Material Notes:
PERMABOND® 820 is a low viscosity modified ethyl cyanoacrylate suitable for applications where high temperature resistance is required. This material is fast setting and has good adhesion to rubber, metal and plastics.Cyanoacrylate adhesives are single component adhesives that polymerize rapidly when pressed into a thin film between parts. The moisture adsorbed on the surface initiates the curing of the adhesive. Strong bonds are developed extremely fast and on a great variety of materials. These properties make PERMABOND® cyanoacrylates the ideal adhesives for high speed production lines. Features & Benefits: High temperature resistance Rapid curing Ease of use – no mixing or heat cure 100% reactive, no solvents ISO10993 cytotoxicity approval Information provided by Permabond.
