RHEOTECH™ 3800 by Coatex (Arkema Group) is an APE-free, solvent-free aqueous dispersion of an acrylic copolymer. It is an associative, tin-free acrylic thickener designed to improve both the rheology and the color acceptance of water based formulations. Its outstanding effectiveness at medium shear rates allows to control very easily the perceived quality of paints during handling. It facilitates coating by roll or by brush, especially for finishing touches. It ensures safe additions of colorants in water-based formulations, limiting viscosity changes and rub-out issues. Provides improved sag/leveling and good water resistance. It can be used alone in high PVC formulations including matt & semi-matt paints, fillers and low cost formulations, at concentration between 0.1 and 0.6%. RHEOTECH™ 3800 has a shelf life of 6 months.
