La description

MIN-U-SIL fine ground silica is a natural crystal quartz product which exploited by U.S.SILICA. It has high purity（the content ofSIO2more than *9.5%），even particle size distribution，high whiteness and brightness，low moisture content good characteristics. It is especially suitable for applications which require improving the hardness of paint films and reinforce. It can be instead of the import titanium powder to reduce the cost.
 
According to the particle sizes it has 5 types：5 u，*0 u，*5 u，*0 u，*0 u
Physical properties：

1. Excellent particle separation, the use of statistical procedure to control the production process to insure the high quality and stability.
2. High purity, it has neutral and chemical inertness properties which is easy for formulation.
3. Nature crystal particle has excellent abrasive resistance and rigidity
4. Lower specific surface area to reduce the resin to have high additives and low viscosity
5. Good processability、small shrinkage、smalll thermal expansion、acid alkaline resistance、solvent insulation and mechanical properties.
