Degradation refers to ...

• A. A change in one or more physical properties of a protective material caused by contact with a chemical
• B. A change in the color of the material over time
• C. The weakening of the protective material due to mechanical wear
• D. The chemical reaction that strengthens the material

Answer: (A)

Degradation is the deterioration of a material’s performance caused by environmental or chemical exposure, which leads to changes in its physical properties. The correct description is a change in one or more physical properties of a protective material caused by contact with a chemical. When a chemical interacts with a coating or barrier, it can alter properties such as strength, stiffness, permeability, or integrity, reducing its protective function. Color change can occur, but it isn’t the defining feature of degradation; mechanical wear is driven by abrasion rather than chemical attack; and a chemical reaction that strengthens the material would be the opposite of degradation.
