Zinc Primer

The application of a zinc primer which is specially formulated to protect steel from corrosion and can significantly increase the life of any of our products.

Unlike a normal paint primer which simply forms a physical barrier to prevent oxidisation of the steel, this primer contains a high concentration of zinc dust which forms Zinc salts when it comes into contact with the steel. The tiny zinc salt particles effectively fill the pores in the primer and form a cathodic cell in which the zinc oxidises instead of the steel, thus the zinc is sacrificed to protect the steel.

Although an additional cost, this anti-corrosive primer is highly recommended and a worthwhile investment as an additional process prior to powder coating.
