What does Dew Point refer to in coatings inspection?

Dew Point refers to the temperature at which moisture in the air begins to condense into water droplets. This phenomenon is crucial in coatings inspection because if the surface temperature of the material being coated is lower than the dew point, moisture can accumulate on the surface. This moisture can lead to various issues, such as poor adhesion, bubbling, and corrosion under the coating once applied. Therefore, understanding and measuring dew point is essential for ensuring that the conditions are right for successful coating application.

By recognizing the significance of the dew point, coatings inspectors can make informed decisions about when to apply coatings and ensure that the conditions are conducive to achieving a durable and effective outcome.
