matting agent for hybrid powder coatings

jietonda® sa2165d is a synthetic resin based matting agent for hybrid powder coatings, which is designed for satisfying wide ranges of curing of requirements, having universal applicability to any polyester resins, whether fast-curing or not. the use of this product can provide ranges from 8-60%(60°) of low gloss, excellent flow and outstanding anti-yellowing.

1. typical properties

herein described to be typical properties and do not constitute specification limits.

2. characteristics
　 ● almost suitable for any 50/50 or 60/40 type hybrid polyester resins without remarkable selectivity, whether fast-curing or not.
　 ● can satisfy wide ranges of baking requirements to result in gloss-stable, excellent flow, and outstanding mechanical properties. the low temperature curing of 160℃/25min or 170℃/20min can be achieved depend on the particular fast-curing polyester used in formulation.
　 ● excellent overbaking stability.
　 ● eliminating effectively fingerprint on coating surface.
　 ● the recoatability and transfer-image properties of coatings are not influenced.

3. use method & levels
　 ● premix sa2165d with other components of the formula before extrusion.
　 ● the use level is 1- 4.5% based on total formulation by weight,depends on the gloss required.

4. package & storage
　 ● packaging with pe lined kraft paper bag. net weight 25kg per bag.
　 ● store in temperature between 2-32℃ or cool dry place. keep away from heat and fire.
　 ● from our experience,the shelf life of this product under above conditions is at least 2 years.

5. advisement
　 ● choose proper accelerator or catalyst to improve the impact resistance, but this will result in unexpected gloss up or worsen the surface leveling.
