  • Before use, mix thoroughly according to the ratio, adjust viscosity to 16-18 seconds/4 cups at 25°C, spray 2 coats, with a film thickness of 35-50μm.

  • Flash dry for 10-15 minutes at 70-80°C, bake for 45 minutes, or air dry for 24 hours at 25°C.

  • The usable time after mixing the paint is 6 hours at 25°C.

Caustions

  1. It is not advisable to apply too thick a coat at once; each layer requires a certain flash-off time.
  2. To ensure the best spraying results, please use the corresponding hardener and thinner.
  3. Select different types of hardener and thinner based on the varying application temperatures and environmental conditions.
