Three Bond Anaerobic Adhesives

Three Bond 1375B

Anaerobic adhesive sealant / assembly adhesive with high strength

The product Three Bond 1375B is a one-component, solvent-free anaerobic reactive adhesive sealant specially designed for fastening and sealing tight-fitting surfaces with low clearance. It is applied in liquid form at room temperature to one of the mating surfaces to be joined. After the assembly of the parts, a strong adhesive sealant is formed within a very short time, completely conforming to the surface structure of the mating surfaces. All micro-level roughness such as machining marks and scratches, as well as macro-level irregularities (surface waviness), are filled, ensuring absolute conformity. At the same time, the high-resistance chemical properties and good cohesion result in a high strength within the adhesive sealant.


  • As it is one-component and solvent-free, it can be easily applied with fully automatic dispensing systems.
  • Anaerobic curing begins immediately after the assembly of the mating parts due to air exclusion and metal contact (almost all metals are suitable for this).
  • Since solidification does not occur through heat, assembled parts can be easily separated during machine repairs.
  • Excellent chemical and thermal resistance as well as outstanding vibration and shock resistance due to its good mechanical properties.
