Features Of Arkema Coapur 975W Carboxylated Polymer Thickener

  1. High-efficiency rheology modifier delivering strong pseudoplastic behavior and excellent viscosity build in aqueous systems.

  2. Carboxylated polymer structure ensures robust performance across a broad pH range (pH 4–10) without requiring neutralization.

  3. Provides outstanding shear-thinning properties, enabling easy application and leveling while maintaining sag resistance.

  4. Compatible with common surfactants, co-thickeners, and biocides used in industrial and architectural formulations.

  5. Low VOC and APEO-free, supporting compliance with stringent environmental and regulatory standards.

Typical Applications Of Arkema Coapur 975W Carboxylated Polymer Thickener

  1. Architectural waterborne paints (interior and exterior flat, satin, and semi-gloss formulations).

  2. Industrial maintenance coatings including primers, topcoats, and anti-corrosive systems.

  3. Water-based adhesives and construction sealants requiring controlled flow and open time.

  4. Textile printing pastes where stable viscosity and pigment dispersion are critical.

  5. Tile grouts and cementitious repair mortars for improved workability and water retention.
