Rheovis AS 1130 is a derivative of a family of highly effective rheology-control thickeners for a wide range of water-based coatings.
Rheovis AS 1130 provides the rheological control effect through extensive swelling of the high molecular weight polymer in alkali, in the presence of water.
Use Rheovis AS 1130 allows 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 suited for airless spray applications for industrial and automotive formulations, and it can also be used in pigment and filler slurries.
Rheovis AS 1130 offers additional performance highlights such as high shear thinning and anti-sagging and settling.

Rheovis AS 1130 is resistant to microbiological attack.
Applications of Rheovis AS 1130:
Rheovis AS 1130 is the ideal rheology-control additive for water-based coatings.
Using Rheovis AS 1130 allows 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 an alkali swellable emulsion type thickener (ASE).
Rheovis AS 1130 is optimally effective in the pH range of 7.5 to 10.5.
As a synthetically derived product, Rheovis AS 1130 is less susceptible to microbiological attack than derivatives of cellulose.
Consequently, paint formulators can substantially reduce the level of biocide leading to a broader area of application.
Rheovis AS 1130 is an alkali swellable emulsion (ASE) that, upon neutralization with a base, imparts strong shear thinning characteristics in water-based coating systems.
This pseudoplastic nature gives formulators a cost effective way to improve the anti-settling and sag resistance without compromising leveling and film build.
Rheovis AS 1130 should be considered for maximum anti-settling and sag resistance.
Product highlights of Rheovis AS 1130:
-Strong shear thinning effect
-Improves anti-settling and sag resistance
-Excellent spray properties
-Good viscosity stability after tinting
-Low VOC content
-APEO-free
-Heavy-metals-free (e.g. organic tin compounds)
-Solvent-free
-Very efficient at low dosage

Formulation guideline:
1.0 – 3.5 % on total formulation
The amount required for optimum performance should be determined in trials covering a concentration range.
Rheovis AS 1130 should preferably be added at the final stage of manufacturing of the formulation.
The liquid form of Rheovis AS 1130 makes post addition comfortable.
As a positive side effect, the post addition offers flexibility for viscosity adjustment from batch to batch.
