For different use cases Würth CU 800 Würth AL 1100 Silicone Grease
Mechanical Fasteners ✔ Excellent under heavy loads ✔ Suitable with low galvanic risk ✘ Not designed for mechanical load
Salty or Coastal Environments ✘ Copper-based; can accelerate corrosion ✔ Best choice — high corrosion resistance ✔ Moisture barrier; good secondary protection
Electrical Conductivity (RF) ✔ High conductivity for grounding bonds ✘ Non-conductive ✘ Non-conductive (insulating compound)
Connector Weatherproofing ✘ Not recommended for electrical connectors ⚠ Acceptable for mechanical parts near connectors ✔✔ Excellent — waterproof, dielectric, non-melting
RVS (Stainless Steel) + Brass ⚠ Galvanic caution in coastal environments ✔ Safe, minimal galvanic effects ✔ Safe — chemically inert
General Outdoor Applications ✔ Effective for bolts & mechanical parts ✔✔ Excellent for almost all metal interfaces ✔ Provides long-term moisture sealing
RF Connectors (PL/SO-239, N, 7/16) ✘ Not suitable ✘ Not intended for electrical interfaces ✔✔ Ideal for weather sealing & dielectric isolation
Temperature Range –30 °C to +120 °C –40 °C to +1100 °C (short-term) –50 °C to +200 °C
Main Advantage High-pressure mechanical lubrication Ultimate corrosion protection for metals Best for waterproofing & insulating electrical parts
