Features Of Huntsman Powder Coating Latent Curing Agent Accelerator DY 9577

  1. Enables precise latency at ambient temperatures, ensuring excellent storage stability in powder coating formulations.

  2. Activates rapidly during standard curing cycles (180–200 °C), delivering efficient crosslinking with epoxy and hybrid resin systems.

  3. Improves edge coverage and film uniformity without compromising gloss or surface smoothness.

  4. Compatible with conventional electrostatic spray application equipment and standard powder manufacturing processes.

  5. Low volatility and non-hygroscopic nature support consistent batch-to-batch performance and extended shelf life.

Typical Applications Of Huntsman Powder Coating Latent Curing Agent Accelerator DY 9577

  1. Architectural aluminum profiles for curtain walls and window frames.

  2. Automotive under-hood components requiring high thermal and chemical resistance.

  3. Appliance housings including ovens, refrigerators, and washing machines.

  4. Industrial metal furniture and office equipment with demanding aesthetic and durability requirements.

  5. General-purpose industrial coatings for steel and aluminum substrates in corrosion-prone environments.
