4, use:
1. This product is suitable for the manufacture of chemicals, coatings and heat resistant coatings, solvents, and precision casting silicone adhesive. It is completely hydrolyzed, resulting in oxidation of very fine silicon powder, for the manufacture of phosphors. It can also improve other Resin raw materials and manufacture of silicon polymers.
5, packaging:
200KG plastic drums.
