Description
a) Optimal flatting efficiency, precisely controlled process ensuring pore volume 1.8ml/g for consistent performance.
b) Easy adding: in the production of the coatings, it can be easily added in any process.
c) High film clarity: extremely high purity (99% SiO2 and above), refractive index 1.46 comparable to that of most resins.
It makes silica invisible in polymer films and clear lacquers
d) Optimal suspension: no hard sedimentation through long time reserving since it is treated by organic
e) Well dispersed: easily dispersed in any coatings, only require the common high sped stirs by approximate line-velocity 5m/s, and stirring 15 - 20 minutes, typical hegman value 15 - 25um.

Notice:
Although commonly it can not damage the flatting grains in the dispersion process because of the "excess" grinding, it may reduce the flatting effect and increase the viscosity if it is ball milled or tri-roller milled for a long time.
