Permabond 922 High-Temperature Max. Gap Fill Cyanoacrylate Adhesive, Clear, 1 oz. Bottle

To withstand high-temperature environments, Permabond® 922 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: 1,200-2,000 mPa.s (cP)

Specific gravity: 1.1

Typical Curing Properties

Maximum gap fill: 0.4mm (0.017″)

Fixture/handling time* (0.3 N/mm² shear strength is achieved):

<20>

<15>

<45>

<45>

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.

Typical Performance of Cured Adhesive

Shear strength* (ISO4587): Steel 19-23 N/mm² (2800-3300 psi)

Impact Strength (ASTM D-950): 3-5 kJ/m² (1.4-2.4 ft-lb/in²)

Hardness (ISO868): 85 Shore D

Coefficient of thermal expansion: 90 x 10^-6mm/mm/°C

Coefficient of thermal conductivity: 0.1 W/(m.K)

*Strength results will vary depending on the level of surface preparation and gap.
**SF = Substrate failure
