Coatex Rheotech 4800 Thickener

Coatex Rheotech 4800 is a high-performance HASE acrylic associative thickener for water-based coatings and adhesives, developed by Gautier (Arkema Group). It works best at pH 8.5-9, providing strong low-medium shear viscosity, efficiently increasing yield value, preventing sagging, floating and water separation, optimizing leveling and application feel, giving coatings a creamy appearance, solvent-free

Features Of Coatex Rheotech 4800 Thickener

  1. Strong low-medium shear thickening - Efficiently increases low-medium shear viscosity and yield value, suitable for high PVC systems

  2. Tinting stability & anti-floating - Prevents viscosity drop after tinting, eliminates floating and water separation

  3. Excellent appearance & feel - Gives coatings a creamy appearance, optimizes leveling and application feel

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

  5. Synergistic & economical - Compatible with various rheological additives, dosage 0.01%-0.5%, cost-effectiv

Typical Applications Of Coatex Rheotech 4800 Thickener

  1. High PVC matte coatings - Adapts to low-cost formulations, improving film fullness and application feel

  2. Thick-film coatings/wall powders - Prevents sagging and settling, ensuring construction quality

  3. Pressure-sensitive adhesives - Regulates rheology, improving bonding stability and workability

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

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