3M 7000121318 Two-part Epoxy Adhesive 400 Ml Clear

Product Description

The 3M 7000121318 is a rigid, two-part epoxy adhesive designed for structural bonding applications across a wide range of materials. Sold in a 400 mL cartridge, it uses a 1:1 mix ratio and delivers a 3 to 5 minute work life, with handling strength reached in approximately 20 minutes. Its low viscosity makes dispensing straightforward and consistent. Dispensing requires a compatible 3M Scotch-Weld EPX 400 mL applicator and mix nozzles, which are not included with the cartridge. This adhesive is suited for professional assembly, repair, and fabrication tasks where a fast-setting, rigid bond is required.

This epoxy adhesive bonds to metals, ceramics, wood, and many plastics, making it applicable across HVAC assembly, plumbing fixture repair, electrical enclosure fabrication, and general industrial maintenance. It is well suited for both shop use and field repair scenarios where a reliable structural bond must cure quickly without clamping equipment. Installers and service technicians working with mixed-material assemblies will find the short handling time useful for high-throughput workflows.

Key Features

• Rigid two-part epoxy formula with 1:1 mix ratio for consistent results
• 3 to 5 minute work life allows time for part positioning before cure begins
• Handling strength achieved in approximately 20 minutes
• Low viscosity for easy dispensing through EPX applicator systems
• Bonds to metals, ceramics, wood, and many plastics
• 400 mL cartridge format minimizes waste and simplifies metered dispensing

Compatibility

Requires a 3M Scotch-Weld EPX 400 mL applicator and compatible mix nozzles for dispensing; these accessories are not included. Designed for use with mixed-material assemblies involving metals, ceramics, wood, and many plastics.

Installation Notes

Surface preparation is critical for epoxy adhesive performance — clean all bonding surfaces to remove oil, dust, and oxidation before application. Do not mix or dispense without the appropriate EPX applicator and a fresh mix nozzle; purge the cartridge tip before each use session. Allow the bond to reach full handling strength before applying load. Follow applicable safety data sheet guidance for ventilation and personal protective equipment when working with epoxy systems.
