OKS 1105 – Insulating Paste

OKS 1105 prevents the formation of electrically conductive layers and minimises the risk of flashovers and dielectric losses. The insulators and switchgear covered with the paste thus maintain a good insulation resistance.

Areas of application

  • Sealing lubrication for electrical or electronic equipment such as relays, plug-in connections, cable lugs and lamp sockets
  • Protection of insulators and switchgear in humid atmospheres, for example of junction boxes, screw terminals, overload cutouts at high-voltage pylons, connecting cables and terminal connections
  • Lubricant for plastic screw connections and other moving parts of metal, ceramic, plastic

Advantages and benefits

  • Excellent water repellent properties
  • Excellent surface wetting
  • Good adhesion on glass, porcelain and plastics
  • Stable consistency across a wide temperature range
  • Very good resistance to chemical and weather-based influences (e.g. ozone, UV radiation)
  • Neutral with regard to many materials
  • Small change in the dielectric properties across a wide temperature range

Technical specifications

  • Operating temperature: -40°C → +200°C
  • Electrical resistivity (25°C): > 1014Ωcm
  • Dielectric constant: 2.75


For optimum effectiveness, clean the point to be protected. Best way is to clean mechanically first and then with OKS 2610/OKS 2611 universal cleaner. Apply OKS 1105 evenly. Avoid excesses. Observe the plant manufacturer's instructions. If the protective layer is saturated with conductive particles, remove these and apply a new coating.
