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. Good transparency performance. After scientific arrangement, the refractive index is close to the refractive index of film-forming resin, which avoids the possible white fog of Matt transparent paint.
10kg/bag; Store in Dry ventilation place.
