1.Profile:
1) Optimal flatting efficiency: precisely controlled process ensuring pore
volume 1.8ml/g for consistent performance
2) Easy adding: in the production of the coatings, it can be easily added
in any process
3) 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
4) Optimal suspension: no hard sedimentation through long time reserving
since it is treated by organic
5) 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
2. Main reference:
a) SiO2 content: 99% min.
b) Oil absorption (g/100g): 280
c) Average particle size (centrifugal measure): 3 micron
d) Laser measure: 6 micron
e) Ignition loss: 4%
f) PH (5% aqueous suspension): 6 - 7
g) Surface treatment: organic wax
Packing:
1) Inner liner with polyester plastic film bag, surface layer with packing
in polypropylene bag
2) Net weighty: 5kg
3) Storing: be requested storing in dry warehouse, no more than ten bags
in stack height. The product possess sucking dam strongly, tied bag
closing after being used in order to affect quality
3.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.
