After spraying, the paint should be leveled for 15-20 minutes before entering the drying room for drying.
The surface of the initially sprayed paint is undulating, and it is rich in volatile phenol with a strong flow. After a short period of time, the paint surface becomes smooth through micro-flow, which means “leveling”. The volatile phenol in the whole layer can be evenly distributed, and this process should keep long because it is the key to leveling. If it goes straight into the drying room under high temperature without leveling, the surface paint will be dried quickly.
When the leveled paint is to be dried, the drying mode should be adjusted from low-high mode to high-low mode. After leveling, although most of the volatile phenols in the whole layer of the paint can be volatilized, if it suddenly enters a high temperature environment, the paint surface will still be rapidly dried, which will block the volatilization of the internal volatile phenols, thus the paint film and the drying efficiency will be negatively influenced. If the paint is directly enters the low temperature environment, the heat will be wasted, and the rapid temperature change will cause strain on the paint film structure.
