ABSTRACT:
A liquid, pourable 100% active rheological additive especially useful for thickening non-aqueous compositions is described. The additive, which exists in a pourable form at up to a 100% as a rheologically active composition, exhibits excellent thickening efficiency for systems including inks, epoxies, polyesters, paints, greases and other systems, including ease of dispersibility, without adversely affecting gloss. The additive may operate by both an associative and a reaction mechanism to provide rheological viscosity properties to such systems, and is also similarly useful for aqueous systems.
One important aspect of the present invention relates to a liquid rheological additive composition comprising a reaction product obtained from the reaction of:
