It is available in both room-temperature and heat-cure versions and is used in aerospace, automotive, and industrial manufacturing applications where permanent, load-bearing bonds are required. What substrates does Permabond ET5422 bond?ET5422 bonds steel, aluminum, composites, ceramics, glass, and concrete. It performs particularly well on metal-to-metal and metal-to-composite joints. Always test on your specific substrate combination to confirm adhesion and compatibility with your surface finish or treatment. What is the mix ratio for ET5422?ET5422 uses a 1:1 mix ratio by volume, making it compatible with standard dual-cartridge dispensing guns (manual or pneumatic). No measuring or hand-mixing is required — the static mixing nozzle handles all mixing automatically. Does Permabond ET5422 cure at room temperature?Yes — ET5422 is available in a room-temperature cure version that requires no additional equipment. A heat-cure version is also available for applications requiring enhanced elevated temperature resistance. Consult the ET5422 Technical Data Sheet for specific cure schedules, open times, and fixture times at various temperatures. What is the difference between the 50ml and 400ml ET5422 kits?The 50ml kit (ET05422K050C0101, case of 25) is designed for bench repair, prototyping, and low-volume assembly where smaller quantities are needed per application. The 400ml kit (ET05422K400C0101, case of 6) is optimized for production dispensing with pneumatic guns in higher-volume manufacturing environments. Is Permabond ET5422 suitable for aerospace applications?Yes — the heat-cure version of ET5422 is appropriate for aerospace, automotive, and high-performance industrial applications requiring elevated temperature resistance and structural bond strength. Verify compliance with your specific aerospace specification requirements before use.
