ZD83-02 ZINDN Silver Zinc-rich Coating
A single-component heavy-duty anticorrosive coating composed of fusing agent, zinc dust, aluminium silver paste, solvent and other ingredients, with a silver-white metallic effect.
Uses dedicated zinc dust together with encapsulated flake aluminium for a good metallic effect; the flake aluminium lies parallel in the film, preventing the ingress of moisture, UV and other agents.
Single-component, simple and convenient to use.
High resistance to discolouration under outdoor rain exposure.
Zinc content of the dry film ≥60%, aluminium content ≥10%.
Suitable for long-term anticorrosive coating of steel structures, usable as a single coat or as a topcoat over cold galvanizing primer; also for maintenance of galvanized components, and an ideal material for replacing or repairing hot-sprayed zinc and hot-dip galvanized layers.

| 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 40–75 µm (medium profile on the ISO 8503-1 comparator). Apply within 4 hours of blasting. |
|---|---|
| Repair of galvanised surfaces | Thoroughly remove grease from the surface with a suitable cleaner, wash off salts and other contaminants with high-pressure fresh water, grind small rusted areas with power tools, and touch up with this product. |
Ambient temperature for application 0–50 °C, air relative humidity not exceeding 95%, and the steel surface temperature shall be at least 3 °C above the dew point; outdoor application is prohibited in 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;
This product is single-component. Stir thoroughly with a power mixer before use, and add the recommended thinner to adjust to a suitable application viscosity.

| Application Methods | Airless spray or air spray is recommended; brush and roller are recommended only for stripe coating, small areas or touch-up, and may cause colour variation. |

| Maximum recoat interval | Unlimited; before applying the next coat, the surface must be clean, dry and free of zinc salts and contaminants. Note: the above data are measured under well-ventilated conditions, at typical film thickness and 75% 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 Sa2.5 or St3, or to ZINDN cold galvanizing surfaces; hot-dip galvanized and hot-sprayed zinc surfaces; |
|---|---|
| Subsequent coat | No subsequent coat is normally required |
The silver zinc-rich coating must be sprayed to full thickness in one pass; avoid touch-up or recoating as far as possible, otherwise inconsistent aluminium flake orientation may cause colour variation in that area.
