Permabond 940
PERMABOND 940 Low Odor Cyanoacrylate Adhesive
Permabond 940 is a low odor, non-fogging, non-frosting alkoxyethyl cyanoacrylate. The reduced odor improves worker comfort. Unsightly fogging adjacent to bondlines, common with other cyanoacrylate adhesives on hot and humid days, is eliminated. The elimination of fogging improves the production rate of acceptable parts as well as their appearance. The adhesive is very stable and will provide optimum performance for one year when refrigerated.
Features and Benefits
- Low odor for improved worker comfort
- Non-frosting –good aesthetic appearance
- Ease of use – no mixing or heat cure
- Bonds most materials
- 100% reactive, no solvents


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. Permabond 940 develops strong bonds 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 940
Permabond 940 Directions for Use
1) Apply the adhesive sparingly to one surface.
2) Then, 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) Remove any surplus adhesive 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).
