Permabond 820 quick-setting instant adhesive resists temperature ranges up to 200ºC (390ºF). Typical ethyl cyanoacrylates only resist temperatures to 82ºC (180ºF). Permabond 820 is a modified ethyl cyanoacrylate that has a fast fixture time and high-temperature resistance, making it an ideal choice when bonding components in position on dual-sided PCBs prior to wave soldering. Permabond 820 is colorless, with a viscosity of 100cPs. For additional strength retention during thermal aging, consider Permabond 825.
Cyanoacrylate adhesives are single-component adhesives that cure by reacting to small traces of moisture on the surface of the substrates. Permabond has a complete line of cyanoacrylates that provide adhesion to different substrates, meeting many application needs with various viscosity, color, temperature resistance, gap-filling, cure speed, and compatibility properties available as stock or custom formulation.
