Acrylic conformal coatings are perhaps the most popular of all conformal coating materials due to their ease of application, removal and forgiving nature. Acrylics dry rapidly, reaching optimum physical properties in minutes, are fungus resistant and provide long pot life. Additionally, acrylics give off little or no heat during cure, eliminating potential damage to heat-sensitive components. They do not shrink during cure and have good humidity resistance and exhibit low glass transition temperatures.

Acrylic resin coatings are easy to apply and can be easily removed for rework using solvents. Spot removal of the coating to repair a solder joint or replace a component can be easily accomplished by localised solvent application. Although not encouraged, Acrylic coatings can be soldered through if preferred.
