RHEOVIS® AS 1237 is a low- to medium-effective non-associative rheology modifier, ideal in mat and semi-mat emulsion paint systems with a pigment volume concentration of 25 – 50%.

It shows excellent color stability in tinted systems, also providing good ant-sag and anti-spatter properties.

RHEOVIS® AS 1237 is a formulation based on an acrylic copolymer. The polymer provides the rheology-control effect through extensive swelling of the high-molecular-weight polymer in alkali, in the presence of water.
