LOCTITE Silver Grade Anti-Seize Lubricant is a heavy-duty, high-temperature anti-seize thread compound applicable for heavy pressure applications. It can be used in high temperature areas up to 870°C (1600°F).

• The adhesive is made of graphite foil and reinforced high-performance, heavy-duty, high-temperature, oil-base lubricant mixture
• Adhesive is inert, not in extremely cold or hot conditions harden or evaporated
• Temperature -29 degrees to 871 degrees
• The Commission MIL-PRF-907E testing
• The metal parts to prevent corrosion occurring in extreme environments such as high temperature, corrosion, abrasion or seizure phenomenon

LOCTITE® Silver Grade Anti-Seize Lubricant is a heavy-duty,
high-temperature anti-seize thread compound applicable for
heavy pressure applications. It can be used in high
temperature areas up to 870°C (1600°F).

TYPICAL APPLICATIONS

Silver Grade Anti-Seize Lubricant is used to lubricate and to
permit easy disassembly of assemblies exposed to high
temperatures and heavy contact pressures, such as boiler and
oven parts, jet engines, and industrial turbines.

DIRECTIONS FOR USE

1. For best results, ensure part surfaces are clean and free of
   debris.
2. Apply a light coating of product to parts requiring
   lubrication.
3. Assemble parts.
4. When part is assembled, wipe away any excess compound.

TYPICAL PERFORMANCE PROPERTIES

Static Coefficient of Friction

The following chart shows the static coefficient of friction
between controlled mating surfaces subjected to a compressive
stress that approximates the bearing stress acting on fastener
threads under load (60% of proof for a 3/8-16 Grade 5 steel).

Torque Tension

Tested on degreased 3/8x16 nuts & bolts in a SkidmoreWilhelm apparatus. Data reported are the k-factors calculated
from torque @ 5000 lbs tension.

CAUTION

Silver Grade Anti-Seize Lubricant is not a high-speed load
carrying lubricant and should not be used on ball or roller
bearings, or on parts where lubrication is critical.

Torque vs. Elevated Temperatures

The following chart shows break and prevail torque values for
plain steel 3/8-16 fasteners degreased, coated, pre-torqued to
30 ft-lbs, heat soaked at an elevated temperature for 24 hours,
cooled to room temperature and disassembled. (No signs of
galling or seizing were visible.)

Corrosion Resistance

Degreased steel specimens (3/8-16 Grade 5 bolts) were treated
with an even coating of Anti-seize and assembled into test
blocks of aluminum and carbon steel drilled and tapped with
3/8-16 holes. A small amount of Anti-seize was applied under
the bolt heads where high bearing stresses are present. The
assemblies were placed in a 95°F condensing humidity salt fog
chamber for 180 hours. After conditioning, the bolts were
removed and inspected visually for corrosion both in the threads
and under the bolt heads. There were no visible signs of
corrosion on any of the treated specimens.
The product was tested for corrosive effects on plain copper
strips. There was no sign of corrosion, discoloration, pitting or
etching upon completion of the test.

Wear Resistance

Extreme pressure testing with a Timken Lubricant Tester (ASTM
D2509) indicated Silver grade Anti-Seize Lubricant would resist
seizure, scoring and wear under adverse pressure conditions.
The test on Anti-seize consisted of a rotating spindle loaded and
held constant for a ten-minute interval. If no scoring of the test
block was noted, the load was increased and the test run.
The following chart shows the load at which failure occurred.
The load at which failure occurs is then reported to be the fail
load. The last acceptable load is considered to the OK load, or
non weld load

Torque, Galling and Seizing

Five (5) bolts, 3/4”-10 were pre-torqued to approximately 230 ft
lbs. (based on elongation) then conditioned for three six hour
cycles @ 1050°F with retorquing after each cycle. After heating,
the entire block assembly was exposed to a 20% salt solution
for seven days. Break torque didn’t exceed 250 ft lbs. There
was no seizing of any nuts during the test. There was no galling
evident on the threads of the nuts or studs.
