Instant Adhesive Gel
October - 2005
PRODUCT DESCRIPTION
LOCTITE
® Quicktite ® Instant Adhesive Gel provides the
following product characteristics:
Technology Cyanoacrylate
Chemical Type Ethyl cyanoacrylate
Appearance (uncured) Transparent, colorless gel LMS
Components One part - requires no mixing
Viscosity Gel
Cure Humidity
Application Bonding
Key Substrates Wood, Paper, Leather and Fabric
LOCTITE ® Quicktite ® Instant Adhesive Gel is designed for
the rapid bonding of a wide range of materials, including
metals, plastics and elastomers. LOCTITE
® Quicktite ®
Instant Adhesive Gel is particularly suited for bonding porous
or absorbent materials such as wood, paper, leather and fabric.
The gel consistency prevents adhesive flow even on vertical
surfaces.
TYPICAL PROPERTIES OF UNCURED MATERIAL

Casson Viscosity, 25 °C, mPa·s (cP):
Cone and plate rheometer 100 to 450 LMS
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, ISO 4587, seconds:
Steel (grit blasted) 30
Neoprene 60
PVC 15
Paper ≤30 LMS
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.
Higher relative humidity levels result in more rapid speed 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
Material Safety Data Sheet (MSDS).
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.
