Instructions：
1. Mix thoroughly according to the proportion before use, adjust the mixture’s viscosity to 16-18 seconds/4 cups, spray 2 times at 25°C, with the film thickness reaching 25-45μm.
2. Flash dry for 10-15min
Bake at 70-80°C for 60min
Air dry at 25°C for 24h
3. After being mixed, the paint should be stored at 25°C and used within 6 hours.
Things to note：
1. The primer should not be excessively thick, or it might slow down the drying process or reduce the adhesion between the coating layers.
2. Use the complementary curing agent and thinner to achieve the desire results.
3. Do not apply if the temperature is 5°C.
