This silica product for paint and pigment JS-500 has superior performance,its BET can be 540m2/g,the general BET of precipitated silica product is about 170-180m2/g ,so it is about 3 times of general precipitated silica.You can imagine,about 17g of the silica powder ,its total BET is about a big football field.So this silica powder has good absorption,it is used as a carrier for paint nad anti-corrosive pigment.

Q&A:
What is the application of nano silica powder for pigment and coating?
n the UV curable coatings, nano silica is filled into the UV curable coatings, which can significantly improve the hardness and heat resistance of the coatings after curing. At the same time, the curing speed, film hardness, adhesion and thermal stability at low temperature of the UV curing film can be improved.
In architectural coatings, silica can effectively reduce the color difference value caused by ultraviolet and infrared light irradiation, and improve the aging resistance of exterior wall coatings. It can also significantly enhance the hardness, adhesion and weather resistance of the coating, improve the viscosity and anti sinking ability of the coating, and enhance the stability of the coating.
In the ink-jet printing paper coating, if nano silica is added to the pigment, a special coating for digital color ink-jet printing paper with good performance can be made, which can not only make the coating load moderate, but also effectively solve the problem of formaldehyde. The printing effect is good, and the materials are easily available, which can be said to be economical and practical.
