Why Use Adhesives?
 Replace screws, nails, bolts, clamps,
rivets, welding, soldering, etc.
 Joint stress distributed evenly
through the joint
 No damage to substrates
 Bond and seal joints
 Reduces weight (number of
components) and cost
 Fast and convenient
 Most products have excellent fluid
resistance

RITE-LOK™ Cyanoacrylate Adhesives
Which grade?

Choose the correct grade for the substrate or application
Rubber – PR
High temperature – HT or RT
Wood - SI

Choose the viscosity. Does the application require:
LOW (5 cPs) - Post assembly (adhesive applied after final assembly)
MEDIUM (100 cPs) – Most applications
HIGH (1500 cPs) - Porous (most woods, foam rubber)
VERY HIGH (Gel) - Vertical or underside applications

RITE-LOK™ Cyanoacrylate Adhesives
Mechanism of RITE-LOK™ Cyanoacrylate Adhesive cure
An acidic stabiliser (red) keeps
cyanoacrylate liquid
Water particles (blue) on
the substrate surface
neutralise the stabiliser
Polymerisation begins and the
parts are bonded together

3M Industrial Adhesives and Tapes Division
RITE-LOK™ Cyanoacrylate Adhesives
Where not to use cyanoacrylate adhesives!
 Where the application will be submerged in water or constantly wet
These conditions can soften the adhesive and may cause failures
 Where there are low ambient humidity conditions
These conditions will slow down the curing process
 Cyanoacrylate adhesive will bond to glass, but failure is likely later
Silane based substrate where insufficient chemical bonds are made with the surface
of the glass
 Please remember!
 Thin bond lines give the strongest bond and cure most rapidly

RITE-LOK™ Anaerobic Range
What is an anaerobic adhesive?
 Anaerobic adhesives cure in the absence of oxygen and in the presence of metal
ions
 To keep the adhesive in a liquid state, an air space is left in the bottle and the low
density container allows air migration
How does an anaerobic adhesive cure?
Before assembly
AIR
After assembly
Solid
Liquid
Oxygen present - the
adhesive remains liquid
23
© 3M 2007. All Rights Reserved.
Oxygen excluded/the adhesive is in contact with
metal - the adhesive cures to form a tough, durable
plastic film which bonds and seals the joint
3M Industrial Adhesives and Tapes Division

RITE-LOK™ Anaerobic Adhesives
 RITE-LOK™ anaerobic adhesives will not cure on plastic
parts
No metal ions present to start the polymerisation process
 Do not use on oxygen/oxygen-rich or chlorine systems
Uncured anaerobic adhesive can be hazardous in these conditions
 Do not allow customers to apply anaerobic adhesives by
dipping or brushing parts
Metal particles will contaminate the adhesive in the container causing
polymerisation
 Any parts of dispensing machines which come into contact
with anaerobic adhesives must be manufactured from plastic,
PTFE or stainless steel

RITE-LOK™ UV Adhesives
 Check light penetration of substrates
One substrate must allow the passage of UV light!!
Some plastics only allow a little UV light penetration
Some substrates may contain UV absorbent films/chemicals
 Protect uncured adhesives from light
Keep the cap on the container when not in use
Keep in the supplied container
 Match the lamp wavelength to the photo-initiator of the product
This will ensure a tack-free surface for potting and coating applications
 Beware of shadow areas where the UV light can not penetrate to the
bond line
