The hazards of floor paint coating leakage

Answer:

1. Defects often occur during the coating, drying, or curing process of floor paint, hiding air or solvents and forming voids or bubbles in the coating film.

2. When the coating dries, air or solvent migration causes pinholes and bubbles; Irregular and uneven surfaces of the coated material can also cause small spots or pores in the coating.

3. Physical damage after painting, such as scratches, are the causes of holiday coating.

Therefore, when there is a leakage coating, corrosive media such as oil, water, acid, gas, etc. invade the interior of the coating or even the substrate through pinholes or cavities, causing the coating to lose its shielding effect, resulting in filamentous corrosion and weakening the surrounding protective layer. If not repaired in a timely manner, these areas will become localized corrosion and the corrosion process will cause the coating to peel off. For coated materials in harsh corrosive environments, such as surfaces continuously immersed in corrosive solvents, it is extremely important to check for leaks, pinholes, and voids to promptly detect and remedy them, ensuring coating quality.
