A high-performance industrial protective primer-finish coating, suitable for steel structure or concrete surfaces in various harsh atmospheric environments, such as large steel structures, bridges, offshore platforms, tank exteriors, ship superstructures, petrochemical equipment and construction machinery equipment, in new construction or maintenance projects, with good adhesion on various old film surfaces and low substrate preparation requirements. A two-component solvent-free primer-finish coating made from inorganic-resin interpenetrating-network-modified weatherable organic polymer resin and highly weatherable pigments; can also be used as a topcoat in a system with a primer. Parameters on this page: volume solids 98 ± 3%, dry film thickness 40/60/100 µm, theoretical spreading rate 0.158 kg/m².

Remove all oil, grease and contaminants from the surface with a suitable cleaner; keep the surface clean, dry and free of contamination.
The substrate must be blast cleaned to Sa 2 (ISO 8501-1) or power-tool cleaned to St2; for maintenance, old film surfaces must be abraded/roughened and loose rust removed.
The surface must be kept clean and dry, and the substrate temperature must be at least 3 °C above the dew point to avoid condensation. Application environment temperature 5–38 °C, relative humidity not more than 85%.
Do not apply outdoors in adverse weather such as rain, fog, snow, strong wind and heavy dust;
Condensation or sudden cooling on the surface during or shortly after application causes loss of gloss, blushing and poor quality.
| 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 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. The coating must be fully cured before immersion service.
| Preceding paint | Cold-spray zinc, epoxy zinc-rich, inorganic zinc-rich, etc. |
|---|
The specified thinner must be used.
During mixing, avoid contact with water, acids, alkalis and alcohols. Component B reacts readily with water and similar substances; seal the Component B container tightly after mixing.
During application and drying/curing, the relative humidity must not exceed 85%.
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.
