?etailed Product Description

Place of Origin:China Hunan Brand Name:Hongsheng?
?odel Number:SA-220 Purity:99.3
?AS No.:112926008
?/p>

Certification: ISO ISO9001 ,ROHS
Features :
1) Profile:white micro powder
a) Optimal flatting efficiency, precisely controlled process ensuring pore
volume 1.8ml/g for consistent performance
b) Optimal flatting efficiency: 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
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.
2) Applications:
a) Advanced furniture coatings
b)coil coatings
c) Leather / Synthetic Leather
d) Thin film coating, such as synthetic and natural leather, decorative
materials
3) Main technicaldata :
a) SiO2 content: 99.3% min.
b) Oil absorption (g/100g): 280-330
c) Average particle size: centrifugal measure: 2 micron
d) Ignition loss: 4%
e) PH value (5% aqueous suspension): 7
f) Surface treatment: no organic wax
g)whiteness:95

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.
