Three Bond Anaerobic Adhesives

Three Bond 1361B

Anaerobic adhesive sealant / Penetration Type

The product Three Bond 1361B is a one-component, solvent-free anaerobic reactive adhesive sealant. Due to its very low viscosity, it is particularly suitable for use in pre-assembled components. It is applied in liquid form at room temperature to one of the surfaces to be joined. After the assembly of the parts, a strong adhesive sealant is formed within a very short time, which fully adapts to the surface structure of the mating surfaces. All roughness in the micro-range, such as machining grooves and scratches, are filled as well as irregularities in the macro-range (surface waviness), ensuring absolute conformity. The highly resistant chemical properties and good cohesion simultaneously achieve high strength within the adhesive sealant.


  • The very low viscosity allows for deep penetration in pre-assembled components.
  • Extremely easy to dispense and apply due to being one-component and solvent-free.
  • Anaerobic curing begins immediately after the assembly of the mating parts through air exclusion and metal contact (almost all metals are suitable for this).
  • Since solidification through heat does not occur, joined parts can be easily separated during machine repairs.
  • Excellent chemical and thermal resistance, as well as outstanding vibration and impact resistance due to its good mechanical properties.

Curing Conditions:

The curing speed depends on the type of surface. Active surfaces like iron, nickel, and steel facilitate rapid curing. Surfaces like aluminum, brass, stainless steel, and zinc result in moderately fast curing, while inactive surfaces like cadmium, chrome, zinc chromate, and titanium lead to significantly slower curing.

It should be noted that the gap (or clearance) also affects the required time for complete curing.
