What is the appropriate temperature for painting cars in winter?

Polyester paint: 18℃-25℃, relative humidity below 75%;

Nitrocellulose paint: 18℃-25℃, and the relative humidity is lower than 75% (Nitrocellulose paint cannot be applied when the relative humidity is higher than 95%, and when the humidity is lower than 0℃ and higher than 75%, it will cause slow drying, slow reaction, loss of light, whitening and other phenomena).

Latex paint: above 5℃, the relative humidity is less than 85% (theoretically, the minimum film-forming humidity of latex paint can be adjusted to 0℃, but in practice, the film is thin, which is easy to freeze and destroy latex particles in cold environment, and the film-forming environment is low, which easily leads to incomplete film formation. Help to avoid cold and rain.

In spray painting, there are various solvents containing benzene and benzene compounds, such as toluene and xylene. Industrial solvents such as ethanol and butanol commonly used in diluents are also toxic, and some are even highly toxic, such as methanol. The existence of these toxic substances is harmful to human nervous system, respiratory system and skin. The most common phenomena are benzene poisoning and lacquer poisoning.

In the process of painting, a large number of volatile gases are often produced and spread in the air. These toxic hot gases, if inhaled by human body, will cause nervous system diseases, such as dizziness, palpitation, nausea and vomiting.

If fingers and other parts are often exposed to various solvents and toxic gases, it will also cause skin corrosion, degreasing, itching, roughness, cracking and other diseases.
