Causes of blistering in glass bottles after high-temperature spray painting

2023-06-08 242

The main reasons for foaming are:

1. The coating comes into contact with water or is exposed to high temperatures;

2. The solvent volatilizes too quickly, resulting in a higher viscosity of the coating;

3. Paint before the gas mixed into the paint is fully released;

4. Some solid substances in the coating will automatically decompose and release gases, which cannot penetrate the coating film and cause bubbles.



1. The coating should not come into contact with water during construction, and the dry coating film should avoid long-term exposure to high humidity environments;

2. Use matching solvents and diluents, and adjust the viscosity of the coating appropriately;

3. Add alcohol solvents and defoamer additives.

4. The mixed coating should be cured for some time before application.
