RHEOVIS AS 1130
RHEOVIS AS 1130
RHEOVIS AS 1130 is an ideal rheology-control additive for water-based coatings. Using this product allows the formulation of coatings with an advantageous thixotropic behavior giving non-stringy formulations which are easy to apply over a wide range of speeds and/or processes. Such formulations are ideally suitable for airless spray applications.
RHEOVIS® AS 1130 is a derivative of a family of highly effective rheology-control thickeners for a wide range of water-based coatings. It is an acrylic copolymer emulsion in water. The polymer provides the rheological control effect through extensive swelling of the high molecular weight polymer in alkali, in the presence of water.
BASF also offers the rheology-control additives RHEOVIS® 132, RHEOVIS® 112, and RHEOVIS® 152 with more Newtonian properties.
As synthetically derived products, RHEOVIS AS 1130 is less susceptible to microbiological attack than derivatives of cellulose. Consequently, the paint formulator can substantially reduce the level of biocide leading to a broader area of application.
