1)Features :a) Optimal flatting efficiency, precisely controlled process ensuring pore volume 1.8ml/g for consistent performanceb) Easy adding: in the production of the coatings, it can be easily added in any processc) 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 organice) 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.

  2) Applications:a) Advanced furniture coatingsb)coil coatingsc) Leather / Synthetic Leather

d) Thin film coating, such as synthetic and natural leather, decorative materials

e) PU coating , AC coating , Ink, NC coating

f) coil coating, industrial coating

3) Main technicaldata : a) SiO2 content: 99.3% min. b) Oil absorption (g/100g): 315c) Average particle size: 3 micrond) Ignition loss: 8%e) PH value (5% aqueous suspension): 7f) Surface treatment: non-wax treatment

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