Anaerobic Adhesives and Sealants
Anaerobic Adhesives and Sealants: Anaerobics are one-component adhesives that remain liquid when exposed to air. When confined between metal substrates, they cure or harden into tough thermoset plastics that provide excellent resistance to environment and temperature. T hey cure in the absence of air, in presence of metallic ions. Available in a wide range of formulations, anaerobic adhesives are commonly used for locking and sealing threaded assemblies, as well as retaining bearings and bushings on shafts or in housings. They also seal metal flanges in place of cut gaskets. These materials are often applied to enhance or replace mechanical joining methods, resulting in longer equipment service life and reduced manufacturing costs.
Key Characteristics:
- Eliminates need for mechanical locking devices
- Single component
- Reduces inventory cost
- Evenly distributes load
- Augment press fits
- Enables assembly of dissimilar metals
Types of Anaerobic Adhesives:
- Threadlockers: Prevent vibration loosening and seal against leakage and corrosion. They eliminate the use of lock washers and various other fastening devices and take the place of a wide variety of traditional and sometime ineffective vibration proofing methods, reducing cost and increasing performance!
- Retaining Compounds: Used in the assembly of all coaxial components such as bearings, shafts, bushes, gears, pulleys, cylinder liners and rotors. They increase the load bearing characteristics of cylindrical joints, reducing assembly stresses, assembly costs and preventing fretting and corrosion.
- Hydraulic and Pipe Sealants: Designed for thread and pipe sealing, replacing traditional PTFE tapes and dopes. These products seal instantly and do not shred, evaporate or shrink. They resist pressure, vibration and temperature cycling as well as hydraulic fluids, oil, fuel and lubricants.
- Gasket Makers: These create formed-in-place gaskets on flanges and housings, eliminating the need for large inventories of pre-cut gaskets. Once cured, the product keys into the adjacent faces of the joint. They do not relax or shrink and have exceptional pressure and fluid resistance, such as petroleum solvents.
