ThreeBond’s anaerobic 1300 series offers comprehensive solutions for bonding the joints of all types of threads, etc, preventing them from loosening or leaking.
They are different from ordinary adhesives and sealants by the fact that they remain liquid so long as they are in contact with air, and as they enter fine gaps in metal parts and become isolated from oxygen, they harden at normal temperature without shrinking.
The hardened adhesive is characterised by excellent vibration resistance, heat and chemical resistance, effectively bonding threads and joints and preventing loosening and leakage.
Each product is one-part, non-solvent based with good workability and easy use.
Typical applications are in thread locking of all types of bolts, studs etc, retaining nuts or sealing threaded joints, eg in hydraulic systems, practically anywhere and everywhere.
The 1300 series is suitable for fixing/sealing of motor shafts/rotors, pulley or gear fixing, location of bearings, bushes, sleeves, splines, tubes and Welch type core plugs. Indeed, so good is the fine capillary action that some 1300 anaerobic adhesive can even be applied after assembly.
Performance of the 1300 series is characterised by quick hardening at room temperature, little shrinkage, excellent oil, chemical, vibration and weathering resistance. Ease of use is greatly aided by good reactivity even on inert materials such as plated surfaces including zinc chromate chromium and nickel-chromium without the need for an activator.
Anaerobic adhesives and sealants (AAS) are broadly defined as compounds which polymerize and harden when isolated from air between two adjacent faces, so as to be suitable for locking metal parts, sealing and fastener fitting.
Upon polymerisation, AAS turns to resin of dense three-dimensional reticular structure, which has excellent anti-corrosiveness, solvent resistance, thermal resistance, and ageing resistance.
Since no solvent is involved, the polymerisation produces little contraction and so is extremely suitable for fixing and sealing of fittings, pipe and flanges.
The polymerisation of AAS requires three conditions: a. Isolation from air (oxygen); b. Contact with metal; c. Appropriate temperature. The reaction between peroxide and metal ion produces an initial radical to start the polymerisation. As a consequence of these complicated series of reactions, very strong three-dimensional reticular structures are formed.
