Permabond

920 High-Temperature Cyanoacrylate Adhesive, Clear

In Stock

Permabond® 920 is the original allyl cyanoacrylate adhesive. It is a single-part, low-viscosity liquid that will cure rapidly at room temperature when pressed into a thin film between parts. Permabond 920 will cure to fixture strength in 10 seconds on most surfaces and rapidly develops high strength with a full cure obtained in 24 hours. The adhesive was specifically designed to meet the high-temperature resistance required by certain applications. It provides excellent bond strength to steel, aluminum, and most metal surfaces. The cyanoacrylate will also adhere well to a wide variety of other materials including most types of plastic and rubber.

Más información

To withstand high-temperature environments, Permabond® 920 was designed with a secondary curing mechanism that is activated at temperatures higher than 150°C (302°F). The procedure to activate this mechanism is as follows:

Parts are bonded and clamped at room temperature for four hours.
The clamped parts are then heated at 150°C (302°F) for two hours.
After the two hours, the bond will be thermally resistant up to 250°C (482°).

Physical Properties of Uncured Adhesive

Chemical composition: Allyl cyanoacrylate
Appearance: Colourless
Viscosity @ 25°C: 80 mPa.s (cP)
Specific gravity: 1.1

Typical Curing Properties

Maximum gap fill: 0.15mm (0.006")
Fixture/handling time* (0.3 N/mm² shear strength is achieved)
- 15-20 seconds (Steel)
- 10-15 seconds (Buna N Rubber)
- 10-15 seconds (Phenolic)
Full strength 24 hours

*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.
