Rusted areas shall be power tool cleaned to St 3.
Surfaces to be coated shall be clean and dry; the substrate temperature shall be at least 3 °C above the dew point to avoid condensation. The product cures at temperatures down to -10 °C provided the surface is free of ice and frost. Provide ample ventilation during application and drying in confined spaces.
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 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 | Hot-dip galvanized, or various epoxy, polyurethane intermediate coats or anti-corrosive primers |
|---|
Use the specified thinner and apply over the compatible primer or intermediate coat; otherwise product quality is affected.
During mixing, avoid contact with water, acids, alkalis, alcohols and the like. Component B reacts readily with water, alcohols and similar substances; the container of the remaining Component B shall be tightly sealed after mixing.
During application and drying/curing, the relative humidity must not exceed 80%.
Condensation or sudden cooling on the surface during or shortly after application causes loss of gloss, blushing and poor quality.
