WZ3300 is a two-component water-borne epoxy resin-based zinc-rich primer with good corrosion resistance, capable of long-term protection of steel plates in severe corrosive environments, and with good tear resistance and abrasion resistance. WZ3300 is a low-VOC water-soluble product, suitable for dry cargo containers and heavy-duty steel structures.
As a permanent primer, for protection of steel in corrosive environments and under high-intensity mechanical wear; as a shop primer, for corrosion protection of steel after abrasive blasting.
| Appearance and colour | Flat, metallic grey |
|---|---|
| Volume Solids | Approx. 50% |
| Theoretical Spreading Rate | 12.25 m²/L (smooth surface, dry film thickness 40 µm) |
| density | Approx. 2.3 kg/L after mixing of base and hardener |
| Flash Point | Base (WZ3300PTA): 13 °C/55.4 °F (closed cup); hardener (WZ3300PTB): non-flammable |
| Drying Time | Touch dry: 10 °C 10 min, 20 °C 5 min, 30 °C 2 min; hard dry: 20 min / 10 min / 5 min (data for guidance only) |
All grease, dust and other contaminants must be removed from the surface to be coated with solvent or clean water before application. * New steel: abrasive blast clean to minimum Sa2.5 "near-white".
Temperature normally 10 °C–40 °C, preferably 15 °C–30 °C; relative humidity normally 20–80%, preferably 40–60%. Surface temperature must be at least 2.7 °C (5 °F) above dew point to avoid condensation.
Base (WZ3300PTA): hardener (WZ3300PTB) = 100:26.75 (by weight). Stir at medium speed with a mixer for 5 min before application.
At 20 °C / 68 °F, the pot life after mixing is 3 hours.
Pure potable water, dilution up to 30% by volume (up to 100% for shop primer).
Apply by brush or spray (air or airless). Airless spray: tip size 0.013"~0.017" (shop primer 0.017"~0.021"); nozzle pressure 2,100~2,400 psi; fan 30°~90° (shop primer 80°~90°). Brush application is for small areas only.
Shop primer dry film 10–20 µm; permanent primer dry film 30–75 µm.
