LOCTITE® Product 454 is fast curing, single component gel
cyanoacrylate adhesive. It is specifically formulated for difficult
to bond substrates. The gel consistency prevents adhesive
flow even on vertical surfaces.
TYPICAL APPLICATIONS
Rapid bonding of a wide range of metal, plastic or elastomeric
materials, particularly suited for bonding porous or absorbent
materials such as wood, paper, leather or fabric.

TYPICAL CURING PERFORMANCE
Under normal conditions, the surface moisture initiates the
hardening 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 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 (14.5 psi) tested
according to ASTM D1002.

Substrate Fixture Time, seconds
Steel (degreased) 5 to 20
Aluminium 2 to 10
Zinc dichromate 10 to 20
Neoprene <5
Nitrile rubber <5
ABS 2 to 10
PVC 2 to 10
Polycarbonate 10 to 40
Phenolic materials 2 to 10
Cure speed vs. bond gap
The rate of cure will depend on the bondline gap. High cure
speed is favoured by thin bond lines. Increasing the bond gap
will slow down the rate of cure.
Cure speed vs. humidity
The rate of cure will depend on the ambient relative humidity.
The following graph shows the tensile strength developed with
time on Buna N rubber at different levels of humidity.

Cure speed vs. activator
Where cure speed is unacceptably long due to large gaps or
low relative humidity applying activator to the surface will
improve cure speed. However , this can reduce the ultimate
strength of the bond, 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 oxidising materials.

Directions for use
For best performance surfaces should be clean and free of
grease. This product performs best in thin bond gaps,
(0.05mm). Excess adhesive can be dissolved with Loctite
clean up solvents, nitromethane or acetone.
Storage
Product shall be ideally stored in a cool, dry location in
unopened containers at a temperature between 8°C to 21°C
(46°F to 70°F) unless otherwise labelled. Optimal storage
conditions for unopened containers of cyanoacrylate products
are achieved with refrigeration: 2°C to 8°C (36°F to 46°F).
Refrigerated packages shall be allowed to return to room
temperature prior to opening and use. To prevent
contamination of unused product, do not return any material to
its original container.
