PERMABOND 731 Toughened Cyanoacrylate Adhesive
PERMABOND 731 is a toughened and flexible cyanoacrylate adhesive designed to provide excellent impact and peel strength, outperforming conventional cyanoacrylates. This product is a 100% reactive, solvent-free adhesive that cures rapidly at room temperature. It's ideal for a wide range of applications due to its robust bonding capabilities on various materials, including metals, plastics, and elastomers.
Key Features & Benefits
-
Toughened and Flexible Formula: Offers superior impact and peel strength for more durable bonds.
-
Rapid Room Temperature Cure: Bonds quickly without the need for heat or special equipment.
-
User-Friendly: Comes ready to use with no mixing required.
-
Versatile Bonding: Effectively adheres to most materials, including steel, aluminum, galvanized steel, Buna N rubber, ABS, and neoprene.
-
Longer Cure Time: The slightly longer cure time compared to standard cyanoacrylates allows for accurate alignment of parts.

Directions for Use
-
Ensure surfaces are clean, dry, and grease-free. For best results on metals like aluminum, lightly abrade the surface to remove oxide layers.
-
Apply a sparing amount of adhesive to one surface.
-
Bring components together quickly and with accurate alignment.
-
Apply sufficient pressure to spread the adhesive into a thin film.
-
Do not disturb the bond until sufficient strength is achieved (in seconds). Full strength is reached in 24 hours.
Note: For difficult or porous surfaces, using a Permabond activator is recommended. To bond polyolefin materials (polypropylene, polyethylene, PTFE, silicone), prime the surface first with Permabond Polyolefin Primer (POP).
