MT-6500 is a kind of organic surface treated, and easily dispersible amorphous silica matting agent for applications in both solvent system and aqueous system. It is suitable for most of paint (except leather coatings) and inks, including photocureable coatings and elastic paint.
MT-6500 is improved from our MT-6112. Compared with MT-6112, MT-6500 is of lower oil absorption, better transparency, easier to be dispersed and higher matting efficiency.
MT-6500 can be added in paint formulation with high resin content.

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. High transparent, and foggy appearance can be avoid in vanish.
4. Can be applied in both in solvent system and aqueous system.
5. MT-6500 has good thermal stability.
