What is a common problem associated with poor adhesion?

• A. Blistering of the coating
• B. Increase in color vibrancy
• C. Enhanced durability
• D. Improved texture

Answer: (A)

Blistering of the coating is a common problem associated with poor adhesion because it occurs when the bond between the substrate and the coating is compromised. This can lead to the formation of bubbles or blisters on the surface, which can be caused by moisture, contamination, or inadequate surface preparation. When the coating doesn't adhere well, it can trap air and solvents beneath the surface, resulting in these blisters. This is a clear sign that the expected performance and longevity of the coating are at risk due to adhesion issues. The other choices highlight positive attributes that would not arise from poor adhesion; therefore, they do not relate directly to the consequences of inadequate bonding.
