Permabond® 820 – High-temperature resistant cyanoacrylate adhesive
Permabond® 820 is a single-component, low-viscosity cyanoacrylate adhesive that has been specially developed for applications requiring high temperature resistance. With a viscosity of 100 mPa·s, it is suitable for precise bonding and reliably fills gaps of up to 0.15 mm.
It offers excellent adhesion to metals, numerous plastics, and rubber. Curing is fast—within 10–15 seconds (depending on the substrate)—and reaches full final strength after 24 hours. In addition, Permabond® 820 is biocompatible (passed cytotoxicity testing) and therefore also suitable for special medical or hygiene-related applications.

Processing instructions
- Surface preparation: Keep surfaces clean, dry, and free of grease (Permabond Cleaner A recommended).
- Application: Apply a small drop to one surface, then join the parts together, ensuring they are precisely aligned.
- Fixing: Apply even pressure and do not move during curing.
-
Optimization:
- For porous or difficult surfaces, use Permabond CSA Activator.
- For polypropylene, polyethylene, PTFE, or silicone, use Permabond Polyolefin Primer (POP).
- Cleaning: Remove excess with Permabond CA Solvent.
storage
- Store in a cool place (34–46 °F).
- Bring to room temperature before use to prevent condensation.
