Features Of HARDENER HV953U CI Curing Agent

  1. Aliphatic polyamine-based curing agent offering low viscosity and excellent compatibility with epoxy resins.

  2. Provides fast ambient-cure kinetics without requiring elevated temperature post-curing.

  3. Delivers outstanding chemical resistance, particularly to alkalis and solvents, in cured epoxy systems.

  4. Low color and minimal odor — suitable for high-clarity and indoor applications.

  5. Non-hazardous classification per GHS: not classified as acutely toxic, skin sensitizer, or respiratory sensitizer.

Typical Applications Of HARDENER HV953U CI Curing Agent

  1. High-performance industrial flooring coatings (e.g., seamless epoxy terrazzo and self-leveling systems).

  2. Chemical-resistant tank linings and secondary containment systems.

  3. Electrical insulation potting and encapsulation for transformers and busbars.

  4. Heavy-duty protective coatings for steel infrastructure in marine and offshore environments.

  5. Adhesives and structural bonding formulations for composites and metal substrates.
