HN-5508AB is a two-component epoxy potting compound with a 5:1 mix ratio, specially formulated for aerospace electronic module encapsulation, avionics circuit protection and high-voltage component insulation. Based on thermosetting epoxy resin, it reacts with the curing agent to form a robust and durable insulator with excellent insulation properties, chemical resistance, high mechanical strength and strong adhesion. With dielectric strength up to 22 kV/mm, it provides reliable insulation, moisture protection, dustproofing, waterproofing and physical fixing for electronic components operating in demanding aerospace and harsh-environment applications.
