I. Description:
XG610B is a kind of compound matting agent containing carboxyl, it reacts with epoxy as 1:2. The powder coatings formulated with XG610B has the excellent impact properties, flowing and yellowing resistance. The application of XG610B to the 50/50 or 60/40 resin could decrease the gloss effectively.

III. Application
1. The dosage of XG610B is around 3~5%. Smooth matt finishes with 60° gloss values ranging from 3% to 60% can be achieved with XG610B, esp. suitable for finishes gloss below 15%.
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’s not recomended to add catalyst such as imidazole to improve the impact properties, as which may lead to gloss and flowing change.
