Protect Your Electrical Connections with Compound R391

Compound R391 Electrical Weatherproof 2x250g is a premium plastic sealing compound designed to safeguard electrical connections from moisture, corrosive vapours, and environmental wear. Whether you're working in industrial atmospheres or simply seeking reliable weatherproofing for electrical components, this non-hardening, putty-like compound is your go-to solution.

Why Choose Compound R391?

  • Weatherproof and Durable: The plastic compound creates a strong seal that prevents moisture ingress, protecting your electrical connections from leaks, short circuits, and corrosion, even in harsh conditions.

  • Non-Hardening Formula: Unlike traditional sealants, Compound R391 remains flexible, allowing you to mould it easily around terminals, connectors, and intricate surfaces. It can be removed and reapplied during maintenance without losing its integrity.

  • Versatile Use: Perfect for a range of applications, including sealing cable entries, irregular openings, screw threads, and electrical enclosures. It’s ideal for non-electrical uses, offering reliable moisture protection in any setting.

  • High Adhesion: The compound adheres effectively to materials like metal, wood, plastic, rubber, and PVC, ensuring a long-lasting seal that resists vibration and environmental wear.

  • Resistant to Harsh Conditions: Compound R391 is highly resistant to water permeation, acids, and alkalis. It retains its properties even when exposed to sunlight or fluctuating temperatures, from -20°C to +80°C.
