Product description
MOLYKOTE 4 25 kg is a silicone lubricating/sealing compound with excellent insulating properties, designed to protect connections against moisture and corrosion. Its semi-fluid consistency helps application in gaps and complex geometries, making it suitable for electrical connectors and rubber parts (seals, O-rings). MOLYKOTE 4 operates across a wide temperature range from -54°C to +200°C.
Advantages and unique features
- High dielectric strength and excellent insulating properties.
- Moisture resistance and water resistance for corrosion protection.
- Good adhesion to many dry materials (including metals, elastomers, polymers and ceramics).
- Low volatility/evaporation and good oxidative stability.
- Wide service temperature range: -54°C to +200°C.
- Semi-fluid consistency – easier lubrication and sealing of gaps.
Properties and applications
- Connectors and joints: lubricating and sealing cable connectors, battery terminals, rubber seals and O-rings.
- Moisture protection: moisture-resistant sealing in ignition systems, electrical connectors, disconnectors and industrial connectors.
- Transport & industry: where protection against moisture and corrosion is required.
- Application note: do not use on surfaces intended for painting or coating with other finishes.
