Surface Preparation
The substrate surface shall be clean, free of oil, dust and other contaminants, flat and dry. Primer pretreatment is required in advance.
Environmental conditions
1.Coating ambient temperature: 0–50°C; relative humidity below 65%.
2.Substrate surface temperature shall be at least 10°C above dew point.
3.Temperature and humidity shall be measured close to the substrate.
4.Do not apply coating under harsh weather such as rain, snow, strong wind or sandstorm.
Packaging Specification
10 kg per drum
Storage
This product should be stored in a cool, dry, ventilated indoor warehouse, storage period of half a year.
Safety
All fire sources are strictly prohibited in the batching and construction sites, and good ventilation is maintained. Lacquer splash on the skin should be washed immediately with soapy water, splash into the eyes, should be immediately washed with plenty of water, and then find a doctor to check.
