Material Notes:

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 & 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.
