Zinc rich primers provide the first line of defense in the fight against corrosion. Zinc epoxies compared to zinc silicates as coating solutions, are more flexible regarding curing conditions, they are easier to overcoat and they are less demanding to substrate preparation prior to application.

A new generation of activated zinc rich primers with enhanced corrosion and mechanical properties has been successfully introduced in the market since 2014. This new technology delivers an efficient galvanic protection while providing a more effective barrier and inhibition effects to the coating system.

The purpose of this paper is to present real life and accelerated performance testing that provides additional data that go beyond standard performance in the market. A Life Cycle analysis will be presented as well demonstrating that solutions based on activated zinc have the best sustainability profile, based on outstanding performance and longer durability.
