LOCTITE SF 7090 is a dark blue-green, low viscosity, reactive monomer-based, solvent-free surface activator composed of copper salt and aliphatic amine which increases the cure speed of LOCTITE anaerobic products. It is especially recommended for applications with passive metals or inert surfaces, with large bond gaps or where prevailing temperatures are as low as <+59 °F (<+15 °C).

  • Low viscosity
  • Solvent-free
  • Especially recommended for applications with passive metals or inert surfaces
  • Also recommended for large gaps
  • Suitable where prevailing temperatures are as low as <+59 °F (<+15 °C)
LOCTITE® SF 7090™ is a reactive monomer based "solvent
free" surface activator designed to promote the cure speed of
anaerobic products. It is especially recommended
for applications with passive metals or inert surfaces and with
large bond gaps. LOCTITE® SF 7090™ is particularly
recommended when prevailing temperature is low (<15 °C).

This product is not recommended for use in pure oxygen
and/or oxygen rich systems and should not be selected as
a sealant for chlorine or other strong oxidizing materials.
For safe handling information on this product, consult the
Safety Data Sheet (SDS).
Under no circumstances should activator and adhesive be
mixed directly as liquids. Use only in a well ventilated area.
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.
Directions for use:

  1. 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. The activator will not dry and will remain active for up to 1
    hour after application.
  3. Apply the Loctite anaerobic product to one or both
    surfaces and assemble parts immediately.
  4. Where possible, move surfaces in relation to each other
    for a few seconds on assembly to properly distribute the
    adhesive and for maximum activation..
  5. Secure the assembly and await fixturing before any
    further handling..
