NASA ASTM E595 Approved
Low Outgassing Conformal Coating

Added to the DOD QPL & MIL-I-46058C Certified

Designed for satellite, spacecraft, and critical PCB assembly applications, dual-cure 9771 is a reworkable coating that cures rapidly with light first and then with moisture to ensure material that flows underneath components on PCBs fully cures.
Assigned number 09841 in the NASA MAPTIS materials database, 9771 was verfied by a NASA-approved 3rd party lab that it meets low outgassing ASTM E595 and has low ionic content for cleaner PCBs during extreme conditions.
Watch this short video to see where 9771 coating and other light-curable materials are used in spacecraft and satellite applications.
Light-Curable Materials for Satellite and Spacecraft
The MIL-I-46058C standard establishes conformal coating compliance requirements and evaluates them to an extensive list of properties, including curing time and temperature, material thickness, moisture resistance, fungus resistance, insulation resistance, flexibility, hydrolytic stability, and flame resistance.
The on-demand light-cure capability of 9771 means that PCBs don’t have to flash off, then go through heat cure, so boards are immediately available for the next process step. Other key features include:
  • Added to the Defense Logistics Agency Qualified Products List (QPL)
  • Certified to meet Mil-Std 883 Method 5011
  • UL 94 V0 flammability rated and UL 746E recognized
  • Resistance to corrosion, temperature, and humidity
  • Coating thickness to 0.008” (0.20mm)
  • Bright blue fluorescing for fast, high-speed, in-line quality inspection
  • Eco-friendly, one-component material requires no mixing
  • Conforms to RoHS standards
