Coatex Coapur 830W Thickener

Coatex Coapur 830W is a solvent-free, APEO-free non-ionic water-based polyurethane associative thickener by Gautier (Arkema Group) for waterborne systems. It efficiently boosts medium-high shear viscosity, optimizing leveling and application feel, preventing sagging, settling and floating, ideal for matte, semi-gloss, anti-corrosion coatings, solvent-free & zero-VOC formulations

Features Of Coatex Coapur 830W Thickener

  1. Strong medium-high shear thickening - Efficiently increases medium-high shear viscosity, suitable for low-PVC systems anti-sagging

  2. Good synergies & wide compatibility - Compatible with acrylic/cellulose ether thickeners, suitable for various formulations

  3. Excellent application & cost-saving - Improves leveling and application feel, reduces coating times and waste

  4. Eco-friendly compliance - Solvent-free, APEO-free, meeting FDA & BGVV standards

  5. High concentration & economical - 30% high concentration, dosage 0.05%-1.0%, cost-effective

Typical Applications Of Coatex Coapur 830W Thickener

  1. Semi-gloss/silk-gloss latex paints - Increases medium-high shear viscosity, optimizing leveling and application feel

  2. Matte latex paints - Improves coating thickness and leveling, reduces sagging and settling

  3. Anti-corrosion coatings - Optimizes rheology and anti-settling, suitable for solvent-free formulations

  4. Water-based wood coatings - Improves color development and workability, enhancing film texture

  5. High-PVC flat latex paints - Synergizes with low-shear thickeners, improving water resistance and scratch resistance
