Water-borne Inorganic Zinc-rich Primer ZD2080 is a zinc-rich primer, a water-borne coating system. As a single coat, it can be used on steel surfaces exposed to moderately to severely corrosive environments and prone to abrasion. It can also be customised with Type II low-lead zinc powder compliant with ASTM D520 per order requirements, with a dry film metallic zinc content ≥80%. Parameters on this page: volume solids 50 ± 3%, dry film thickness 40/60/80 µm.

High chemical resistance in media with pH 6–9; a weldable primer.
Used as a high-performance anti-corrosive primer for steel structures in atmospheric environments;
As a single coat, suitable for steel surfaces exposed to medium to severe corrosive environments and subject to abrasion;
Suitable for the interior of tanks or holds, for oils or solvents of low water content and approved dry cargoes.

First remove grease and other contaminants from the steel surface with a suitable cleaning agent. Remove weld spatter and grind sharp edges so that the specified film thickness can be applied uniformly over the entire surface. All cutting, welding and grinding of the steel plate should be completed before surface preparation as far as possible, then blast clean to Sa 2.5–Sa 3 (ISO 8501-1) with a surface roughness of 50–80 µm (Rz). Too low a surface roughness reduces film adhesion; excessively high roughness should also be avoided to prevent pitting.
Cannot be applied over surfaces with mill scale, poorly prepared surfaces or other paint coatings, as this will cause poor adhesion.
Application should be carried out indoors; the steel surface temperature should be between 5–50 °C, and application is not suitable below 5 °C or above 50 °C. The relative humidity should not exceed 80%, and the substrate surface temperature should be more than 3 °C above the dew point. The application site should be kept ventilated and free of wind and sand; application is not suitable on rainy days, and the coating should not be exposed to condensation, water or rain during curing.
| Mixing | The product is supplied as a unit in two cans. Slowly add the zinc dust pigment to the liquid component and stir continuously until uniform. Then strain through a 60–80 mesh sieve before use. During use, stir the mixed coating continuously to prevent zinc dust settling. Once mixed, it shall be used within the specified pot life. |

Note: the above data are measured under well-ventilated conditions, at typical film thickness and 65% relative humidity, and are for reference only.
Actual drying times and the interval before recoating may be longer or shorter depending on film thickness, ventilation, humidity, the underlying paint, requirements for early handling and mechanical strength, and other factors.
| Subsequent coat | Mist-coat with epoxy sealer or another approved epoxy; for high-temperature areas (≥120 °C), repair or overcoat with an approved heat-resistant coating. Must not be used with alkyd coatings |
|---|
When overcoating with an epoxy intermediate coat, first dilute it and mist-spray a thin coat as a transition coat to seal the pores in the zinc-rich primer and eliminate air bubbles.
This product can only be applied to well blast-cleaned bare steel substrates to white metal.
Before applying the next coat, the water-borne inorganic zinc-rich primer must be fully cured, otherwise adhesion will be affected.
