Superfine Silicon Dioxide:
It is made from hydrate silicon dioxide, and takes shape of super tiny white micro powder.
(a) Optimal flatting efficiency, precisely controlled process ensuring pore volume 2ml/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 (99.3% SiO2 and above), 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 compounds.
(e) Well dispersed: easily dispersed in any coatings, only require the common high sped stirs by approximate line-velocity1 5000r/min, and stirring 15-20 minutes.
(a) Advanced furniture coatings
(c) Leather / Synthetic Leather
(d) Thin film coating, such as synthetic and natural leather, decorative materials.
(3) Main technical data:
(a) SiO2 content: 99.3% min.
(b) Oil absorption (g/100g): 250-300
(c) Average particle size: centrifugal measure: 4 micron
(d) Ignition loss: ≤ 4%
(e) PH value (5% aqueous suspension): 6-8
(f) Surface treatment: no organic wax
(g) whiteness: ≥ 95
(4)Packing and storage:
(a) Packing: inner liner with polyester plastic film bag, surface layer with packing in multi-ply paper bag.
(b) Net weight: 15kg
(c) Storage: be requested storing in dry warehouse, no more than ten bags in stack height.
(d) The product possesses sucking dam strongly, tied bag closing after being used in order to affect quality.
