This coating can be applied in the painting of aluminum type materials which can be sprayed continuously during processing. It can be divided into two types: primer and topcoat. Please refer to the relevant operation instructions. Spray primer (thickness around 15-20 µ m)=>stillness for 3-5 minutes or baking at 60-80 ℃ × 3-5 minutes before spraying the topcoat (with thickness around 15-20 µ m)==>stillness for 5-10 minutes==>Baking at 180 ℃ ×15-20 minutes, and cool down to offline


Precautions

1.Before using the paint solution must be thoroughly stirred and diluted with water-based solvents or deionized water to the operation viscosity, with a dilution rate around 30-40%,and filter with a 200-300 mesh filter before operation.

2.The relative humidity of the operation environment shall not exceed 80% and good ventilation shall be maintained.

3.During operation, the surface of the coated material should be kept clean, dry, flat, and free of pollutants such as dust and oil.

4.Coatings should be stored in a cool and dry place, with a storage temperature higher than 5 ℃.

5.The storage period of the paint is six months, please be sure to exhaust it within six months.
