Miller-Stephenson’s Acrylic Conformal Coating

Miller-Stephenson’s Acrylic conformal coating is a tough, abrasion resistant coating providing excellent electrical insulation against high voltage arcing and corona shorts. Dries fast, protects against caustics and corrosives. May be “soldered-through” for ease of repair. Easily removed by solvents. Includes an ultraviolet (UV) indicator. No ODC (ozone depleting chemicals). Miller-Stephenson conformal coating formulations are 100% non-flammable, low odor and low VOC.

Acrylic conformal coatings are most user-friendly of all conformal coating materials due to their ease of application, removal and “repair-through” coating. Acrylics dry and cure rapidly, reaching optimum physical properties in minutes and full cure in less than hour. Additionally, acrylics give off little or no heat during cure, eliminating potential damage to heat-sensitive components, while also expressing minimal shrinkage during cure, exhibiting low glass transition temperatures. One disadvantage is there susceptibility to chemical dissolving upon exposure to isopropyl alcohol or xylene, which are relatively weak solvents. For increased chemical resistance we recommend our Silicone or Urethane Conformal Coating.
