Loctite Silver Grade Anti-Seize 76764 453.6gLoctite® Silver Grade Anti-Seize. Heavy duty, temperature resistant, pertroleum-based lubricant compound fortified with graphite and metallic flake. Inert, will not evaporate or harden in extreme cold or heat. For use in assemblies to 1600°F (871°C). Guards against rust and corrosion caused by chemicals and weathering. Eliminates galling and cold welding of threaded parts including aluminum and stainless steel. Lubricates threads, gears, chains, cables, sprockets, levers, pivots, rollers, conveyors, oven doors and hinges.

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).

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.

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.

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).
Temperature                             Coefficient of Friction
-65°F (-54°C)                                          0.043
68°F (20°C)                                            0.077
1400°F (870°C)                                       0.164

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

Lubricity “k” Factor                                0.18

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

Load Type                                           Pressured Applied

OK load, lbs                                           47
Fail Load, lbs                                          52
Scar width at failure, mm                          0.83
Stress value at failure,N/mm2 (psi)            65 (9458)

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.
