Coatex Rheotech 2800 Thickener

Coatex Rheotech 2800 is a high-performance HASE acrylic associative thickener for water-based systems, developed by Gautier (Arkema Group). It combines acrylic thickeners' stability with polyurethane thickeners' leveling, works best at pH>8, providing near-Newtonian rheology, balancing high-medium-low shear viscosities, preventing sagging and floating

Features Of Coatex Rheotech 2800 Thickener

  1. Balanced rheology - Balances high, medium and low shear viscosities, 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, reduces 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 0.1%-1%, cost-effective

Typical Applications Of Coatex Rheotech 2800 Thickener

  1. High-end matte coatings - Suitable for single-coat matte latex paints, improving film fullness and application feel

  2. High-gloss/silk/semi-matte 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 high-low PVC formulations, improving workability and stability

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