2019-07-22
The main reasons for the high temperature spray coating of glass Cosmetic bottles as bellow:

1. The coating film is in contact with water or exposed to high temperature;
2. The solvent evaporates too quickly and the viscosity of the coating is high;
3. The gas mixed in the paint is not released after being released;
4. Some solid substances in the coating will be automatically liberated from the gas, but will not blister through the coating film.

The solutions for glass bottle high temperature spray paint :

1. The paint should not be in contact with water during construction. The dry coating should avoid exposure to high humidity for a long time;
2, using the matching solvent and thinner, the viscosity of the coating should be adjusted moderately;
3. It is best to add an alcohol solvent and a defoaming aid.
4. After the stirring, the paint should be matured after a certain period of time.
