Three Bond Anaerobic Adhesives

Three Bond 1327

Anaerobic adhesive / Medium strength

The product Three Bond 1327 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 forms 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 (waviness of the mating surface), are filled, ensuring absolute conformity. The high-resistance chemical properties and good cohesion also simultaneously achieve high strength within the adhesive sealant.

Features:

  • Extremely easy to dispense and apply due to being one-component and solvent-free.
  • Anaerobic curing begins immediately after the assembly of mating parts through the exclusion of air and metal contact (suitable for almost all metals).
  • Since curing doesn't occur due to heat, assembled parts can be easily separated when repairing machines.
  • Excellent chemical and thermal resistance, as well as outstanding vibration and impact resistance, due to its excellent 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 cause moderately fast curing, while inactive surfaces like cadmium, chrome, zinc chromate, and titanium result in significantly slower curing.

It should be noted that the gap also increases the required time for complete curing.
