Permabond Cyanoacrylate (Instant) Adhesives
The excellent performance and versatility of Permabond's cyanoacrylate adhesives have eliminated many product design and production limitations. Permabond manufactures a full spectrum of cyanoacrylates. Our chemists have perfected this line to perform superbly with hard to bond materials such as polypropylene, polyethylene, PTFE and other polyolefins. Cyanoacrylates are also good for bonding materials such as metal, rubber, composite, phenolic, silicone and many more substrates.
Permabond's high performance cyanoacrylate formulations provide a wide variety of viscosity choices as well as non-blooming and low odor formulations, rapid cure formulas and high temperature resistant products.
How Do Cyanoacrylate Adhesives Work?
Permabond's cyanoacrylates (one-part adhesives) have been designed to cure by reacting to small traces of surface moisture. Because not all applications require the adhesive between two surfaces, Permabond developed an activator for use when the cyanoacrylate is left exposed. Simply spray the activator on the exposed adhesive. Cyanoacrylates cure very quickly at room temperature, eliminating the need for costly ovens or curing equipment. Gap fill ranges for cyanoacrylates are 0.015 cm (0.006") to 0.5 cm (0.02"). Temperature resistance ranges from -60 to +260°C (-75 to +500°F). Application possibilities for Permabond cyanoacrylate bonding include wire tacking and tamper proofing. Our research and development team continually pushes the limits of cyanoacrylate technology.

High Temperature Resistance
Permabond products 919 and 920 offer extremely high temperature resistance with a post secondary heat cure. Permabond 820 offers the highest temperature resistance the technology will bear without a secondary heat cure.
No Drip Gel
Permabond manufactures a true gel adhesive. This product is not simply thick but a highly thixotropic gel designed for applications that require the adhesive to stay where it is put without running or flowing. The product bonds to a wide variety of substrates and is ideal for vertical applications.
Non-Blooming and Low Odor
Permabonds 940 series is virtually odor free and will not fog or discolor plastics like conventional cyanoacrylates. Unlike other low odor cyanoacrylates Permabond 940 series are fast curing and offer high bond strengths to a variety of substrates.
Impact Resistance
Impact resistant Permabond 731 and 735 rapidly form excellent bonds to a variety of surfaces including aluminum, steel, plastics and rubbers and offer the ultimate impact resistance and peel strength. Although designed for flexible substrates, the added flexibility and toughness allows even greater shear strengths to steel and other rigid materials. Permabond 735 is opaque black and Permabond 731 is crystal clear. Both products are ideal for bonding applications that involve impact, peel and flexing stresses.
