Detailed Product Description1) Profile:a) Optimal flatting efficiency, precisely controlled process ensuring pore volume 1.8m-2.0l/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), refractive index 1.46 comparable to that of most resins. It makes silica invisible in polymer films and clear lacquersd) 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-velocity 5m/s, and stirring 15 - 20 minutes, typical hegman value 15 - 25μm

2) Applications:a) Advanced furniture coatingsb) General industrial coatingsc) Decorative paint and othersd) Thin film coating, such as synthetic and natural leather, decorative materials

3) Main reference: a) SiO2 content: 99.3% min. b) Oil absorption (g/100g):230-250c) Average particle size: centrifugal measure: 5-5.5 micrond)laser measure: 4micron e) Ignition loss: 5%f) PH value (5% aqueous suspension): 6-7 g) Surface treatment:noNotice: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.
