Bluesil Paste 4 is a high-performance silicone paste based on polydimethylsiloxane oil with inert fillers. It has been specially developed for the protection and insulation of electrical and electronic components, even under extreme temperature conditions.

Key features:

  • Hydrophobic – provides excellent protection against moisture.
  • Chemically inert – resistant to aggressive substances, prevents corrosion and damage.
  • Excellent dielectric properties – ensures insulation and functionality of electrical systems.
  • Wide temperature range from –40°C to +200°C – reliable in extreme environmental conditions.
  • Complies with MIL and NATO standards – tested for military and NATO requirements.

Areas of application:

  • Aerospace – Protection of electrical switchgear in extreme environments.
  • Electric motors – sealing against moisture and pollutants.
  • Relays and cable connections – secure protection and reliable connections.
  • Battery terminals – corrosion protection for lasting performance.
  • Static lubrication – suitable for small systems to minimize friction and extend service life.

Processing instructions:

  • Apply to clean, dry surfaces. Degrease beforehand if necessary.
  • Apply with a brush, spatula, or paste gun.
  • For thin layers, Paste 4 can be diluted in highly volatile solvents (aliphatic or chlorinated).

Bluesil Paste 4 combines high efficiency in moisture protection, chemical inertness, and electrical insulation. Its wide temperature range and military specifications make it the ideal solution for demanding industrial applications, including aerospace, electrical engineering, power supply, and industrial maintenance.
