Loctite LB 8504 Graphite Synthetic Anti-Seize Lubricant 454g
Available
Loctite LB 8504 is a dark grey, one-component, non-curing anti-seize thread lubricant formulated from synthetic graphite and petrolatum. It needs no mixing.
Henkel gives an operating range of -29 °C to +482 °C and states it shows good electrical conductivity in metal-to-metal joints. It also gives a torque coefficient for steel bolts and nuts.
Where this product is used
- Thread lubrication and anti-seize on threaded connections
- Steel bolts and nuts where a lubricated torque coefficient is needed (determine K for your own joint)
- Metal-to-metal joints where Henkel notes good electrical conductivity (no value given)

Selecting the right option
If your joint runs hotter than the range above, or you need a metallic grade, compare Loctite LB8151 Silver Grade Anti-Seize Aerosol 340g, Loctite 771 Nickel Anti-Seize Lubricant 500g and Loctite 51606 Heavy Duty Anti-Seize 510g.
Using it
Henkel gives a torque coefficient (nut factor) for this product and says to determine it experimentally for your own joint, using T = K x F x D.
The Henkel data sheet gives no step-by-step application directions.
Storage and handling
Store the unopened container in a dry location, optimally between 8 °C and 21 °C. Storage below 8 °C or above 28 °C can adversely affect the properties of the product.
Limits and safety
Not recommended for pure oxygen or oxygen-rich systems, or as a sealant for chlorine or other strong oxidising materials. Read the safety data sheet before use.
