EZ175 is a two-component polyamide-cured metallic zinc-rich epoxy primer that provides long-term protection for steel in severely corrosive environments and offers 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, it may be used in fresh water tanks when applied with a suitable topcoat.
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.
| Appearance and colour | Flat, metallic grey (1184) |
|---|---|
| Volume Solids | Approx. 50% (measured per ISO 3233) |
| VOC | 430 g/L (GB/T 23985-2009 theoretical value) |
| Theoretical Spreading Rate | On smooth surfaces: 12.0 m²/L at 40 µm dry film thickness |
| density | After mixing, approx. 2.40 |
| Flash Point | Base EZ175 PTA: 15°C/59°F (closed cup); hardener EZ175 PTB: 26°C/79°F (closed cup) |
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 : hardener = 4:1 (by volume), 12.5:1 (by weight). Mix in the specified ratio before application and stir thoroughly with a power mixer.
At 20 °C/68 °F, 8 h.
Thinner No.053. For airless spray, select by season: No.053 spring/autumn, No.053S summer, No.053W winter, No.053BS shop zinc-rich primer.
Apply by brush, roller or spray (air or airless). Airless spray: nozzle orifice 432 µm (0.017″); nozzle pressure 17.2 MPa; fan angle 30°–90°. Maintain continuous agitation during application to prevent settling of the zinc pigment. Brush application is limited to small areas or touch-up.
Shop primer: DFT 10–20 µm; long-life primer: DFT 35–75 µm. Dry film thickness varies with use and location.
