PERMABOND 791 Surface Insensitive Cyanoacrylate

Permabond 791 is a low viscosity, surface insensitive adhesive that will rapidly bond substrates with acidic surfaces such as wood and plated surfaces.  Plastics, metals, ceramics and elastomers are also rapidly bonded. The fast cure minimizes the occurrence of frosting and fogging.
Features and Benefits
  • Extremely fast setting
  • Rapid development of high strength
  • Ease of use – no mixing or heat cure
  • Surface insensitive
  • 100% reactive, no solvents
  • Approved to MIL-A-46050C Type II Class 1 (existing designs) & CID A-A-3097 Type II Class 1 (new designs)

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.

Surface Preparation prior to bonding with Permabond 791
Surfaces should be clean, dry and grease-free before applying the adhesive. Use a suitable solvent (such as acetone or isopropanol) for the degreasing of surfaces. Some metals such as aluminum, copper and its alloys will benefit from light abrasion with emery cloth (or similar), to remove the oxide layer.

Permabond 791 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.
5) Any surplus adhesive can be removed with Permabond CA solvent, nitromethane or acetone.
NB:
For difficult or porous surfaces using a Permabond activator is recommended. If bonding polypropylene, polyethylene, PTFE or silicone, prime first with Permabond Polyolefin Primer (POP).
