Coatex Rheotech 3800 Thickener

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

Features Of Coatex Rheotech 3800 Thickener

  1. Strong medium-shear thickening - Increases medium-shear viscosity, suitable for various construction scenarios

  2. Anti-sagging & anti-floating - Prevents sagging and floating, ensuring uniform and stable film appearance

  3. Splatter reduction - Increases medium-high shear viscosity, reducing roller splatter, improving construction efficiency

  4. Eco-friendly compliance - Solvent-free, APEO-free and metal-free, meeting zero-VOC standards

  5. Synergistic & economical - Compatible with various rheological additives, dosage 0.05%-0.6%, cost-effective

Typical Applications Of Coatex Rheotech 3800 Thickener

  1. Matte/semi-matte coatings - Adapts to high PVC formulations, improving film fullness and application feel

  2. High-gloss/silk paints - Optimizes leveling and gloss display, reducing construction defects

  3. Tinting base paints - Ensures viscosity stability during tinting, helping uniform color presentation

  4. Water-based architectural coatings - Adapts to alkaline systems, improving workability and stability

  5. Zero-VOC eco-friendly coatings - Solvent-free formulation, meeting green production and application requirements
