View pdf data-sheet

Type Copper paste for components subjected to high temperatures, high pressures and corrosive influences.
Typical applications Areas that must be protected against water, steam and corrosion e.g. brake mechanisms, flange seals, exhauster bolts.
Properties
  • Wide service temperature range
  • Good pressure resistance
  • No drop point, hence no melting or running-out
  • Low evaporation tendency, hence long lubrication effect
  • Very adhesive and resistant against water wash-out
  • 400 h corrosion protection
