Technical Data Sheet
LOCTITE
®
7452™
November - 2008
PRODUCT DESCRIPTION
LOCTITE
®
7452™ provides the following product
characteristics:
Technology Cyanoacrylate Activator
Chemical Type Amine (active ingredient)
Solvent Acetone
Active Ingredient
Concentration, %
0.8 to 0.95 LMS
Appearance Transparent colorless to slightly
amber liquid LMS
Viscosity Very low
Cure Not applicable
Application CA adhesive cure accelerator
LOCTITE ® 7452™ is used where increased cure speed of
LOCTITE
®
cyanoacrylate adhesives is required. It can be
either pre- or post-applied to the bond. The product is
especially suited for post-application on cyanoacrylate
adhesive to ensure rapid fixturing. Typical applications include
securing wires or coils to PCBs, tamper-proofing adjustable
components, mounting stand-offs, edge guides and board
stiffeners.
TYPICAL PROPERTIES
Specific Gravity @ 25 °C 0.79
Viscosity @ 20 °C, mPa·s (cP) 0.3 to 0.5
Drying Time @ 20 °C, seconds ≤30
On Part Life, minutes ≤1
Infrared Spectrum To match standard LMS
Flash Point - See MSDS
TYPICAL PERFORMANCE
Fixture time and cure speed achieved as a result of using
LOCTITE
® 7452™ depend on the adhesive used and the
substrate bonded.
Fixture Time, ISO 4587, seconds:
Steel (grit blasted) using LOCTITE ® 495™,
two side activation
≤10 LMS
(Fixture time is defined as the time to develop a shear strength
of 0.1 N/mm²)
Handling precautions
Activator must be handled in a manner applicable to highly
flammable materials and in compliance with relevant local
regulations.
The solvent can affect certain plastics or coatings. It is
recommended to check all surfaces for compatibility before
use.
GENERAL INFORMATION
This product is not recommended for use in pure oxygen
and/or oxygen rich systems and should not be selected
with a sealant for chlorine or other strong oxidizing
materials.
For safe handling information on this product, consult the
Material Safety Data Sheet (MSDS).
Under no circumstances should activator and adhesive be
mixed directly as liquids. Use only in a well ventilated area.
Directions for use
Post Activation
1. Apply Loctite cyanoacrylate to the parts to be bonded or
fixed.
2. Apply Activator over all exposed cyanoacrylate adhesive
by spray or drop. (Typically use one drop of activator per
drop of exposed adhesive).
Surface Activation
1. Apply one coating of Activator to the area to be bonded by
spray, brush or dipping. Contaminated surfaces may need
special cleaning or degreasing prior to activation to
remove any soluble contamination.
2. Allow LOCTITE ® 7452™ to fully evaporate from parts
prior to bonding to avoid solvent entrapment within the
bond joint.
3. Apply the Loctite cyanoacrylate product immediately after
drying or not more than 45 - seconds thereafter.
4. Activator can be re-applied if necessary if there is a delay
of more than 45 - seconds between original activator and
adhesive application.
Loctite Material Specification LMS
LMS dated May - 19, 1998. Test reports for each batch are
available for the indicated properties. LMS test reports include
selected QC test parameters considered appropriate to
specifications for customer use. Additionally, comprehensive
controls are in place to assure product quality and
consistency. Special customer specification requirements may
