In industrial finishing, air dry coatings are paints or protective varnishes designed to cure (harden) at ambient room temperatures.
The Mechanism: Unlike baked enamels or powder coatings that require massive, energy-intensive curing ovens, air dry coatings solidify through the natural evaporation of chemical solvents or through oxidation when exposed to the air.
Industrial Use: They are highly practical for massive structural steel pipes or field touch-ups at construction sites where passing the material through an oven is physically impossible.
