Silica Distinguish Hydrophobic And Hydrophilic

Hugestone Enterprise Co.,Ltd | Updated: Jul 29, 2016

In coatings, silica can play anti-settling and thixotropic agents effects.

 

In fact, the hydrophilic silica can also be used in oil-based paint, the hydrophobic silica can also be used in the hydrophilicity.

Silica distinguish hydrophobic and hydrophilic properties mainly due to:

Hydrophobic after paint film formation can stay dry coating surface, high-grade paint is generally hydrophobic, especially in the metal substrate coating, this basically plus hydrophobic silica, the substrate can be maintained without oxidation, so more expensive than hydrophobic to hydrophilic.
