Curing accelerator KC5210 is a special quaternary ammonium salt catalyst that can be used as an internal catalyst for carboxy polyester resins or as a curing accelerator to reduce the curing temperature or shorten the curing time of powder coatings.
Accelerate ring-opening polymerization of an epoxy group and carboxyl; Superb anti-yellowing with low dosage; Lower the curing temperature; Improve the curing reaction; Impact resistance.
2)Special Features and Benefits
The additive improves the curing effect. KC5210 has superb thermal stability and yellowing resistance.
Cost performance: Catalyze the curing reaction with low dosage.
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.
4)Incorporation and Processing Instructions
The product should be mixed with the resin, hardener, pigments, and other additives using a high-speed mixer and extruded along with all components.
5)Packaging and storage
Polyethylene lined kraft paper bags, net weight 25kg per bag. The packaging is sealed, stored in a cool and dry place, and the shelf life is at least 1 year.
