1. Product Overview

CONAP® CE-1170 is a solvent-based, single-component acrylic conformal coating designed for fast curing and thin-film protection. It is QPL listed for MIL-I-46058C (Type AR), IPC-CC-830B qualified, halogen-free (IEC 61249-2-21), UL 94 V-0 rated, and fluorescent under UV light for inspection. The coating provides excellent adhesion, reparability, flexibility, and reliable hydrolytic stability.


2. Applications

  • Thin-film conformal protection for PCBs and electronic components.

  • Suitable for spray, dip, or brush coating methods.

  • Environments requiring moisture, electrical insulation, and flame resistance.

  • Applications needing easy repairability and solvent removability.
