Drying time is the duration required for a solvent-based acrylic conformal coating to dry out as the solvents evaporate. Unlike other types of conformal coatings that undergo both drying and curing processes, the acrylic resin in this specific coating does not polymerize or cure. Instead, it simply dries out over time. This unique characteristic allows the coating to be re-dissolved back into the evaporated solvents and reform the coating.
