What defines a non-convertible coating?

A non-convertible coating is defined by its characteristic of not undergoing a chemical change during the curing process. This means that while the coating is applied and may dry or harden, the molecular structure of the coating itself remains the same, and no new compounds are formed as part of the curing process.

Non-convertible coatings typically rely on physical drying methods, such as solvent evaporation or water loss, rather than a chemical reaction. They often retain their original components and simply lose volume or change their physical state from liquid to solid due to the removal of solvents.

Understanding this characteristic is important for coatings inspectors since it influences not only the performance and durability of the coating but also its application methods and the environmental factors that can impact curing. Knowledge of these properties can inform how one evaluates the suitability of a coating for a specific application or environment.
