Description
The Conathane CE-1155 coating is a two-component polyurethane conformal coating used when printed circuit boards need a moisture barrier, electrical insulation, and flexible film build without giving up process flexibility. ELANTAS lists CE-1155 for spray, dip, and brush application, making the quart kit a practical size for maintenance runs, qualification work, and lower-volume electronics production.
Key Features and Benefits
- QPL listed for MIL-I-46058C Type UR work where a qualified conformal coating matters.
- UL94 V-0 performance supports assemblies that need a flame-rated coating film.
- Fluorescence under UV light helps inspectors confirm coverage after application.
- Flexible cured film resists cracking on phenolic and epoxy-glass laminates.
- Excellent hydrolytic stability supports electronics exposed to humidity and washdown risk.
- Fast cure options let teams balance room-temperature processing and heated throughput.
Common Applications for Conathane CE-1155 Coating
- Protecting printed circuit boards in industrial control assemblies
- Coating electronics that face moisture, condensation, or splash exposure
- Sealing thin-film assemblies that need an electrical and environmental barrier
- Supporting aerospace, defense, and electronics builds that call for qualified urethane coating systems
- Bench, dip, or spray processes where UV inspection is part of the work instruction
Compatible Electronics Assemblies
- Phenolic laminates
- Epoxy-glass laminates
- Thin-film electronic assemblies
- Printed circuit boards that require brush, spray, or dip coating methods
