Features Of Domestic HY-304D Polyurethane Associative Thickener

  1. Delivers excellent rheology control with strong sag resistance and leveling balance in waterborne systems.

  2. Provides outstanding compatibility with a broad range of latex polymers, surfactants, and co-thickeners.

  3. Offers high shear viscosity recovery and low spatter during application, enhancing brush/roller performance.

  4. Ensures long-term storage stability without viscosity drift or phase separation under ambient conditions.

  5. Non-ionic structure minimizes sensitivity to electrolytes and pH fluctuations typical in architectural coatings.

Typical Applications Of Domestic HY-304D Polyurethane Associative Thickener

  1. Interior and exterior architectural waterborne paints (flat to semi-gloss).

  2. Water-based primers and undercoats for wood and drywall substrates.

  3. Textured decorative coatings and texture plasters.

  4. Waterborne industrial maintenance coatings for metal and concrete.

  5. Low-VOC and zero-VOC compliant coating formulations.
