Technical Datasheet 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 PERMABOND® 947 is a low odour, non-fogging, nonfrosting 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. *Strength results will vary depending on the level of surface preparation and gap. Physical Properties of Uncured Adhesive Chemical composition Typical Curing Properties *Handling times can be affected by temperature, humidity and specific surfaces being bonded. Larger gaps or acidic surfaces will also reduce cure speed but this can be overcome by the use of Permabond C Surface Activator (CSA) or Permabond QFS 16. "Hot strength" shear strength tests performed on mild steel. 24hr cure at room temperature and conditioned to pull temperature for 30 minutes before testing. 947 can withstand higher temperatures for brief periods (such as for paint baking and wave soldering processes) providing the joint is not unduly stressed. The minimum temperature the cured adhesive can be exposed to is -55°C (-65°F) depending on the materials being bonded.

Chemical Resistance Surface Preparation % Strength Retention 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 aluminium, copper and its alloys will benefit from light abrasion with emery cloth (or similar), to remove the oxide layer. 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...
