LOCTITE® 480 is an instant adhesive designed for the assembly of difficult-to-bond materials which require uniform stress distribution and high tensile and/or shear strength. It is a rubber-reinforced adhesive offering increased flexibility and peel strength along with enhanced shock resistance. The product provides rapid bonding for a wide range of materials, including metals, plastics and rubbers. LOCTITE 480 exhibits good resistance in humid environments.

• For applications where shock resistance is required or shock or peel loads are present
• Ideal for bonding metal to metal, to rubber or magnets
• Good resistance in humid environments

LOCTITE®
480™ is a rubber toughened adhesive with
increased flexibility and peel strength along with enhanced
resistance to shock.

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.
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,
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. For best performance bond surfaces should be clean and
   free from grease.
2. This product performs best in thin bond gaps (0.05 mm).
3. Excess adhesive can be dissolved with Loctite cleanup
   solvents, nitromethane or acetone.
