ZDW6500 Water-borne Epoxy Primer is a water-borne coating used as a primer. As a primer, it is used on blast-cleaned bare steel surfaces in light to medium corrosive environments, such as building steel structures, bridges, construction machinery, storage tanks and pipelines, power facilities, etc., and is used in combination with high-performance coatings to further improve the anti-corrosion performance of the coating. An environmentally friendly water-borne two-component anti-corrosion primer composed of water-borne epoxy resin, anti-rust pigments, solvents and additives with a polyamide curing agent. Parameters on this page: volume solids 50 ± 3%, dry film thickness 40/60/80 µm, theoretical spreading rate 0.216 kg/m².

ZDW6500 Water-borne Epoxy Primer
An environmentally friendly water-borne two-component anti-corrosion primer composed of water-borne epoxy resin, anti-rust pigments, solvents and additives with a polyamide curing agent.
The film has high anticorrosive performance;
Excellent adhesion to blast-cleaned carbon steel surfaces.
As a primer, used on blast-cleaned bare steel surfaces in light to medium corrosive environments, such as building steel structures, bridges, construction machinery, storage tanks and pipelines, power facilities, etc., and used in combination with high-performance coatings to further improve the anti-corrosion performance of the coating;

| Practical Spreading Rate | Allowing for a suitable loss factor |
|---|---|
| VOC content | ≤150g/L |
Grind welds and sharp edges flat; blast cleaning to Sa2.5 (ISO 8501-1) and a surface roughness of Rz30 µm–75 µm (medium roughness in the ISO 8503-1 comparator) are ideal; the primer should preferably be applied within 4 h after blast cleaning. Steel may also be power-tool cleaned to St3.
| Repair | Remove grease thoroughly with a suitable cleaner, and wash off salts and other contamination with high-pressure fresh water. Blast cleaning is preferred to remove rust and other loose material; power tools may also be used to abrade small rusted areas, which shall then be touched up with this product. |
|---|
Application environment temperature 10–40 °C, relative humidity not more than 80%, 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;
| 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. |

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.
| Preceding coat | Apply directly to steel surfaces prepared to Sa 2.5 or to approved shop primer surfaces. |
|---|---|
| Subsequent coat | Epoxy and chlorinated rubber coatings must not be used with alkyd coatings |
