Coatex Coapur 2025 is a HEUR associative polyurethane thickener for water-based systems, developed by Gautier (Arkema Group). It shows Newtonian rheology, strongly increasing high-shear viscosity, balancing rheological properties, reducing splatter, optimizing leveling and film fullness, eliminating brush marks, solvent-free, APEO-free, suitable for zero-VOC formulations
Strong high-shear thickening - Strongly increases high-shear viscosity, suitable for Newtonian rheological requirements
Splatter reduction & leveling optimization - Reduces construction splatter, optimizes leveling, eliminates brush marks
High reactivity & wide adaptability - High reactivity with various resins, suitable for multi-system formulations
Eco-friendly compliance - Solvent-free, APEO-free, meeting zero-VOC standards
Synergistic & economical - Compatible with various rheological additives, dosage 0.1%-1%, cost-effectiv
High-gloss/silk paints - Increases high-shear viscosity, optimizing leveling and gloss display
Matte coatings - Cooperates with other thickeners, ensuring uniform and stable film appearance
Varnishes/topcoats - Increases high-shear viscosity, optimizing leveling and film fullness
Water-based wood coatings - Adapts to water-based systems, improving workability and film texture
Zero-VOC eco-friendly coatings - Solvent-free formulation, meeting green production and application requirements
