ET503
Permabond ET503 is a two-part, fast-setting epoxy that bonds wood, metals, ceramics and selected plastics such as ABS and polycarbonate. It cures rapidly at room temperature and reaches working strength within 20 minutes. The tough, high-strength adhesive is easy to apply and resists water and humidity.
For UAV maintenance, ET503 is ideal for structural repair of compatible composite airframe panels, housings and bonded joints. Its fast setting time supports efficient repair work, and its environmental resistance is suited to components that may be exposed to moisture during service.
