One: Physical properties:

High purity alumina particles, sapphire crystal growing raw material with high purity alumina powder fine processing, is my company independent research and development. With high purity, high density, the characteristics of can provide different specifications of the purity of 99.996 to 99.999%, density of 3.0 3.6 g/cm high purity alumina pellets grain of material.with the characteristics of high purity, even granule, good fluidity, high speed of crystal growth, etc. It is widely used in the lava sapphire crystals, catalysts, polishing materials, ceramics, three-color phosphors, long afterglow luminescent powder, etc.


A: the lens coating used for the surface:

1. Have stronger resistance to reflect, to light the permeability will increase, the wearer feel less glare, see things much more vivid and bright,

2. No reflections, and should not wear away, a good cleaning

3. And can effectively prevent ultraviolet or computer radiation (because the lens has two kinds of film, is a kind of uv protection membrane, membrane is a kind of computer radiation proof

4. How to identify whether there is a coating, light source, if you see a purple or green reflective, said with the reflection of the protective film,

B: used glass surface coating

1, make the surface for a long time in a new state.

2, make the surface will not easily be contaminated with foreign materials or influence.

3, when cleaning surfaces can easily put some dirt on the surface of the object is qualitative

C: used car surface coating

1. The automobile coating have the effect that prevent the surface oxidation and aging

2. Can greatly improve the car paint surface varnish clarity, made the car paint looks more brilliant.

3. The corrosion resistance

4. High temperature resistant

5. Scratch resistant

6. Easy to clean

7. Super durable strong toughness and ductility

8. Super water environmental protection use environmental protection material, its oxidation

9. Super wate



1.All products are manufactured by advanced devices and follow international standards like ISO9000 , ISO14000 and RoHS which can ensure the purity , finished products will only be shipped after being passed OQC department's strict inspection

2.Free sample is available and customized products are welcome

3.Fast delivery and good after –sale service
