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. Temperature should be controlled to be below 50℃.
3. Low viscosity. It can be used for high viscosity system.
It is main applied in coil coating, Industrial Paint.
