ZD5100 Waterborne Primer-Topcoat is a waterborne coating. Used as a primer-topcoat or as a primer on abrasive blast cleaned bare steel in light to medium corrosive environments, such as building steel structures, bridges, construction machinery, storage tanks and pipelines, and power facilities; used with high-performance coatings, it further improves the corrosion protection of the coating system. An environmentally friendly waterborne one-component anticorrosive primer-topcoat composed of waterborne acrylic-modified epoxy ester emulsion, anti-corrosive pigments, water and additives. Page parameters: volume solids 50 ± 3%, dry film thickness 40/60/80 µm, theoretical spreading rate 0.192 kg/m².

ZD5100 Waterborne Primer-Topcoat
An environmentally friendly waterborne one-component anticorrosive primer-topcoat composed of waterborne acrylic-modified epoxy ester emulsion, anti-corrosive pigments, water and additives.
The film has high anticorrosive performance;
The film has good gloss and colour retention;
Fast drying and simple application.
As a primer-topcoat or as a primer, for abrasive blast cleaned bare steel in light to moderate corrosive environments, such as building steel structures, bridges, construction machinery, storage tanks and pipelines, and power facilities; when used with high-performance coatings, it further improves the corrosion protection performance of the coating system;

| Practical Spreading Rate | Allowing for a suitable loss factor |
|---|
| New steel | Remove grease with a suitable cleaner and rinse salts and other contamination off the surface with fresh water. Remove weld slag, grind welds and sharp edges smooth, and blast clean to Sa2.5 (ISO 8501-1), ideally achieving a surface profile of Rz 30–75 µm (medium profile on the ISO 8503-1 comparator). Apply the primer within 4 hours of blasting. Steel may also be abraded 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 ambient temperature 5–40°C, relative air humidity not more than 80%, and steel surface temperature at least 3°C above the dew point; outdoor use is prohibited in adverse weather such as rain, fog, snow, strong wind and heavy dust;
| Mixing | The product is supplied in a single can. Before use, stir evenly with an electric mixer and add an appropriate amount of deionized water to adjust to a suitable application viscosity. |
|---|---|
| Thinner / Cleaning Solvent | Deionised water (clean tools before the paint is touch dry; once touch dry, a glycol ether solvent may be used for tool cleaning) |
| Application Methods | Airless spray or air spray is recommended; brush and roller are recommended only for touch-up, small-area application or repair. |
|---|
Use a soft brush or short-nap roller to minimise air entrapment.

| Hard Dry | 36 h | 30 h | 24 h | 18 h |
| Minimum recoat interval | 30 h | 24 h | 20 h | 14 h |
| Maximum recoat interval | 6 months; the surface shall be clean and free from contamination |
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. The coating must be fully cured before immersion service.
| Preceding paint | Various water-borne or solvent-borne acrylic, epoxy, polyurethane intermediate coats or anti-corrosive primers |
|---|
During application and drying/curing, the relative humidity must not exceed 80%.
With roller and brush application, several coats may be required to achieve full hiding, especially for certain lead-free bright colours such as yellow and orange.
