I. Description:

XG610A is a kind of compound matting agent containing carboxyl, it reacts with epoxy as 1:2.7. The powder coatings formulated with XG610Ahas the excellent impact properties, flowing and yellowing resistance. The application of XG610Ato the 50/50 or 60/40 resin could decrease the gloss effectively.

III. Application

1. The amount of XG610Ain the formulation is around 1~6%. Smooth matt finishes with 60° gloss values ranging from 3% to 60% can be achieved with XG610A.

2. As the degree of gloss is connected with the resin used, the formulation should be tested in the lab first. Coatings formulated with DSM P6060(4:6), ShenJian 3#B(5:5) 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. Baking condition:190/15min or200/12min.

Under above condition the gloss and impact properties can be guaranteed.
