Nonionic Synthetic Associative thickener (NiSAT) for low VOC formulations latex paints and other waterborne coatings, solvent- and biocide free

RHEOLATE 644 IF is a 25% solids dispersion of a polyether urea polyurethane-based associative rheology modifier designed for use in waterborne paints and in low PVC systems.

RHEOLATE 644 IF provides efficient thickening in the high (ICI) and mid-shear viscosity (KU) ranges.

Tint-base pigmented systems benefit from the improved color acceptance and paint stability achieved with RHEOLATE 644 IF. RHEOLATE 644 IF is isothiazolinone-free and biocide-free and therefore contains no MIT, BIT or CIT.
