NSF International

Registered to NSF Category P1 for use as a sealant where
there is no possibilty of food contact in and around food
processing areas. Note: This is a regional approval. Please
contact your local Technical Service Center for more
information and clarification.
TYPICAL CURING PERFORMANCE

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. The table
below shows the fixture time achieved on different materials
at 22 °C / 50 % relative humidity. This is defined as the time to
develop a shear strength of 0.1 N/mm².
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.
Higher relative humidity levels result in more rapid speed of
cure.
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.
GENERAL INFORMATION

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).
Directions for use:


  1. Bond areas should be clean and free from grease. Clean
    all surfaces with a Loctite®
    cleaning solvent and allow to
    dry.
  2. 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.
  3. 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.
  4. 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.
  5. LOCTITE®
    Activator can be used to cure fillets of product
    outside the bond area. Spray or drop the activator on the
    excess product.
  6. Bonds should be held fixed or clamped until adhesive has
    fixtured.
  7. 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).
