1. High matting efficiency because its particle size distribution is in the range to effect excellent matting efficiency.
2. Easy dispersing. Normally it can be dispersed completely under mix speed 1200rpm (5-6m/S) for 10-15 minutes. Temperatures should be controlled to be below 50℃.
3. High transparent, and foggy appearance can be avoided in vanish.
4. Can be applied both in solvent system and aqueous system.
5. Low oil absorption.
