New Activated Low Zinc Epoxy Primers

Coating standards such as ISO 12944 and SSPC-Paint 20 demand that zinc-rich coatings contain at least 80% and 65% zinc dust by weight in the final dry film, respectively. Traditional zinc-rich primers need this high zinc loading to achieve galvanic protection of steel. However, new technology allows us to develop; for the first time; zinc primers with a lower weight percentage of zinc and still provide similar or better corrosion protection to the steel.
