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.).
