ZD6080 Epoxy Zinc-rich Primer is a zinc-rich primer in an epoxy coating system. During maintenance, its cathodic protective anti-corrosion effect can be achieved only when it is applied to surfaces prepared to bare steel. It is a two-component high-solids heavy-duty epoxy zinc-rich primer composed of epoxy resin, zinc powder, solvent, and additives with a polyamide hardener; the metallic zinc content in the dry film is ≥80%. Parameters on this page: volume solids 65 ± 3%, dry film thickness 40/60/80 µm, theoretical spreading rate 0.307 kg/m².

ZD6080 Epoxy Zinc-rich Primer
A two-component high-solids heavy-duty epoxy zinc-rich primer composed of epoxy resin, zinc powder, solvent, and additives with a polyamide hardener, with a dry film metallic zinc content of ≥80%.
The film has excellent anti-corrosion properties;
Provides cathodic protection to locally damaged areas;
Excellent adhesion to blast-cleaned carbon steel surfaces.
As a primer for blast-cleaned bare steel in medium to severe corrosive environments, such as steel structures, bridges, port machinery, offshore platforms, construction machinery, storage tanks, pipelines and power facilities. Used with high-performance paints, it further improves the anti-corrosion performance of the coating system;
Suitable for approved zinc-rich shop primer surfaces to be retained;
Suitable for repair of damaged areas of galvanised parts or zinc silicate primer coatings;
For maintenance, its cathodic protection anti-corrosion effect is achieved only on surfaces prepared to bare steel.

| New steel | Remove grease from the surface with a suitable cleaner, and rinse off salts and other contaminants with fresh water. Remove weld slag, and grind welds and sharp edges smooth. Abrasive blast clean to Sa 2.5 (ISO 8501-1); the ideal surface roughness is Rz 30–75 µm (medium roughness on the ISO 8503-1 comparator). Apply the primer within 4 hours of blast cleaning. |
|---|---|
| Shop-primed surface | Welds, heat-treated areas and damaged areas must be blast cleaned to Sa 2.5 (ISO 8501-1) or cleaned with power tools to St 3. Only sound, approved zinc-rich shop primer may be retained. When exposed to humid conditions, zinc salts form on the zinc-rich primer surface; before recoating, remove soluble zinc salts with fresh water and remove white rust (zinc corrosion products) with a stiff brush. If the zinc-rich primer is damaged over a large area, full blast cleaning is recommended. |
| Repair | Thoroughly remove grease from the surface with a suitable cleaner, and wash off salts and other contaminants with high-pressure fresh water. Remove rust and other loose material by blast cleaning; alternatively, grind small rusted areas with power tools and touch up bare areas with this product. |
Application environment temperature 5–38 °C, relative humidity not more than 85%, and the steel surface temperature should be at least 3 °C above the dew point. Do not apply outdoors in adverse weather such as rain, fog, snow, strong wind and heavy dust;
In hot summer weather, guard against dry spray; provide ample ventilation during application and drying in confined spaces;
At application environment temperatures of -5 to 5 °C, use a low-temperature-curing product or take other measures to ensure proper film curing.
| Mixing | This product is supplied as two containers forming one unit. Stir the base thoroughly with a power mixer, add the curing agent in the specified ratio, stir again with a power mixer, and add the recommended thinner to adjust to a suitable application viscosity. Once mixed, use within the specified pot life. |

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.
| Preceding coat | Apply directly to steel surfaces prepared to Sa 2.5 or St 3, or to approved shop primer surfaces. |
