Polymeric Curing Accelerator KC5230

It can promote the ring-opening reaction of epoxy and carboxyl groups, with very low dosage, and antiyellowing. It can reduce the curing temperature of the system, significantly improve the incomplete curing of the system, improve the impact resistance of the coating film, increase the adhesion of the substrate, and the anti-yellowing temperature can reach 230 ℃.

Curing accelerator KC5230 is a special onium salt catalyst that can be used as an internal catalyst for carboxyl polyester resins or as a curing accelerator to reduce the curing temperature or shorten the curing time of powder coatings.

1)Typical Properties:

Accelerate ring-opening polymerization of an epoxy group and carboxyl: Superb anti-yellowing in 230C with low dosage; Anti-cracking;

Impact resistance;

Lower the curing temperature/shorten the curing time, Improve the curing reaction.

2)Recommended Use:

KC5230 is used in powder coatings based on polyester/TGIC

3)Special Features and Benefits

Better curing effect and thermal stability than QAS. Easy to use, free to flow, and humidity resistant.

Cost performance: Catalyze the curing reaction with a low dosage

4)Recommended Levels

0.05-0.1 % additive (as supplied) based on the total formulation when extruding with all formulation components.

The above-recommended levels can be used for orientation

Optimal levels are determined through a series of laboratory tests.
