Molykote 4 Electrical Insulating Compound

NLGI Grade 2-3; translucent white; used primarily as a lubricant and moisture-proof seal for assembly of metal-on-polymer and metal-on-rubber combinations and sealed electrical connectors, disconnect junctions and terminals

Features & benefits

• High dielectric strength and excellent electrical insulating properties

Applications

A moisture-proof seal for transportation and industrial applications, including ignition systems, sealed electrical connectors, disconnect junctions and terminals where a semi-flowable consistency material is appropriate. Used as a seal and lubricant for cable connectors, battery terminals, rubber seals, switches, and rubber and plastic O-rings and as an assembly lubricant for various metal-on-plastic and metal-on-rubber combinations.

Composition

• Technology: Silicone
• Thickener: Silica

Available pack sizes

• 3.6 kg pail - 4 per carton
• 18.1 kg pail
• 199.5 kg drum

About this type of lubricant

Compounds are silicone-based, non-melting greases used less for friction than for sealing, insulating and protecting. Typical duty is dielectric insulation and moisture-sealing of electrical connections, lubrication and sealing of rubber and plastic parts, valve and O-ring assembly, and vacuum sealing.

How to choose

Compounds do not carry high mechanical loads — if the point is a loaded bearing or gear, a grease or paste is the right family. The silicone caution applies here too: a compound on a surface that will later be painted, bonded or printed will cause the coating to fail. On rubber and elastomer components, confirm compatibility with the specific elastomer — silicone compounds are excellent on most, and wrong on silicone rubber itself.

How to order

Specify the pack size and, where more than one grade shares a name, the exact grade on the RFQ. Indus Hydraulics is an authorised distributor and quotes MOLYKOTE® from Dubai stock where the grade is held; less common grades ship to order. Our engineers will confirm the grade against your application and operating conditions before you commit.
