Which property is NOT associated with polyester coatings?

Polyester coatings are known for several key properties that make them popular in various applications. When identifying a property that is not typically associated with polyester coatings, moisture susceptibility stands out as the correct answer.

Polyester coatings are generally formulated to be resistant to moisture and environmental factors, which helps them maintain their integrity and performance over time. They are commonly used in areas where exposure to moisture is a concern, such as in marine applications or exterior coatings. This resistance to moisture contributes to their durability and longevity.

In contrast, excellent abrasion resistance, low flexibility, and short pot life are characteristics that can be associated with polyester coatings. The coatings can provide solid protection against wear and tear, they may exhibit less flexibility compared to other resin types, and certain formulations can indeed have a relatively short pot life, which refers to the amount of time the mixed material remains workable before it begins to cure or harden.

Thus, "moisture susceptibility" accurately reflects a property that is not commonly linked with polyester coatings, reinforcing their reputation for durability and reliability in various environmental conditions.
