  • This product has a speed of 20 minutes at 20°C.
  • This adhesive has a viscosity of 1200 – 5000.

How to apply low strength thread locker 1225 purple

Once applied, low strength thread locker 1225 purple only cures when confined between the two mating metal parts. Before dispensing, ensure that surfaces are clean, dry and free of any dirt, dust and grease. For the best results, we recommend using CTA IPA Cleaner Degreaser. If the metal is inactive, apply CTA primer or UV identifiable primer.

  • The ideal application temperature is between 21 – 40°C.
  • Shake the product thoroughly before application.
  • Apply the adhesive to the fixing position of the fastener or onto the internal threads of a blind hole.
