  • Best Practices for Henkel Loctite 454

    *See Terms of Use Below

    1. Surface Preparation

      Bond areas should be clean and free from grease. Clean all surfaces with a Loctite® cleaning solvent and allow to dry.

      To improve bonding on low energy plastic surfaces, Loctite® Primer may be applied to the bond area. Avoid applying excess Primer. Allow the Primer to dry.

      LOCTITE® Activator may be used if necessary. Apply it to one bond surface (do not apply activator to the primed surface where Primer is also used). Allow the Activator to dry.

    2. Application

      Apply adhesive to one of the bond surfaces (do not apply the adhesive to the activated surface). Do not use items like tissue or a brush to spread the adhesive. Assemble the parts within a few seconds. The parts should be accurately located, as the short fixture time leaves little opportunity for adjustment.

      LOCTITE® Activator can be used to cure fillets of product outside the bond area. Spray or drop the activator on the excess product.

      Bonds should be held fixed or clamped until adhesive has fixtured.

      Product should be allowed to develop full strength before subjecting to any service loads (typically 24 to 72 hours after assembly, depending on bond gap, materials and ambient conditions).

    3. Curing

      Under normal conditions, the atmospheric moisture initiates the curing process. Although full functional strength is developed in a relatively short time, curing continues for at least 24 hours before full chemical/solvent resistance is developed.

      Cure Speed vs. Substrate: The rate of cure will depend on the substrate used.

      Cure Speed vs. Bond Gap: The rate of cure will depend on the bondline gap. Thin bond lines result in high cure speeds, increasing the bond gap will decrease the rate of cure.

      Cure Speed vs. Humidity: The rate of cure will depend on the ambient relative humidity. The best results are achieved when the relative humidity in the working environment is 40% to 60% at 22°C. Lower humidity leads to slower cure. Higher humidity accelerates it, but may impair the final strength of the bond.

      Cure Speed vs. Activator: Where cure speed is unacceptably long due to large gaps, applying activator to the surface will improve cure speed. However, this can reduce ultimate strength of the bond and therefore testing is recommended to confirm effect.

    4. Clean-Up

      Excess adhesive can be dissolved with Loctite cleanup solvents, nitromethane or acetone.
