White Silicon Dioxide Powder For Electrophoretic Coatings

Why choose silicon dioxide as additive agent in e-coating?

First of all, silicon dioxide is common chemical material in the nature. So its cost is acceptable for the rubber,plastic, paint 

manufacturers. Second,it also has a very stable chemical property which is non-toxic, non-corrosive, odorless. Third, it is 

not so complex to change the silicon dioxide's self properties to use in various industries. We often use precipitation method 

to change its particle size, sulfate content, electrical conductivity and so on.

Making electrophoretic coating should needs four substances. Film-forming substance, pigment, additive and solvent. Adding 

silicon dioxide as additive agent in electrophoretic coating can make functions as below.

1. Silicon dioxide can enhance coating's hardeness and scratches resistance which can improve the its durability and using 

time.

2. Silicon dioxide can enhance coating's glossy and whiteness.

3. Silicon dioxide can enhance coating's filling and covering properties.This can decrease the coating's transparency which 

make the coating covered.

4. Increase the UV resistance of the coating and extend the service life of the coating.

5. Adjust the rheological properties of the coating to make painting easier.

In short, adding white silica powder can improve the performance of the coating and enhance the effect of painting.
