ROHAGIT SD 9523: thickener, pH activated. ROHAGIT SD 9523 is an anionic water based dispersion of a butadiene acrylate copolymer.

Prevents the sedimentation of pigments in paints. Improves the pigment-wetting during dispersion. In many paint systems the floating of pigments in pigment-mixtures is prevented. The tendency to flow off is reduced and the covering of edges is improved. Suggested for all solvent based and solvent-free paint systems. ADDITOL XL 270 is usually compatible with solvent based and solvent-free binders. It prevents the sedimentation of pigments in paints. The rheological character of paints is improved. The tendency to flow on vertical surfaces is reduced. The edges of substrates are better covered in case of dipping application. The drying of oxidatively drying systems is not influenced by ADDITOL XL 270, if the appropriated dose is used. Also the efficiency of siccatives in paints, stored for a long time, is not reduced using ADDITOL XL 270. Considering anti-corrosive paints, there is no corrosion-resistance loss by using ADDITOL XL 270. It is recommended to be used for the activating of organophile bentonites and it improves the effect of pyrogene silica.

CRAYVALLAC LA-350 is a modified urea dissolved in DMSO and is a pourable liquid rheology modifier for post addition to water-based coatings such as water-dilutable alkyds and acrylic emulsions.

CRAYVALLAC LA250 is a modified urea dissolved in DMSO and is a pourable liquid rheology modifier for post addition to low polarity solvent based coatings.
