Question
What is the 'Dew Point' in coating application?
Expert Answer
The Dew Point is the temperature at which moisture condenses from the air onto a surface. If the substrate temperature is at or below the dew point, a thin film of water forms, which will prevent resin coatings from bonding. We always ensure the substrate is at least 3°C above the dew point before applying any materials to ensure a secure bond.
