Rheology modifiers

RHEOVIS®, ATTAGEL®, ATTAFLOW® and EFKA® rheology modifiers for water-based, solvent-based, and solvent-free formulations

Our synthetic rheology modifiers include non-ionic associative (HEUR / HMPE), anionic associative (HASE) and non-associative thickener (ASE) technologies. Our focus is on highly efficient additives for water-based systems. Our rheology modifiers also provide additional functionalities like wetting properties and health or environmental benefits such as suitability for formulations free of VOCs, odors, APEOs and heavy metals.

Rheology modifiers from BASF effectively reduce dripping and spattering of paints during roller or brush application. Sag resistance is improved by a rapid but controlled viscosity increase after application. They also reliably prevent sedimentation of pigments during transport and storage of the paints.

At BASF, you will find experts who understand your specific needs and are glad to support you in finding the right rheology modifiers for your formulations.

Rheology modifiers for water-based systems

ATTAGEL 40Inert powdered gelling grade of attapulgite clay. It is finely pulverized to effectively form colloidal gels in ionic and non-ionic aqueous solutions to provide thixotropic thickening and suspension.
RHEOVIS PU 1251Extremely efficient, solvent-free non-ionic, associative rheology modifier designed to improve dry coating performance and appearance while improving application properties of latex based coatings and adhesives.
RHEOVIS PU 1341Excellent low VOC high-shear rheology modifier with low odor, and imparts excellent flow.
RHEOVIS HS 1152Hydrophobically modified alkali swellable emulsion (HASE) and, upon neutralization with a base, enhances low-shear rheology in water-based coating systems.
RHEOVIS AS 1130Alkali swellable emulsion (ASE) that, upon neutralization with a base, imparts strong shear thinning characteristics in water-based coating systems.
PHARMASORBColloidal activated attapulgite clay sorbent.

Rheology modifiers for solvent based systems

EFKA RM 1463Pre-activated polyamide wax thickener; excellent anti-sagging and anti-settling properties for solvent based industrial, architectural, heavy duty and marine coatings.
EFKA RM 1469Rheology modifier for solvent-based systems. Recommended in the application of pigment preparations as well as in clear or topcoats which require maximum gloss.
EFKA RM 1506Anti-settling and anti-hard caking agent for solvent based systems; hard paste type of polyethylene wax dispersed in xylene; well suited for most solvent-based systems in dipping, spraying and aerosol applications.
EFKA RM 1900Rheology modifier that provides excellent sag resistance for non-aqueous formulations with higher temperature stability.
EFKA RM 1920Rheology modifier that provides excellent sag resistance for non-aqueous formulations with standard thixotropy.
EFKA RM 1965Rheology modifier that prevents settling of pigments in solvent-based coatings by developing a more shear-thinning rheological behavior; prevents formation of hard pigment sedimentation.

Rheology modifiers for solvent free systems

EFKA RM 1506Anti-settling and anti-hard caking agent for solvent based systems; hard paste type of polyethylene wax dispersed in xylene; well suited for most solvent-based systems in dipping, spraying and aerosol applications.
EFKA RM 1900Rheology modifier that provides excellent sag resistance for non-aqueous formulations with higher temperature stability.
EFKA RM 1920Rheology modifier that provides excellent sag resistance for non-aqueous formulations with standard thixotropy.
EFKA RM 1965Rheology modifier that prevents settling of pigments in solvent-based coatings by developing a more shear-thinning rheological behavior; prevents formation of hard pigment sedimentation.
