5.Usage instruction

1. Usage amount(normal) : adding  1 Ltrs deionized water when using 80~100g  polishing powder. 

2. Keep the proportion during 1.05-1.1 (measured with Hydrometer)

3. String them well around 10-15 minutes to make them disperse completely.

no special requirement for temperature, in normal would be OK.

4. Ready to use on machine.

This is only reference for mobile phone cover glass.

You need to adjust according to the actual situation

6.Product Feature And Application of optical glass cerium oxide compound 

high accuracy of rare earth polishing powder, is suitable for the covering glass processing technology of touch display screen glass. 

(1)It uses rare earth carbonate as raw material, made red-brown polishing powder, apply to polish cover glass.
(2) The average particle size from 1.4 to 2um, the largest particle is less than 10um can meet the accuracy requirement of cover glass.
(3)It has high polishing speed, good suspension, and easy to clean.
