Foaming Causes and Countermeasures of Glass Bottles after High Temperature Spray Painting

The main reasons for the blistering of glass bottles at high temperature are:

1. The film is exposed to water or exposed to high temperatures;

2, solvent evaporation too fast, the viscosity of the coating is high;

3, stirring mixed into the paint gas is not released on the coating;

4. Some solid substances in the coating will automatically release the gas, but the film will not foam.

Glass bottle high temperature paint solution method:

1. The paint should not be in contact with water during construction. The dry film should not be exposed under high humidity conditions for a long time.

2, the use of supporting solvents and thinners, coating viscosity to moderate adjustment;

3, it is best to add alcohol solvents and defoaming aids.

4, after the stirring coating should be matured after a certain period of time after the construction
