  • Product Detail

The Curing accelerate agent KC5230 is a specific onium salt catalyst, it could be used as carboxyl group-containing polyester resin inner-catalyst or the curing accelerator to reduce the curing temperature or curing time of powder coatings.

1. Technical Parameters

Ø  Ingredient: Onium salt

Ø  Appearance: White crystal

Ø  Content: ≥98.5%

Ø  Mp: 205℃-215℃

2. Product Properties

Ø  The Curing accelerate agent is suitable for outdoor polyester/TGIC powder coating.

Ø  Compared to the quaternary ammonium or phosphonium salt curing accelerator, this product has a better curing effect, thermal stability.

Ø  Low amount of the KC5230 could meet the curable requirement of generally powder coatings.

Ø  This product is a free-flowing, non-hygroscopic crystalline solid, and easy to be used.
