Acrylic – Mil-Spec Type AR Coating
Acrylic conformal coatings are generally a fast drying, single component, conformal coating that provides excellent moisture and environmental protection for printed circuit assemblies. The cured film demonstrates exceptional flexibility and fluoresces under UV light for ease of inspection and is easily repaired.
Acrylics are fairly inexpensive. The substrate must be very clean for the successful application of any conformal coating. Surfaces must be free of moisture, dirt, wax, grease, flux residues and all other contaminants. Contamination under the coating could cause problems that may lead to assembly failures.
Acrylic Conformal Coatings can be Dipped, Sprayed or Brushed. They viscosity can be adjusted with thinning agents using the manufacturers specifications.
