(Coating Formulation) Can Low Zinc Epoxy Primers Work as Well as Traditional Zinc Rich Epoxy Primers

Product Number: 47-COAT_DEC21

Zinc-rich primers, with zinc dust loadings of 80-85% by weight in the dry film, are often the preferred primer during new construction of assets placed in environments with high atmospheric corrosivity. Coating standards such as SSPC-Paint 20 and ISO 12944 demand that zinc-rich primers contain at least 65% and 80% 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. New technology allows us to develop zinc primers with a lower content of zinc and/or different zinc morphology than dust to provide similar or better corrosion protection to the steel.

Zinc rich primer coatings, both organic and inorganic, are extensively used in highly corrosive environments and they are part of a high performance coating system in the Protective Coatings Industry. During the 60’s and the 70’s, zinc rich epoxy primers dominated the market. Later, zinc ethyl silicate primers took over mainly due to their higher potential to corrosion protection. Nowadays however, new developments in zinc epoxy primers are setting the two categories of Zinc rich primers on the same level in terms of anticorrosion performance while adding the advantages of Epoxy based primers.
