Abstract
Five commercial polyacrylate samples were used to study their effects on viscosity, water holding, and binder migration under non-pressure conditions. The polyacrylates used were different in acid level, degree of crosslinking, and type of polymer (copolymer and terpolymer). A series of coatings was prepared using a number two clay and three styrene-butadiene latexes of similar particle size and T⋁g but different degrees of carboxylation, then the polyacrylates were added at several levels. The coatings were evaluated for rheological properties, water loss rate and binder migration. The results show that with increasing amounts of polyacrylates, the viscosity increased and the water loss rate and the binder migration decreased. The high acid level polyacrylate gave higher viscosity and water holding, and lower binder migration as compared to low acid level polyacrylate. No significant effect of type of polymer on the water loss rate and binder migration was found. The highest acid level latex provided lowest viscosity, and highest binder migration.
