What if the paint is not dry in cold weather? How long does it take to bake in the barn? Please kneel down, thank you.

Mainly depends on what paint is sprayed. For example:

1. If it is medium temperature painting, it needs a temperature of about 250 degrees Celsius, while the curing barn is only about 80 degrees Celsius. We can't do it in that century.

2. If you spray two-component PU paint, if the curing barn is 80 degrees Celsius, it is impossible to dry for half an hour or an hour.

The drying of coatings depends on the similarity of film formation: if it is a physical film formation, it can be formed after the solvent evaporates. At this time, the higher the temperature, the faster the solvent volatilization and the faster the film formation. But not as high as possible, and it is also required to control the evaporation rate of the solvent. If it is chemical film formation, certain conditions must be met to make it react chemically before it can be formed.

Because of the cold weather, the construction requirements will be higher. In order to get a good spraying effect, we must first understand the characteristics of the paint, and then formulate corresponding measures.
