Key Substrates Rubbers, Plastics and Metals
LOCTITE®382™ is a single part, fast curing high viscosity
cyanoacrylate adhesive formulated for electronics applications.
LOCTITE®382™ is designed to use with TAK PAK®
Accelerators to attain instant cures for tacking electronics
components . Typical applications include wire tacking to coil
forms; tamper proofing adjustable components; mounting
standoffs, edge guides and stiffeners to circuit boards.

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.
Fixture Time, seconds:
Steel (degreased) 20 to 50
Aluminum 10 to 30
Neoprene <5
Rubber, nitrile <5
ABS 15 to 40
PVC 20 to 50
Polycarbonate 30 to 70
Phenolic 10 to 40
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. 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. Apply one coating of TAK PAK® accelerator to the area to
be bonded, by spray, brush or dipping. Prior to
application, contaminated surfaces may need special
cleaning or degreasing to remove any dissolvable
contamination.
NOTE: Because the solvent base of TAK PAK® accelerators
can affect certain plastics or coatings, checking all surfaces for
compatibility is recommended.
.
2. Allow the accelerator time to evaporate under good
ventilation until the surfaces are completely dry (approx.
15 to 30- seconds)..
3. Apply LOCTITE®382™ cyanoacrylate product
immediately after solvent has dried.
NOTE: If cyanoacrylate is not applied to the accelerator within
45 seconds, accelerator should be reapplied
.
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..
