Primer coating after shot blasting

By applying shot blasting, the base metal of iron on the surface of the steel is exposed.
The iron is easy to get rust, and the surface of the steels will be all rusted before the customer receives it.
Thus, requiring some measures to prevent the rust.

Zinc coating
Since zinc is contained in the coating material, and the zinc is oxidized instead of the iron, protecting the iron.
* Depending on the type of top coating material, either inorganic zinc rich primer or organic zinc rich primer is used.

Wash type coating
Phosphoric acid is contained in the coating material, and the phosphoric acid reacts to the iron, forming non-rust film.

Customers become easy to manage the standard by changing the tone of the primary rust preventive coating material depending on the standard of the steel material.
