Konform AR

Konform® AR is ideal for providing insulation against high-voltage arcing and corona shorts. This extremely effective acrylic conformal coating provides a hard, durable protective barrier against humidity, salt, corrosive vapors and fungus for printed circuit board and electronic assemblies. Konform® AR resin meets MIL-I-46058C, Type AR.

  • Clear transparent coating
  • Excellent dielectric strength
  • Helps prevent arcing and shorts
  • Increases life of electronic assemblies
  • Will not discolor over time under normal use
  • Contains a UV indicator for thorough Quality Control inspection
  • UL Recognized, File E76307

Typical Applications for Konform® AR

  • Aerospace
  • Data Communications
  • Instrumentation
  • Automotive Manufacturing
  • Marine Manufacturing
  • Process Control



Konform® AR is generally compatible with most materials found on printed circuit boards. As with any chemical product, product/component compatibility must be determined on a non-critical area prior to use.

Usage Instructions

For industrial use only. Read MSDS carefully prior to use. Before applying Konform® AR conformal coatings, clean circuit boards to remove contamination and allow to dry. Cleaning may be performed with Chemtronics® Electro-Wash® NX or Electro-Wash® PX.

Spray Application

Apply top to bottom, allowing coating to flow evenly around components. Rotate PCB 90° and repeat application. Rotate and apply coating two additional times, then allow board to cure. If additional thickness is desired, apply additional coatings. When using liquid spray with automatic dispensing equipment, adjustments may be required in application rate and viscosity.

Dip Application

Using automatic equipment or hand immersion technique, slowly immerse PCB into the coating and remove slowly. Use an average rate of approximately 1 foot per minute. After allowing the board to cure, process may be repeated to achieve desired thickness.

Brush Applications

Evenly apply coating to areas desired at thickness required. Allow time for curing before reapplying to achieve a thick coating. Use Chemask® to protect components during conformal coating process.


After application, cured Konform® AR may be removed by soaking in Chemtronics® Electro-Wash® Two Step or an aromatic solvent (such as xylene), or a short chain ketone (such as acetone).
