CHEMTRONICS TDS # CTAR Technical Data Sheet Konform AR PRODUCT DESCRIPTION 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 Konform AR is ideal for applications in: Aerospace Data Communications Instrumentation Automotive Manufacturing Marine Manufacturing Process Control TYPICAL PRODUCT DATA AND PHYSICAL PROPERTIES Usable Temp.

As with any chemical product, product/component compatibility must be determined on a non-critical area prior to use. Performance Moisture Resistance Good Removability Excellent Ease of Repair Excellent Flexibility Fair Adhesion Excellent Abrasion Resistance Excellent Solvent Resistance Fair 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 Flux-Off products. 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. REMOVAL: After application, cured Konform AR may be removed by soaking in Chemtronics Electro-Wash Two Step. AVAILABILITY CTAR-12 11.5 oz.
