Zinc rich primers are high performance primers developed for the galvanizing and construction industry. They are used to protect steel surfaces from corrosion through electricity. The zinc and steel combine, producing a small electrical - cathodic cell, which protects the steel at the expense of the zinc. The primer also provides a barrier for continued protection.
APV's Bright Zinc™ Primer is used specifically on galvanized structures that have been repaired during construction. Our version of this primer has a high zinc content, which offers all of the protective qualities of the industry standard, yet retains a bright silver coating that closely mimics the look of galvanized coatings.
APV's Bright Zinc™ Primer is intended for structural steel members - not for thin-gauge metal sheets. The primer must have contact with clean metal, otherwise it will not provide cathodic action necssary for corrosion protection.
Currently, our product is available in both spray or aerosol, and can be formulated in a low VOC solvent blend. It performs best, however, utilizing aerosol applications. The single component system requires no blending of dry zinc prior to the application. As a less bright alternative to the H-8594, a zinc rich grey primer is available without the silver pigmentation.
