Product characteristics

 

Alkaline silica sol is a colloidal solution of amorphous silica particles of different sizes in water. Its pH value ranges from 9 to 11. It is called alkaline silica sol. Its molecular formula is mSiO 2.nH 2.O The particle size can be controlled at 7-15 nanometers.

1. It has large specific surface area and good adsorbability.

2. It has good adhesion, high temperature resistance, good hydrophilicity and oil repellency.

 

Product Application Area

 

JN-830 and JN-1430 can be used in precision casting, ceramics, coatings and other industries.

JN-1430-C1, JN-1430-A2, JN-1430-C3, JN-40, JN-40-C1 can be transported in refractories, petroleum catalysts and other industries.
