CRC SL35901 Anti-Seize Copper Paste 8 oz Brush-Top Can

SKU CH-WPN8-28EWC

Copper-based anti-seize paste in an 8 oz brush-top can protects metal threads from seizing and corrosion between -95 °F and 2,000 °F

  • Withstands extreme heat up to 2000 degrees Fahrenheit
  • Remains effective in severe cold down to minus 95 degrees Fahrenheit
  • Copper-based formula prevents seizing and galling on threaded parts
  • Brush-top can allows precise application without separate tools
  • Non-flammable composition adds safety during storage and use

Copper Anti-Seize Paste 8 oz

CRC SL35901 is a copper-based anti-seize compound supplied in an 8 oz brush-top can. It is designed to prevent seizing, galling and corrosion on threaded fasteners and mating surfaces. The paste remains effective from -95 Degrees F up to 2,000 Degrees F. The brush-top applicator allows controlled, mess-free application directly onto threads.

Suited for general maintenance and assembly

Mechanics and technicians who need a high-temperature lubricant for bolts, studs, flanges and spark-plug threads will find this product fits routine workshop tasks. The copper formulation conducts heat and resists wash-out in harsh environments. Buyers who require a nickel-grade or ceramic compound for extreme chemical exposure or food-grade approval should look at alternative formulations not covered by this copper paste.

Temperature range and coverage headroom

The compound handles continuous exposure up to 2,000 Degrees F and stays pliable down to -95 Degrees F, covering most automotive, industrial and exhaust-system needs. An 8 oz can provides enough material for dozens of typical fastener applications. Very large flange assemblies or high-volume production lines may consume a can quickly, so plan quantities accordingly.

Questions about this item

What temperature range must the bolts or fittings I treat stay within for this copper paste to remain effective?

The paste is rated from -95 degrees F up to 2,000 degrees F, so it stays effective across that full range.

Will this copper-based anti-seize react with the stainless steel or aluminium hardware I already have on the vehicle?

Copper-based formulas are generally compatible with stainless steel and aluminium threads, preventing galling without causing galvanic issues.

How can I confirm the paste is still protecting threads after I have assembled the joint?

When you later disassemble the joint, the threads should turn freely with no sign of rust, carbon fusion or galling damage.
