Features Of Handa HDH6119 Waterborne Epoxy Curing Agent

  1. Low-VOC, water-based formulation compliant with stringent environmental regulations including EU REACH and China VOC Control Standards.

  2. Excellent compatibility with standard waterborne epoxy resins, enabling stable one-component or two-component systems.

  3. Fast ambient-cure capability with good early hardness development (≥80 Shore D after 24 h at 25°C/65% RH).

  4. Superior adhesion to concrete, steel, and aged coatings without primer requirement in many industrial maintenance applications.

  5. Good hydrolytic stability and extended pot life (>4 h at 25°C) when mixed with compatible epoxy dispersions.

Typical Applications Of Handa HDH6119 Waterborne Epoxy Curing Agent

  1. Waterborne epoxy floor coatings for pharmaceutical cleanrooms and food processing facilities.

  2. Corrosion-resistant protective coatings for interior steel structures in marine and offshore environments.

  3. High-performance concrete primers and topcoats in commercial infrastructure projects.

  4. Eco-friendly industrial maintenance coatings for machinery, tanks, and pipelines in regulated manufacturing plants.

  5. Low-emission hybrid epoxy-acrylic architectural coatings for interior walls and ceilings.
