PERMABOND® 943 is a low odour, non-fogging, non- frosting alkoxyethyl cyanoacrylate. The reduced odour 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 odour for improved worker comfort
- Non-frosting –good aesthetic appearance
- Ease of use – no mixing or heat cure
- Bonds most materials
- 100% reactive, no solvents
