EZ175C is a two-component polyamide-cured metallic zinc-rich epoxy primer providing long-term protection for steel in severely corrosive environments, with excellent resistance to mechanical wear. Approved by Lloyd's Register (LR) as a pre-construction primer and by Constant Laboratories Inc as a container primer. In accordance with US FDA Regulation Section 175.300, with a suitable topcoat it may be used in fresh water tanks.
As a long-term protective primer for steel in corrosive environments and subject to mechanical wear; as a shop primer for corrosion protection after blast cleaning.

Before application, remove all oil, grease, dust and other contaminants from the surface. * Steel: blast clean to Sa 2.5 or clean with power tools to St 3.
The surface to be coated must be completely clean and dry. Relative humidity must not exceed 85%, and the surface temperature must be at least 2.7 °C (5 °F) above the dew point to avoid condensation.
Base : Curing agent = 4 : 1 (by volume). Mix in proportion before application and stir thoroughly with a power mixer.
At 20 °C/68 °F, 8 h.
Maintain continuous stirring during application to prevent zinc powder settling. Brush application is limited to small areas or touch-up.
Shop primer: DFT 10–20 µm; long-life primer: DFT 35–75 µm.
