  • Best Practices for Henkel Loctite SF 7649

    *See Terms of Use Below

    1. Surface Preparation

      Where aqueous washing systems are used to clean the surfaces before bonding, it is important to check for compatibility of the washing solution with the adhesive. In some cases these aqueous washes can affect the cure and performance of the adhesive.

      Spray or brush on the activator on both mating surfaces to be bonded. For small gaps, treatment of only one surface may be adequate. contaminated surfaces may need repeated treatment or special degreasing prior to activation to remove any dissolvable contamination. Porous surfaces may need two treatments of activator.

    2. Application

      Spray or brush on the activator on both mating surfaces to be bonded. For small gaps, treatment of only one surface may be adequate. Contaminated surfaces may need repeated treatment or special degreasing prior to activation to remove any dissolvable contamination. Porous surfaces may need two treatments of activator.

      Allow the solvent time to evaporate under good ventilation until the surfaces are completely dry.

      After activation, parts should be bonded within 1- month. Contamination of the surface before bonding should be prevented.

      Apply the Loctite Anaerobic product to one or both surfaces and assemble parts immediately.

      Where possible, move surfaces in relation to each other for a few seconds on assembly to properly distribute the adhesive and for maximum activation.

      Secure the assembly and await fixturing before any further handling.
