Silicon Dioxide Powder For Inkjet PET Film Material

Is silica same as silicone?
Firstly, the answer of "is silica same as silicone" is no. These two substrates are totally different.

* Appearance:  we can talk about these two substrates' appearance first. Silica appears as white color podwer. And silicone appears as transparent

or mike white solid

* Structure: then we should mention these two substrates' structures. Silica has spongeous structure, and silicone has mutiple holes structures so it has

strong adhesion property which can adsorb different substrates.

* Production method: For producing silica, we should get Silica Powder from natural silicon dioxide by grinding.Then we should use precipitation method

to change silica powder's self chemical parameter. For producing silicone, firstly adding dilute sulfuric acid into water solution of water glass and stewing.

After a while, there is a solid state hydrosilicic acid gel. Then using water to wash the electrolytic ion Na+ and SO42-( Cl-) and dry the solvent, we can get

silicone.

* Usages: silica powder is often used as additive in coating which can provide excellent matte effect and adhesion property. Silicone is often used as dryer

or catalyst.

Does Silica Matting Agent really work?

Yes, silica Matting Agent is really useful in coating. Normally, it is used as additive to add into coating for enhance coating's self properties include adhesion

property, image clarify property, resistance property and  etc. What's more, the most important usage of silica matting agent in coating is to make the coating

from mirror state to rough state by create a matte effect. This change can reduce the coating's glossy value and reduce the situation of vision obstruction due

to light reflection.

How to make silica coating?

First you should prepare the exact content of silica matting agent before adding into coating's formulation. Then try to add silica matting agent into the coating

and mix it with the other chemical materials by high speed mixture machines. Then put the mixing solvent under the high temperature enviornment to dry. For details,

follow the specific operation instructions.
