CRAYVALLAC® SL
Arkema Rheology & Specialty Additives
CRAYVALLAC® SL is a high-performance micronized amide wax rheology modifier designed for the high-temperature manufacture of moisture curing methoxy silane systems, where processing temperatures typically lie within the range of 90 – 115°C. CRAYVALLAC® SL particles are converted to an interacting network of crystalline fibers. It is this network that gives rise to the shear thinning rheology. This shear thinning characteristic provides for a low viscosity at the shear rates associated with application by extrusion, and a very high viscosity under the low shear rates experienced after application. The net result is ease of application followed by excellent sag and slump resistance.

Ecodis™ 40
Ecodis™ 40 is a sodium neutralized polyacrylate dispersing agent for water-based systems. It ensures the complete dispersion of extenders and inorganic pigments at high solids contents in systems showing medium to high PVC (Pigment Volume Concentration). Very versatile and suitable for titanium dixide, Kaolin and calcium cabonates. Besides dispersion paints, the main applications are in adhesives & sealants.
Ecodis™ 80
Ecodis™ 80 is an ammonium neutralized polyacrylate dispersing agent for water-based systems. It ensures the complete dispersion of extenders and inorganic pigments at high solids contents in systems showing medium to high PVC (Pigment Volume Concentration). Very versatile and suitable for titanium dixide, Kaolin and calcium cabonates. Besides dispersion paints, the main applications for Ecodis™ 80 are in adhesives and wall paper pastes.
Ecodis™ C 30
Ecodis™ C 30 has been especially developed as a lighter-colored version of Ecodis™ P 30 with limited color evolution upon storage. It ensures the complete dispersion of extenders and inorganic pigments at high solids contents in systems showing medium to high PVC.
Ecodis™ N
Ecodis™ N is a cost effective dispersant recommended for use in matt dispersion paints. It contributes to shorten the time needed for a proper incorporation of usual fillers and pigments (calcium carbonate, titanium dioxide) even when a high concentration in solids is required. Ecodis™ N also helps to ensure long term viscosity stability to dispersion paints showing a high solids content and/or a high PVC (pigment volumic concentration).
