Q:How can Loctite® brand Adhesive/Sealants improve the
quality of service repairs for my customers?
A: Quality service repairs with Loctite® brand products
do the following:
1. P
revent fasteners from loosening. Use Loctite® 242®
Threadlocker – Medium Strength liquid or Loctite®
QuickStix® 248™ Threadlocker.
2. Seal leaky threaded fittings. Use Loctite® Low
Breakloose PST® Thread Sealant liquid or Loctite®
QuickStix® 561™ PST® Pipe Sealant.
3. K
eep bearings from spinning out. Use Loctite® 609™
Retaining Compound.
4. Restore fit between worn bearings, sleeves, gears,
pulleys. Use Loctite® 660™ Quick Meta­l® Retaining
Compound – Press Fit Repair.
5. Seal flanged assemblies. Use Loctite® Flexible or
High Temperature Flange Sealant.
Improve customer satisfaction with all of the
above! Don’t put your CSAs at risk with inferior
performing products.
Q:How do these adhesive/sealants work?
A:Applied as a liquid or a paste, they automatically
harden into a tough resin between metal threads or
close-fitting parts. They lock and seal after assembly.
Q: Can I get the parts apart?
A:Yes. Use a little extra elbow grease and ordinary
tools on fasteners. Use a bearing puller or a press for
bearings or sleeves. Heating at 550°F (288°C) will help
loosen parts. Take apart while hot.
Q: Can I re-use the parts?
A:Yes. Knock or blow off the loose particles and re-apply
the adhesive/sealant. Material can be removed by
wire brush, if necessary.
Q: How do I know which product to use?
A:Bottles or tubes are named to indicate usage.
For example: Threadlocker indicates use on
threaded fasteners.
Q: How do I clean the parts?
A: Clean with Loctite® 7649™ Primer N™.
Q: What happens if I apply adhesive sealant and it
doesn’t work?
A:Four things that could have happened:
1. Sufficient material was not applied to
fill the joint.
2. Insufficient time was allowed for cure.
3. Parts were excessively oily, dirty or greasy, which
may prevent the adhesive/sealant from curing.
4. The surfaces required a primer before the adhesive/
sealant was applied.
Q: What should I do then?
29
A:Clean all parts thoroughly, using a wire wheel or a
putty knife and a solvent. When all parts are clean
and dry, apply Loctite® 7649™ Primer N™. Let it dry,
then apply the adhesive/sealant. Allow sufficient
time to cure.
Q: Will hydraulic oil, motor oil, fuel or water dissolve the
adhesive/sealant?
A:No. These adhesive/sealants are solvent-resistant to all
ordinary liquids and gases.
Q:How do I apply adhesive/sealant?
A: Simply apply from bottle nozzle or tube to one part.
Apply sufficient amount to fill the gap between parts. An
adhesive/sealant will not harden while in contact with air
– it hardens only in the joint after assembly.
Q: What happens if I leave the cap off a bottle or
tube of anaerobics (threadlocking, thread sealant,
gasketing, retaining)?
A:Nothing. It won’t harden in the tube or bottle
or evaporate.
Q: Where can I use Loctite® High Temperature
Flange Sealant?
A:Rigid flanges such as hydrostatic transmission
flanges, flywheel housings and other rigid covers
or plates. Use only where the change in joint
thickness will not affect internal clearances.
Q: Where do I use Loctite® Flexible Anaerobic
Gasket Flange Sealant?
A:It’s specified for sealing flywheel housings to the
block on series 3114, 3116 and 3200 engines. It is also
specified on differential steering systems on the D-6,
7, 8, 9 and 10 tractors.
Q: What do I use to seal track pins to track link bores
which may be scratched, scored or rusted on sealed
and lubricated track?
A:Loctite® High Flex Form-In-Place Gasket has
been successfully used in service to seal these
worn parts. Coat both the pin and bore, then
press together.
Q: Where can I use Loctite® brand RTV Silicone
Gasketing/Sealants?
Gasketing Applications
Q:How does Loctite® High Temperature Flange
Sealant work?
A:Loctite® High Temperature Flange Sealant forms
the gasket “in place”. When confined between the
assembled flanges, the gel-like material automatically
converts into a tough sealing gasket. It resists heat to
350°F (177°C). It also resists water, oil and solvents.
One tube makes many sizes and shapes of gaskets.
Q: How do I apply Loctite® High Temperature
Flange Sealant?
A: A
pply directly from the nozzle applicator on the tube.
No mixing. No heat cure. For most joints, apply a
1
/16" (1.59 mm) diameter bead around the bolt holes
and between the bolt holes centered on the flanges.
Material does not cure until flanges are mated
together. Be sure that the material will be in contact
with both flanges when parts are assembled.
Q:Can I get the flanges apart?
A: Yes. Tap on flanges to loosen.
A:Use for applications where a highly flexible
compound is needed for bonding, sealing,
weatherproofing or gasketing. Typical applications
are form-in-place gasketing at low pressures,
caulking of sheet metal duct work, sealing of
electrical boxes, insulating and sealing of electrical
wires and terminals, and potting (except around
electronic circuits). Use to insulate or seal metal,
glass, ceramic, painted and enameled surfaces, and
most plastics and rubber, including silicone rubber.
Cured sealant will not accept standard paint.
Q: Where do I use Loctite® 587™ Blue, High Performance RTV Silicone Gasket Maker?
A:Use as a general purpose silicone adhesive
sealant. It is the best silicone for oil resistance,
low odor, non-corrosiveness and low volatility.
Suggested for salvage operation sealing on minor
damaged flange surfaces at low pressures. Seals
gear covers, oil pans, valve covers, transmission
and PTO covers. Withstands temperatures to
400°F (204°C) continuous.
Q: What temperature will Loctite® Superflex® Red High Temp RTV withstand?
A:Loctite® Superflex® High Temp Red RTV bonds, seals,
gaskets, caulks, pots and insulates on applications
to 600°F (316°C). Use on applications that require
maximum heat resistance. Suggested for engines,
heat exchangers, air side of turbo chargers and
aftercoolers. Also bonds insulation for hard-wrap.
Q: How do I clean off the cured material?
A:For most flanged joints, it is not necessary to remove
the cured material. Wipe off surface with a clean shop
towel and apply a new bead, or if it is a very critical
dimension joint, remove all residue by scraping with
a putty knife or with a wire wheel. Then clean up with
Loctite® 7649™ Primer N™ before reassembly.

Threadlocking Applications
Bonding Applications
Q:How can I prevent “rusting in” between linkage pins
and cartridge pins and the mating bores?
A:Use Loctite® 242® or QuickStix® 248™ Threadlocker
to coat the pin and bore prior to assembly for a rustfree barrier. Applying Loctite® 242® or QuickStix® 248™
Threadlocker eliminates the need for burning out pins
on loader linkage arms, excavator sticks, and booms or
similar assemblies.
Q:On what bonding applications can I use the Loctite® Fixmaster® Fast Cure Epoxy?
Q:Are there any performance differences between
the new Loctite® brand Thread Treatment Sticks
(Loctite® 248™ and Loctite® 268™) and the traditional
Loctite® brand Threadlocker liquids (Loctite® 242®
and Loctite® 271™)?
A:No. Both of the new Loctite® brand Thread Treatment
Sticks were designed to maintain the exact
performance characteristics of the liquid alternatives.
A:Unlike epoxies, Loctite® 330™ Depend® Adhesive does
not require mixing, measuring or heating. Make sure all
parts are cleaned and dry. Spray activator, then apply
adhesive to parts that are to be assembled. Please see
the kit box for complete directions. Handling strength
in two minutes. Cures to tough powerful bond. Works
on all metals, wood, cork, ceramic, glass and most
plastics. May eliminate drilling, tapping, riveting or
welding. Easy syringe application. Oil resistant. Heat
resistant to 250°F (121°C).
Q:Is a primer, like Loctite® 7649™ Primer N™, necessary
when using threadlockers?
A:If the parts are contaminated with dirt and grease, they
should be cleaned with a primer in order to ensure
optimal performance. Other alternatives are to utilize
new threadlocking technology such as Loctite® 243™
Threadlocker – Oil Resistant. When the metals are
inactive, a primer should be used.
Q: Which Loctite® Threadlocker product is best suited
for a high shock or vibration application?
A: Loctite® 271™ Threadlocker – High Strength is best
suited for heavy equipment applications where shock
or vibration are common, such as suspension bolts,
motor, and pump mounts.
Q:How do I disassemble parts? What is the procedure?
A:Use standard hand tools for disassembly of low and
medium strength threadlockers. For high strength
threadlockers, apply localized heat to nut or stud for
5 minutes at 450°F (232°C). Disassemble while hot.
Q: What about preassembled fasteners? Is there a
Loctite® brand Threadlocker I can use to post-apply to
the assembly?
A:Yes. Loctite® 290™ Threadlocker – Medium Strength is
a wicking grade. This means that the Threadlocker can
be applied to preassembled fasteners and the liquid
will seep into the assembly to strengthen the fastener.
A:Use for bonding broken parts, patching holes and
resurfacing corroded areas (can be sanded or painted
after cure). Bonds metal, glass, wood, concrete
and some plastics. Bonds identification, name and
information plates. Fills large gaps.
Q:How do I use Loctite® 330™ Depend® Adhesive?
Q: What are some key applications for Loctite® 330™
Depend® Adhesive?
A:Use to bond name plates and serial plates on
equipment. Bonds control knobs that loosen under
vibration. Bonds dissimilar materials such as metal,
wood, plastic and concrete. Bonds porous surfaces.
Bonds glass to steel. Use to bond rear view mirror
brackets to windshields.
Q:How do Loctite® Fixmaster® Fast Cure Epoxy, Mixer Cups
differ from the other Loctite® brand adhesive products
previously described?
A:Loctite® Fixmaster® Fast Cure Epoxy, Mixer Cups have
two parts which must be mixed together. When mixed,
the epoxy will cure in air. Comes in a convenient mixer
cup for mixing. No mess. No guess. No waste.

Loctite® Extend® Rust Treatment may be applied when surface and air
are between 50°F and 90°F (10°C and 32°C). Reaction is slower at lower
temperatures. If temperature is too hot, film may surface dry and bubble.
High humidity is beneficial; it slows drying but assists rust conversion.
Loctite® Extend® Rust Treatment should not be applied in conditions of
condensing humidity (e.g., fog, dew), on ice, in rain or in heavy sea (salt)
spray atmospheres. Steel surface may be damp but not wet (i.e., continuous
visible film of water). DO NOT APPLY LOCTITE® EXTEND® Rust Treatment
TO SURFACES IN DIRECT SUNLIGHT.
APPLICATION EQUIPMENT METHODS:
Loctite® Extend® Rust Treatment may be
applied by brush, roller, or spray. Brush or
roller is suitable for small areas. Avoid sags
and ridges and keep edges wet by coating
about a square yard at a time. Roll away from
previously coated area and then roll back. Do
not pour unused material back into the original
container. NEVER add solvents to Loctite®
Extend® Rust Treatment.
Spray application is recommended for larger
areas. Airless spray equipment is faster, and
provides more effective conversion due to
improved surface penetration. Conventional
air-spray equipment may be used, but Loctite®
Extend® Rust Treatment may require thinning
up to 10% with water for proper spraying.

BONDING
INTRODUCTION TO BONDING ADHESIVES
SURFACE PREPARATION
Within the broad range of Loctite brand adhesives you will always
find the solution to your bonding challenge. It is, however, extremely
important to have at least basic knowledge of adhesive methodology in
order to successfully bond two substrates together. The three major
causes of bonding failures are attributed to:
Abrasive Methods
®
• Poor evaluation of the bonding assembly
Rubbing or striking a surface with hard, coarse material.
Abrasive examples:
• S
anding: Rubbing with abrasive paper or cloth (for small area/superficial
wear-down)
• B
lasting: Striking with steel grit, sand, or other abrasive material (for
large areas/deep wear-down)
• Inadequate substrate preparation
• Improper adhesive selection
Chemical Methods
BONDING ASSEMBLY
Bonding assembly has a direct impact in the adhesive performance. Choose
a combination of types of joints or joint stress distribution that maximizes
bonding strength. Below are different types of joints and stress distribution:
Cleaning process that uses solvents to dissolve contaminants.
Chemical examples:
• Solvent Dip: Immersing in solvent
• Solvent Wipe: Rubbing with solvent-soaked wipe
• Vapor Degreasing: Solvent in vapor form
TYPES OF JOINTS
• U
ltrasonic Cleaning: Solvent dip method with high-frequency sound
waves that vibrate the dirt away

JOINT WIDTH VS. OVERLAP
A wider bond line (Width) will be stronger than a lengthier one (Overlap):
1. Cut the starting end of the cord stock with a clean razor blade. Ensure
the cut is clean and square. Do not touch the clean cut end.
2. Measure cord stock to appropriate length. For precise measurement,
use Loctite® O-Ring Tool or the ruler provided in the Loctite® O-Ring
Making Kit.

OVERLAP
3. Cut the measured end of the cord stock with a clean razor blade.
Ensure the cut is clean and square to optimize bond area.
4. Apply one drop of Loctite® 404™ Quick Set™ Instant Adhesive and mate
the two ends of the cord stock.
