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.

Solution:

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.
