Anaerobic adhesives & sealants are single-component type acrylic anaerobic adhesives and sealants. In addition to bonding and sealing of screws and interlocking parts, they can also be used for magnet surface adhesion, and bonding and sealing of metal materials. When air (oxygen) supply is cut between metal materials such as when a screw is tightened and the gaps of the threads are minimized, curing reaction begins due to the metal ions, and curing by polymerization occurs rapidly.

For screws, after around 20 seconds to a few minutes, it cures to where it cannot be moved (set time), and from 30 minutes to 2 hours it reaches 1/2 of final strength (practical strength). After 12 to 24 hours, it reaches final strength, and it forms a tough cured material with excellent oil resistance, chemical resistance, heat resistance, and weather resistance.

It can be used in a temperature range from -40°Cto 150°C (approx.) (200°C for heat-resistant type). There are also types with UV curability and primer curability in addition to anaerobic curing property.

TB1377B  is good for adhesion and sealing of interlocking portions such as pins, bushes, shafts, and bearings. It can be used in a temperature range from below -40°C to 120°C (150°C) (approx.).
