792 High-Temperature Surface Insensitive Fast Curing Cyanoacrylate Adhesive, Clear
Permabond® 792 is a low-viscosity, surface-insensitive adhesive that will rapidly bond substrates with acidic surfaces such as wood and plated surfaces. Plastics, metals, ceramics, and elastomers are also rapidly bonded. The fast cure minimizes the occurrence of frosting and fogging. 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.

Physical Properties of Uncured Adhesive
- Chemical composition: Ethyl cyanoacrylate
- Appearance: Colourless
- Viscosity @ 25°C: 60-125 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)
- 2-3 seconds (Steel)
- 2-3 seconds (Buna N Rubber)
- 2-3 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.
Typical Performance of Cured Adhesive
- Shear strength* (ISO4587):
- Steel 18-22 N/mm2 (2600-3200 psi)
- ABS 8 N/mm2 (1160 psi)**
- PVC >10 N/mm2 (>1450 psi)**
- Polycarbonate 10 N/mm2 (1450 psi)**
- Tensile strength (ISO6922): >20 N/mm2 (>3000 psi)
- Coefficient of thermal expansion: 90 x 10-6mm/mm/°C
- Coefficient of thermal conductivity: 0.1 W/(m.K)
- Hardness (ISO868): 85 Shore D
- Dielectric Strength: 25 kV/mm
*Strength results will vary depending on the level of surface preparation and gap.
