Application Instructions
Applicable Substrate and Surface Treatments:
Use a suitable cleaning agent to remove all grease and dirt on the substrate surface, and keep the surface clean, dry and pollution-free.
This product must be applied on the recommended anti-rust coating within the specified recoating interval.
The damaged parts of the primer must be blasted to Sa.2.5 (ISO8501-1) or power-treated to St3 standard, and prime paint should be applied to these parts.
Applicable and Curing
The application surface must be kept clean and dry, and the temperature of the substrate must be 3°C above the dew point to avoid condensation.
This product can also be reacted and cured at a temperature as low as -10°C, as long as there is no frost on the surface.
Outdoor application is prohibited in severe weather such as rain, fog, snow, strong wind and heavy dust.
The temperature is high in summer, be careful with dry spraying, and keep ventilated
during application and drying periods in narrow spaces.
