3M 7100082565 Epoxy Potting Compound 400 Ml

Product Description

The 3M 7100082565 is a rigid, two-part epoxy potting compound in a 400 mL cartridge, formulated for potting and bonding electronic and electrical components. It features a 1:1 mix ratio, a 70-minute work life, and reaches handling strength in approximately 3 hours. The compound is low viscosity for easy dispensing, non-corrosive to copper, non-exotherming, and high flow. Licensed electricians, electronics technicians, and field service professionals working on control boards, sensors, and enclosure assemblies are the primary installers of this compound.

This potting compound is used in residential and commercial applications where electronic and electrical components require protection from moisture, vibration, and environmental exposure. Its low viscosity makes it well suited for flowing around tight component layouts on circuit boards and inside electrical enclosures. The non-exotherming formulation reduces heat-related stress on sensitive components during cure.

Key Features

• Rigid two-part epoxy formulation with 1:1 mix ratio for consistent dispensing
• 70-minute work life allows sufficient time for complex potting tasks
• Handling strength reached in approximately 3 hours
• Low viscosity and high flow for easy penetration around components
• Non-corrosive to copper and non-exotherming for safe use on sensitive electronics
• 400 mL cartridge format — requires Scotch-Weld EPX 400 mL applicator and mix nozzles (not included)

Compatibility

Designed for potting and bonding electronic and electrical components. Requires a Scotch-Weld EPX 400 mL applicator and compatible mix nozzles, which are sold separately and not included with this cartridge.

Installation Notes

Apply using a compatible EPX 400 mL dual-cartridge applicator with the appropriate static mix nozzle attached. Before dispensing, ensure the substrate surfaces are clean, dry, and free of oils or contaminants. Allow full cure before energizing any potted components or reassembling enclosures. Follow applicable electrical codes and the compound manufacturer's safety data sheet when working in confined or poorly ventilated spaces.
