Permabond 737
PERMABOND 737 Toughened Cyanoacrylate Adhesive
Permabond 737 is a toughened cyanoacrylate with improved impact and peel strength for maximum flexibility. Its increased temperature resistance and dark color make Permabond 737 suitable for a wide range of applications. It bonds rapidly to a variety of surfaces including aluminum, steel (both zinc-plated and uncoated), plastics and rubbers.
Features and Benefits
- Good gap fill (up to 0.5mm / 0.02”)
- Toughened and flexible
- Ease of use – no mixing or heat cure
- Black – so suitable for dark surfaces
- 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. 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.
Surface Preparation prior to bonding with Permabond 737
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 aluminum, copper and its alloys will benefit from light abrasion with emery cloth (or similar), to remove the oxide layer.
Permabond 737 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 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).
