Contact our experts
Product overview
Rheocarb™ 121 maintains particles (pigments and latex) dispersion with full gloss potential and strong thickening power. It provides a good water retention and is a strong OBA carrier. It allows the reduction of drying and calendering costs and of coating colors costs (use of cost efficient pigments, binders and other additives). Use in top coats made of slightly coarser pigments and lower solids content and film press coating in place of starch and in order to reduce elasticity and the risks of misting.
