1. The document provides information on various interior and exterior matting agents (M-20, M-21, M-30, M-60, M-70) for use in polyester epoxy hybrid and TGIC-based powder coatings. 2. The matting agents are acrylic resin and catalyst powders that provide different gloss levels when used between 1-5% of the total formulation weight. 3. They offer benefits like stable matting performance, anti-yellowing properties, and compatibility with common polyester resin types for powder coatings.

3. Compared with 68 series matting hardener, M-20 has better anti-yellowing and scratch resistance properties.
4. Good gloss stability after twice extruded.
5. M-20 can adopt toaster or cold furnace to bake due to small sensitivity of furnace temperature.
6. Chemical matting agent, good storage stability. It reacts with epoxy as 1:2.3.
7. M-20 is suitable for almost 50/50 or 60/40 type hybrid polyester resins without remarkable selectivity.
8. Heavy metal contents of this product conforms to the EU RoHS standard.
Usage method & level
Premix M-20 with other material and co-extrude. The dosage is 1-5% by total weight of formulation.
The more of the dosage, the lower for the gloss.
