Anaerobic resin: fixing, sealing and industrial assembly

What is an anaerobic resin?

La anaerobic resin is a single-component technical adhesive that cures in the absence of air (in an anaerobic environment) and in contact with metals. It is used forthread sealingthe bearing mounting and theprecision mechanical assembly. 

Unlike conventional adhesives, anaerobic resin remains liquid in the open air and only hardens when confined between two metal surfaces. This property gives it unique advantages in terms of mechanical strength, watertightness and protection against vibration. 

Advantages of anaerobic resins

  • Perfect sealing of threads and fittings prevents leaks of fluids, gases and oils 
  • Durable fixing of mechanical components prevents loosening under vibration 
  • Protection against corrosion thanks to non-shrink polymerisation 
  • Versatile applications bonding, fixing, assembly 
  • Compatible with most metals : steel, stainless steel, aluminium, brass 
  • Time-saving and easy to use direct application without mixing 

La anaerobic resin has established itself as a standard in industrial sectors requiring reliability, safety and productivity. 

Sealing of threads and hydraulic connections 

  • Anaerobic thread sealing resin for high-pressure seals 
  • Replacing PTFE tapes or traditional sealing pastes 
  • Compatible with oils, gases, fuels and industrial solvents 

Fixing and mechanical assembly 

  • Bearing mountingbushings, pins or pins 
  • Maintaining assemblies subjected to vibration or cyclic loads 
  • Replacement of mechanical locking systems such as washers or pins 

Industrial bonding and assembly 

  • Anaerobic resin bonding assembly for metal parts 
  • Locking screws, bolts or nuts in machine assembly 
  • Fastening of parts on production lines or in industrial maintenance 

Anaerobic thread sealing resin 

Fluid or medium viscosity formulation, ideal for protection of threaded connections against fluid or gas leaks. 

Anaerobic resin for fixing bearings 

High-strength formulation, perfect for assembly of bearings on shafts or mechanical housings. Prevents play and wear. 

Anaerobic resin bonding and assembly 

Used for blocking of metal partsfor securing pins or shafts, with high mechanical resistance properties.

FAQ - Anaerobic resin

It polymerises in the absence of air when confined between two metal parts, forming a solid, airtight seal.

A specific formula for waterproofingviscosity, adapted to the pressure and the type of fluid used. Our experts can advise you on the right viscosity.

Yes, depending on the resistance selected: low, medium or high. Some references require controlled heating for disassembly.

Varies according to temperature and substrate: initial setting in 5 to 20 minutes, complete polymerisation in 24 hours.

No, it is designed for metals. On plastics, it may not polymerise properly or may damage the material.
