Interzinc 52 is a two-part, metallic zinc-rich epoxy primer that provides maximum protection as part of any anti-corrosive coating system. It is designed for aggressive environments in both maintenance and new construction situations, including those found on offshore structures, petrochemical facilities, pulp and paper plants, bridges and power plants. NOTE: In order to ensure good anti-corrosive performance, it is important to achieve a minimum dry film thickness of 1.5 mils (40 microns). To achieve a uniform, coalesced, closed film at this thickness, it will be necessary to thin Interzinc 52 with 10% with International thinners. The film thickness must be compatible with the blast profile achieved during surface preparation. Interzinc 52 is available in blue, gray or green, and provides a matte finish.
