A liquid, pourable 100% active rheological additive especially useful for thickeningnorganic compositions which in one aspect comprises an active hydrogen containing compound suchnas a polyol, one or more polycarboxylic acids or isocynanates, and a functional chain ending unit.nThe additive, which exists in a pourable, pumpable form at up to a 100% as a rheologically activencomposition, exhibits excellent thickening efficiency for systems including inks, epoxies, polyesters,npaints, greases and other systems, including ease of dispersibility, without adversely affecting gloss.nThe additive may operate by both an associative and a reaction mechanism to provide rheologicalnviscosity properties to such systems, and is also similarly useful for aqueous systems. |
