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
Strong low-medium shear thickening - Efficiently increases low-medium shear viscosity and yield value, suitable for high PVC systems
Tinting stability & anti-floating - Prevents viscosity drop after tinting, eliminates floating and water separation
Excellent appearance & feel - Gives coatings a creamy appearance, optimizes leveling and application feel
Eco-friendly compliance - Solvent-free, APEO-free and metal-free, meeting zero-VOC standards
Synergistic & economical - Compatible with various rheological additives, dosage 0.01%-0.5%, cost-effectiv
High PVC matte coatings - Adapts to low-cost formulations, improving film fullness and application feel
Thick-film coatings/wall powders - Prevents sagging and settling, ensuring construction quality
Pressure-sensitive adhesives - Regulates rheology, improving bonding stability and workability
Tinting base paints - Ensures viscosity stability during tinting, helping uniform color presentation
Zero-VOC eco-friendly coatings - Solvent-free formulation, meeting green production and application requirements
