This Technical Data Sheet is valid for LOCTITE® 454™

manufactured from the dates outlined in the

"Manufacturing Date Reference" section.

LOCTITE® 454™ is designed for the assembly of difficultto-

bond materials which require uniform stress distribution and

strong tension and/or shear strength. The product provides

rapid bonding of a wide range of materials, including metals,

plastics and elastomers. The gel consistency prevents

adhesive flow even on vertical surfaces. LOCTITE® 454™ is

also suited for bonding porous materials such as wood, paper,

leather and fabric.

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.

Fixture Time, seconds:

Steel 30 to 60

Aluminum 2 to 10

Neoprene 10 to 15

Rubber, nitrile <5

ABS <5

PVC 5 to 10

Polycarbonate 10 to 15

Phenolic <5

Wood (balsa) <5

Wood (oak) 30 to 60

Wood (pine) 15 to 30

Chipboard 5 to 10

Fabric 10 to 20

Leather 5 to 15

Paper 5 to 10

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 best results are achieved when the relative

humidity in the working environment is 40% to 60% at 22°C.

Lower humidity leads to slower cure. Higher humidity

accelerates it, but may impair the final strength of the bond.

Cure Speed vs. Activator

Where cure speed is unacceptably long due to large'
