PERMABOND® 825 is a low viscosity cyanoacrylate adhesive that provides higher strength at high temperature. This fast-setting cyanoacrylate bonds metals, rubbers, plastics, and more. Permabond 825 resists up to 392°F (200°C) and has excellent retention of strength during thermal aging. PATENTED TECHNOLOGY
Typical ethyl cyanoacrylates resist up to 180°F (82°C) with special grades resisting as high as 250°F (120°C). Generally, methyl cyanoacrylates resist 195°F (90°C). Specialty allyl cyanoacrylates can resist up to 482°F (250°C). However, these require a post-cure or secondary heat cure to achieve the temperature resistance.
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.
Directions for use:
1) Apply the adhesive sparingly to one surface.
2) Bring the components together quickly and correctly aligned.
3) Apply sufficient pressure to ensure the adhesive spreads into a thin film.
4) Do not disturb or re–align until sufficient strength is achieved, normally in a few seconds.
