Loctite 754 Extend Rust Treatment is a fast drying, milky white liquid latex coating applied to rusted metal to stop rust, protect and act as a primer for a finish coat. It is satisfactory for exterior exposure without a topcoat in mild environments. A maximum of two coats is recommended and allow seven to fourteen days for drying and curing. Severe environments require a suitable topcoat.

TYPICAL ENVIRONMENTAL RESISTANCE
Rust Treatment is satisfactory for exterior
exposure without a topcoat in mild environments. Two coats
maximum are recommended. A 7 to 14 day drying and curing
time is recommended. For severe environments, a suitable
topcoat is required.
USE AND APPLICATION
Loose or “flaky” rust must be removed. Only conversion of
firmly bonded rust will result in durable protection. Oil, grease,
old paint, mill scale, form oil, fingerprints and water soluble
surfaces and chlorides must be removed to allow Loctite®
Rust Treatment to react with rust. Loose rust, mill scale and oil paint should be removed
preferably by power wirebrushing, followed by rinsing with
water to remove powder and solubles. Manual wirebrushing,
chipping, scraping and particularly rotopeening can also be
used. Oil, grease, form oil and fingerprints should be removed before loose rust. Ideal surfaces will show light rust as well as
bare metal surfaces.
Rust Conversion Time and Appearance:
Two coats of Loctite® Extend®
Rust Treatment are
On lightly rusted steel (that has been wirebrushed), the first
coat will start to develop a violet color within 60 seconds. This will become satin to flat black in appearance. The second coat
should dry to a satin black appearance.
On heavily rusted steel (that has been wirebrushed), the first
coat should develop a purple-black color within seconds. The
second coat should dry to a black color with gloss varying from flat to satin. The second coat should be applied within 15 to 30
minutes of the first coat.
Directions for Use
- Mix thoroughly before using.
- Remove oil, dirt and grease from surface. Wire brush to
remove flaky rust and loose scale. Some surface rust
must be present
- Pour into clean container for easy application by brushing or apply directly to surface and brush out.
- Use of gloves is recommended.
- Brush or sponge on liberally. An airless spray may also
- A black coating will appear within 5 minutes. Uneven
color indicates need for additional coats for maximum
protection. Recoat time 15 to 30 minutes. Allow 24 hours
minimum to dry before finish paint.
- Most finish paints will not require any additional primer.
However, light color latex and metal filled paints require a
solvent base primer on top of Loctite®
Treatment coating before finish application.
- Brushes, rollers and other tools should be cleaned
immediately with detergent and water. Flush spray
equipment immediately after use with detergent and water.
Rust Treatment is difficult to remove
Hints and Precautions for Use
- Surface preparation - remove loose or flaky rust, oil,
grease, dirt, oil debonding paint, water soluble sulfates,
chlorides, cutting oil residues
- If sandblasted, sufficient material should be applied to effectively cover the profile
- Application of 2 coats for 4 mils dry film thickness
recommended for maximum durability.
- Prolonged contact with water before fully cured may cause
coating to turn white. After re-drying black appearance will
Rust Treatment may be applied when surface
and air is between 50ºF minimum and rising and 90ºF
maximum and falling. 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®
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 surfaces may be damp but not wet (i.e.continuous visible film of water). Do not apply Loctite®
Rust Treatment to surfaces in direct sunlight.
Application Equipment Methods
Rust Treatment may be applied by brush,
roller or spray. Brush or roller is suitable for small areas.
Avoid sags and ridges and keep wet by coating about a square
yard at a time. Roll away from previously coated area then roll
back. Do not pour unused material back into the original
container or dip brushes in original container. NEVER add
solvents to Loctite®
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®
Treatment may require thinning up to 10% with water for
Resistance to Moisture Solvents & Chemicals
Rust Treatment should be topcoated for many
applications. Continuous exposure of Loctite®
Treatment coating to water, solvents or chemicals can cause
whitening, blistering or flaking of the latex film.
Rust Treatment should not be used in
applications involving continuous immersion in water or fluids.
Extend® Rust Treatment should be topcoated with
products known to be resistant to the environment expected.
Latex topcoats are not recommended without a suitable barrier
Topcoat selection is dependent upon the environment to which
the coating will be subjected. The following guidelines can be
used. Topcoats are listed by their relative order of
- Moisture/salt spray - high-build epoxies, coal tar epoxies,
catalyzed urethanes, vinyls, chlorinated rubber
- Solvent Resistance - catalyzed urethanes, high build
epoxies, coal tar epoxies, vinyls
- Acid Resistance - catalyzed urethanes, vinyls, coal tar
epoxies, high build epoxies
- Alkali Resistance - catalyzed urethanes, coal tar epoxies,
high build epoxies, chlorinated rubber
- Oxidizing Agent Resistance - vinyls, catalyzed urethanes
- Abrasion - epoxies, urethanes, alkyds
two coats of Loctite®
Rust Treatment by a high build
primer or topcoat with sufficient mil thickness to prevent pinpoint corrosion. As with all paint systems, a test patch is
recommended. Any reputable painting contractor or coating
representative can also assist you.
The following primers should not be applied directly over
- Zinc dust (zinc rich primers)
- Copper powder (anti-fouling paints)
- Industrial primers containing chromate are usually
compatible, however a test patch should be completed to
Rust Treatment dries, it is extremely
difficult to remove; therefore, spatters should be cleaned as
they occur. Immediately after use, contaminated brushes,
rollers, trays, etc., should be cleaned with cold tap water and
detergent. Spray equipment should be flushed through
immediately with mild detergent and water and rinsed with
fresh water. Containers should be closed after every use to
If Loctite® Extend®
Rust Treatment is spilled on clothes, the
garment should be soaked with cold tap water as soon as
possible and Loctite®
Rust Treatment washed out
before it dries. Do not use ammonia, strong alkali detergents
or hot water for clean up.
Hands and nails should be cleaned with soap and water using
a nail brush. Black stains from iron-contaminated Loctite®
Rust Treatment can be removed from the hands with
a mixture of 1 volume of liquid household bleach and 4
volumes of tap water, followed by washing with soap and
water. Spills of Loctite® Extend®
Rust Treatment should be
flushed with large amounts of cold tap water.
Once dried, strong solvents such as paint remover will be required to
remove Loctite® Extend®
Rust Treatment from equipment and clothes.

solution with the adhesive. In some cases these aqueous washes can
affect the cure and performance of the adhesive.
