivos. El diluyente líquido reactivo puede servir como uno o más de un medio de dispersión para las partículas de pigmento sólido, un portador, un agente de coalescencia y un humectante, y puede reticularse o de otra manera curarse para formar una red polimérica interpenetrante en, o reticulada con, una composición de recubrimiento pigmentada que contiene un aglutinante polimérico formador de película. Las modalidades del diluyente líquido reactivo pueden proporcionar colorantes y composiciones de recubrimiento que tienen niveles reducidos de VOC, portadores convencionales, dispersantes convencionales, agentes de coalescencia convencionales y humectantes convencionales.
Abstract:
Una composicion colorante para ambas pinturas y revestimientos basados en solvente y basados en agua. La composicion colorante universal es una composicion la cual incluye un componente colorante, tal como pigmento, tinta, colorante, agente de entintado y/o agente de efecto metalico; un paquete surfactante que incluye por lo menos un surfactante compatible con alquido; y por lo menos un surfactante compatible con latex; y cuando el paquete surfactante es agregado a una pintura base proporciona una mezcla que tiene una caida en viscosidad de menos de aproximadamente (50%).
