Rheovis® HS 1212

Rheovis® HS 1212 by BASF is a hydrophobic modified acrylic swellable copolymer emulsion (HASE) in water. Acts as a mid-shear thickener and rheology-control agent. Suitable for water based coatings to increase viscosity in the mid-shear range. Provides the rheology–control effect through extensive swelling of the high-molecular-weight polymer in combination with a hydrophobic component in alkali, in the presence of water. This leads to superior coatings-build up and low spattering, ideal for a broad range of matt to semi-gloss interior and exterior coatings. Rheovis® HS 1212 improves flow and is most effective between pH 8 to 10. Typical dosage is between 1.0 to 3.5 percent.
