Permabond has engineered an extremely quick setting adhesive that demonstrates a rapid development of high strength. Permabond 792 is proven easy to use, requiring no heat cure or mixing, and works on almost all surfaces. This material is 100% reactive, and it is not suggested for use in contact with polar solvents or strong oxidizing materials. Permabond 792 is a low viscosity adhesive ideal for rapidly bonding substrates that have acidic surfaces, including plated surfaces and wood. Also included in types of surfaces that bond rapidly using this adhesive are ceramics, metals, elastomers, and plastics.
The occurrence of fogging and frosting are minimized with the quick cure of Permabond 792 Surface Insensitive Adhesive. This single component Cyanoacrylate adhesive is able to polymerize quickly when it is pressed into a thin film between surfaces. The curing of Permabond 792 Surface Insensitive Adhesive is initiated by the moisture that is absorbed on the surface. This adhesive is a great choice for projects requiring a speedy cure and a strong bond on a variety of different materials. High speed production lines benefit tremendously from Permabond Cyanoacrylates.
The shear strength of Permabond 792 Surface Insensitive Cyanoacrylate Adhesive is Steel 18-22 N/mm² (2600-3200 psi), and the tensile strength is 17N/2mm² (2500 psi). The glass transition of this adhesive is 58°C (140°F), and its coefficient of thermal expansion is 90 x 10 ¯6 mm/mm/°C. The dielectric strength of Permabond 792 Surface Insensitive Cyanoacrylate Adhesive is 10 mV/mm, its coefficient of thermal conductivity is 0.1 W/(m.K), and its hardness is 85 Shore A. The chemical composition of this material is Ethyl Cyanoacrylate, and it is colorless in appearance. This adhesive’s viscosity is 70-90 mPa.s (cP) @25°C, and its density is 1.06. Additional technical data can be found on the Permabond 792 TDS.

As long as the joint is not excessively stressed, Permabond 792 is able to endure higher temperatures for short periods of time in cases such as wave soldering processes and paint baking. Prior to applying this adhesive, all surfaces should be grease-free, clean, and dry. To degrease surfaces, a solvent such as isopropanol or acetone should be used. Certain metals including copper, aluminum, and its alloys will be better off with light abrasion using an emery cloth or something similar to eliminate the oxide layer before using Permabond 792. In the case of a porous or difficult surface that requires bonding, it is suggested that a Permabond activator is used.

Permabond 792 Surface Insensitive Adhesive is a great option for jobs requiring a fast set, quick development of high strength, and surface insensitivity. This material is perfect for constructing high strength bonds on high speed production lines. Before opening the bottle, this adhesive should be given the time to reach room temperature first in order to prevent condensation on the inside of the container (condensation can cause a reduced shelf life).
