I. Description:
XG610C-2 is a compound matting agent containing carboxyl, it reacts with epoxy as 1:2.2. The powder coatings formulated with XG610C-2 has the excellent impact properties, flowing and yellowing resistance. The application of XG610C-2 to the 50/50, 60/40 resin can decrease the gloss effectively.
XG610C-2 is especially suitable for obtaining 10~40 gloss finishes.

III. Application
1. The dosage of XG610C-2 is around 1~2%.
2. As gloss is related to the resin used, the formulation should be tested in the lab first. Sino-French P5086(5:5), ShenJian 5#A(4:6) can provide lower gloss and good impact properties.
3. It is not recommended to add catalysts such as imidazole in the formula to improve the impact properties, as which may lead to gloss and flowing change.
4. XG610C-2 can help to obtain low gloss, good flow and mechanical property finishes with less resin.
4. Baking condition: 190℃/15min or200℃/12min, under which gloss and impact properties is guaranteed.
IV. Suggested formulation: (Baking condition:190℃/15min.)
