Technical Datasheet Natural and synthetic rubber bonding Ideal for hard-to-bond plastics Ease of use - no mixing or heat-cure Bonds most materials 100% reactive - no solvents Approved to MIL-A-46050C Type II Class 1 (existing designs) PERMABOND® 105 is a low-viscosity, high-purity cyanoacrylate adhesive. It is ideal for use on hard-to-bond plastics and rubbers such as natural rubber, EPDM and butyl rubber. 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. *Strength results will vary depending on the level of surface preparation and gap. Typical Physical Properties of Uncured Adhesive Hot Strength Chemical composition Typical Curing Properties Maximum gap fill *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. 24-hour cure at room-temperature and conditioned to pull-temperature for 30 minutes before testing. Permabond® 105 can withstand higher temperatures for brief periods (such as for paintbaking and wave soldering processes) provided the joint is not unduly stressed.

PERMABOND® 105 Cyanoacrylate Technical Datasheet 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. Apply the adhesive sparingly to one surface. Bring the components together quickly and correctly aligned. Apply sufficient pressure to ensure the adhesive spreads into a thin film. Do...
