‘White rust’; the enemy of zinc coated steel strips is a form of corrosion that can occur during certain storage conditions and is unacceptable for critical applications in white goods, construction and other industries.

Passivation treatments form a barrier to corrosion and are applied in-line. PrimeCoat® from AD CCT is a market leader in chrome free, products in Europe.

AD CCT PrimeCoat® passivation products are both economic and effective in use. The passivated coiled strip can be stored without oil and the passivated surface still offers benefits in ease of formability, deep drawing, post paint ability, as well as extended corrosion protection.

AD International has experience and expertise in the treatment of substrates, such as magnesium; aluminum alloyed zinc coated steel and galvannealed strip products.
