What is a common consequence of entrapment of solvents in a coating system?

The entrapment of solvents in a coating system can lead to blistering, which occurs when trapped solvents vaporize and create pressure beneath the coating film. As the pressure increases, it may cause the coating to bulge and eventually form blisters. This phenomenon compromises the integrity of the coating, leading to potential failures such as flaking or delamination if not addressed.

In contrast, other consequences such as chalking, peeling, and fading may be related to different mechanisms. Chalking typically arises from degradation of the pigment due to UV exposure, while peeling often results from improper surface preparation or adhesion failures. Fading generally relates to the breakdown of pigments in the presence of environmental factors, rather than solvent entrapment. Understanding these specific causes is crucial for maintaining the quality and longevity of a painted surface.
