Coatex Coapur 830W is a solvent-free, APEO-free non-ionic water-based polyurethane associative thickener by Gautier (Arkema Group) for waterborne systems. It efficiently boosts medium-high shear viscosity, optimizing leveling and application feel, preventing sagging, settling and floating, ideal for matte, semi-gloss, anti-corrosion coatings, solvent-free & zero-VOC formulations
Strong medium-high shear thickening - Efficiently increases medium-high shear viscosity, suitable for low-PVC systems anti-sagging
Good synergies & wide compatibility - Compatible with acrylic/cellulose ether thickeners, suitable for various formulations
Excellent application & cost-saving - Improves leveling and application feel, reduces coating times and waste
Eco-friendly compliance - Solvent-free, APEO-free, meeting FDA & BGVV standards
High concentration & economical - 30% high concentration, dosage 0.05%-1.0%, cost-effective
Semi-gloss/silk-gloss latex paints - Increases medium-high shear viscosity, optimizing leveling and application feel
Matte latex paints - Improves coating thickness and leveling, reduces sagging and settling
Anti-corrosion coatings - Optimizes rheology and anti-settling, suitable for solvent-free formulations
Water-based wood coatings - Improves color development and workability, enhancing film texture
High-PVC flat latex paints - Synergizes with low-shear thickeners, improving water resistance and scratch resistance
