Coatex Rheotech 3800 is a high-performance HASE acrylic associative thickener for water-based systems, developed by Gautier (Arkema Group). It works best at pH 8.5-9, providing strong medium-shear viscosity, balancing high-low shear rheology, preventing sagging and floating, reducing splatter, improving film fullness and tinting stability
Strong medium-shear thickening - Increases medium-shear viscosity, suitable for various construction scenarios
Anti-sagging & anti-floating - Prevents sagging and floating, ensuring uniform and stable film appearance
Splatter reduction - Increases medium-high shear viscosity, reducing roller splatter, improving construction efficiency
Eco-friendly compliance - Solvent-free, APEO-free and metal-free, meeting zero-VOC standards
Synergistic & economical - Compatible with various rheological additives, dosage 0.05%-0.6%, cost-effective
Matte/semi-matte coatings - Adapts to high PVC formulations, improving film fullness and application feel
High-gloss/silk paints - Optimizes leveling and gloss display, reducing construction defects
Tinting base paints - Ensures viscosity stability during tinting, helping uniform color presentation
Water-based architectural coatings - Adapts to alkaline systems, improving workability and stability
Zero-VOC eco-friendly coatings - Solvent-free formulation, meeting green production and application requirements
