Three Bond Anaerobic Adhesives

Three Bond 1344E

Anaerobic Adhesive Sealant / Low Strength

The product Three Bond 1344E is a one-component, anaerobic reactive adhesive sealant without solvents, specifically designed for the assembly of medium-sized screws and threads. 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 completely adapts to the surface structure of the mating surfaces. All roughness in the micro-range, such as machining grooves and scratches, as well as irregularities in the macro-range (surface waviness), are filled, ensuring absolute conformity. The highly resistant chemical properties and good cohesion simultaneously achieve high strength within the adhesive sealant.

Features:

  • Being one-component and solvent-free, it can be excellently applied using fully automated dosing systems from Musashi.
  • Anaerobic curing begins immediately after the assembly of mating parts due to air exclusion and metal contact (suitable for nearly all metals).
  • Since solidification does not occur due to heat, assembled parts can be easily separated during machine repairs.
  • Excellent chemical and thermal resistance, along with outstanding resistance to vibrations and shocks due to its good mechanical properties.

Curing Conditions:

The curing speed depends on the type of surface. Active surfaces such as 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, chromium, zinc chromate, and titanium lead to significantly slower curing.

It should be noted that the gap between surfaces also affects the required time for complete curing.
