Copaslip High-temperature Anti-seize Compound


COPASLIP is a high-performance compound specifically formulated to protect fasteners from seizure-induced by extremes of temperature, pressure, and corrosion. The semi-synthetic base fluid is reinforced with anti-oxidants, corrosion inhibitors, and ultra-pure copper particles to provide outstanding protection to threads and components.
COPASLIP minimizes variations in frictional interference between threads, allowing accurate and consistent assembly. It also prevents galling and seizure during assembly and dismantling – even after long periods of exposure to high temperatures, corrosive environments, or high pressure.


  • Ensures consistent friction between threads
  • Protects against galling and seizure
  • Protects against rust and corrosion
  • Eases assembly of tight-tolerance components
  • Withstands extreme temperature up to +1100°C

When a compound is applied to a threaded fastener that will be tightened to a specific torque setting, the torque setting will require adjustment to allow for the lubricating effect of the compound. Failure to do so can result in incorrect tension in the fastener.
Correct torque settings can be calculated using the tables and charts below and the standard thread equation:
T = Torque (N.m), D = Diameter (m), P = Clamping force (N), K = Nut factor

Material K Nut factor
8.8 Steel self-coloured 0.14
8.8 Steel BZP 0.10
8.8 Steel hot-dip galvanised 0.14
A2 Stainless steel 0.13
Brass 0.12
