2.
Primers speed cure times for faster return to service.
3.
Primers speed curing through larger gaps and deep threads.
4.
Primers substantially speed cure times on cold parts.
5.
Primers act as cleaning agents.

Note: Silicones used at extreme high temperatures can seal but lose various properties.
REASONS TO USE HIGH PERFORMANCE SILICONES INSTEAD OF STANDARD RTV SILICONES
•
LOCTITE® HIGH PERFORMANCE SILICONES WILL NOT CORRODE STEEL OR ALUMINUM. Standard RTV acetoxy silicones (vinegar smell) should not be used to seal closed systems (gear boxes, electrical boxes, etc.). Acetic acid will corrode internal parts (bearings, contacts, etc.).
•
LOCTITE® HIGH PERFORMANCE SILICONES ARE 8 TIMES MORE OIL RESISTANT THAN STANDARD RTV SILICONES. Standard RTV silicones should not be used to seal ”Hot Oil” systems (oil pan, etc.). They swell and lose sealing ability.
REASONS TO USE GASKET ELIMINATOR® INSTEAD OF STANDARD RTV SILICONES
•
LOCTITE® GASKET ELIMINATOR® IS RESISTANT TO GASOLINE AND FUEL OILS. Silicones should not be used to seal fuel systems. They swell and lose sealing ability.
•
LOCTITE® GASKET ELIMINATOR® RESISTS “BLOW-OUT”. Silicones are not recommended for high pressure applications.

BONDING
I. JOB EVALUATION — Answer These Questions.
A. What materials are to be bonded? What kind of rubber, plastic, etc.? Porous? Slick? Rough?
B. What kind of service? Operating temperature? Impact? Moisture or water exposure?
C. What kind of stresses? Avoid peel or cleavage!
D. Is gap filling or bridging needed? How much?
E. What cure speed or “return to service” time is needed?
II. ADHESIVE SELECTION (See page 33.)
III. SURFACE PREPARATION
1.
Part must be clean. No oil. No grease. No residue.
2.
Remove paint from bond area for maximum strength.
3.
Roughen smooth surfaces with emery cloth.
4.
Treat selected “hard to bond” materials as directed:
a.
Polyethylene, etc. – Use Loctite® Prism® Primer 770 or 793.
b.
PTFE – Use appropriate etching agent.
5.
Alcohol wipe parts cleaned with water-based “safety” cleaners.
IV.
APPLICATION TECHNIQUES/TIPS
A. Read and follow adhesive package instructions.
B. Use the minimum amount of adhesive to one part only.
Apply activator (if required) to other part.
C. Avoid “jiggling” mated parts. Apply clamp pressure if possible.
D. Allow maximum cure time possible. See technical data for
recommended cure times.

RUSTPROOFING
SURFACE PREPARATION — OLD STEEL:
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® Extend® 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® are recommended.
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 15-30 minutes of the first coat.
APPLICATION CONDITIONS:
Loctite® Extend® may be applied when surface and air is between 50°F minimum and rising and 90°F 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. Extend® 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® TO SURFACES IN DIRECT SUNLIGHT.
APPLICATION EQUIPMENT METHODS:
Loctite® Extend® 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 then roll back. Do not pour unused material back into the original container. NEVER add solvents to Loctite® Extend®.
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® may require thinning up to 10% with water for proper spraying.

CLEANING
In general, Natural Blue® cleaning effectiveness is enhanced by:
a.
Higher Natural Blue® Cleaner & Degreaser
concentrations;
b.
Longer cleaner on-part times;
c.
Dilution with warm water (150°F to 180°F);
d.
Agitation of parts or scrubbing.
DIRECTIONS
1.
Dilute Natural Blue® concentrate with water to most economical/effectiveness level. See package labels for suggested ratios.
2.
Spray, dip or wipe dilution onto parts or surface to be cleaned.
3.
Soak parts or scrub (if needed).
4.
Flush soil/cleaner mixture off of parts or surfaces with water.
5.
Disposal: Natural Blue® contains no hazardous ingredients. It should be disposed of in accordance with state and local regulations and will not harm sewage treatment microorganisms. Once Natural Blue® is mixed with hazardous waste, it must be treated as hazardous waste and disposed of accordingly.
Note: Loctite® ODC-Free Cleaner & Degreaser is recommended for cleaning substrates before Loctite® machinery adhesive use.
For fast, effective hand cleaning without skin-irritating petroleum solvents, use LOCTITE® ORANGE Natural Citrus Hand Cleaner. Available with or without pumice, in cream or lotion formula, LOCTITE® ORANGE waterless hand cleaner removes grease, grime, paint, oil and ink and contains aloe and lanolin to keep hands from cracking and drying out. It’s even biodegradable.
