Bonding metal to metal

Anaerobic adhesives are one-component adhesives with an acrylate base, used specifically to bond metal to metal. They are therefore very useful for a number of different industrial applications, for sealing against, for example, gas, air, water, oils or chemicals. 

Anaerobic adhesives with many uses

Anaerobic adhesives are very powerful partly because they only cure when the adhesive is applied in a closed joint, i.e. in contact with active metal ions, and in the absence of oxygen. They are therefore excellent for transferring shear loads in applications involving, for example, pipe sealing, flange gasketing, screw locking, bonding of bushings and bearings, and other types of cylindrical joints. 

Choose the right anaerobic adhesive for your bolted joint 

When you need to bond metal to metal, it is usually a strong or medium-strength anaerobic adhesive that is needed for your locking or sealing. At Tribotec we offer a wide range of adhesives for this purpose, with slightly different properties and specialisations.
The following tips may be useful to keep in mind when selecting anaerobic adhesives for your specific needs:

• Review the threads of your application to determine what viscosity your anaerobic adhesive needs to be. We offer both for example high-viscosity adhesive for medium-strength thread sealing:
  and low-viscosity adhesive for medium-strength thread sealing.
• Depending on the metal to be bonded, the adhesive has different curing times. To bond copper, bronze, brass - or hot metals - the adhesive needs to have a fast curing time. For example, we offer Loxeal 55-37 for sealing copper and brass. 
• Bonding black steel requires a medium-fast curing time
• Stainless or acid-resistant steel needs an anaerobic adhesive with a longer curing time.
• You can also use an activator to bond metal to metal, to speed up the curing time. Our spring Loxeal Activator also works great as a cleaner and primer.
