3M 7100010680 Epoxy Adhesive 400 Ml Two-part

Product Description

The 3M 7100010680 is a toughened, non-sag, two-part epoxy adhesive sold under the Scotch-Weld DP420NS designation in a 400 mL Duo-Pak cartridge. It uses a 2:1 mix ratio and delivers a 20-minute working life after mixing, with handling strength reached in approximately 2 hours. The formulation provides good shear and peel strength along with strong impact resistance and long-term durability. It is intended for structural and semi-structural bonding applications handled by technicians and tradespeople working with mixed-substrate assemblies.

This adhesive bonds to metals, ceramics, wood, and select plastics, making it suitable for a range of fabrication, repair, and assembly scenarios. The non-sag characteristic allows application on vertical or overhead surfaces without slumping before cure. The 400 mL Duo-Pak cartridge is designed for use with a 3M Scotch-Weld EPX 400 mL applicator gun, which meters and mixes the two components at the correct ratio through a static mix nozzle.

Key Features

• Toughened two-part epoxy with non-sag consistency for vertical and overhead application
• 2:1 mix ratio formulation metered automatically through a Duo-Pak cartridge
• 20-minute working life provides adequate open time for part positioning and adjustment
• Handling strength achieved in approximately 2 hours after mixing
• Bonds to metals, ceramics, wood, and many plastics
• Good shear strength, peel strength, impact resistance, and long-term durability

Compatibility

Designed for use with the 3M Scotch-Weld EPX 400 mL applicator and compatible static mix nozzles sized for 400 mL 2:1 Duo-Pak cartridges.

Installation Notes

Surface preparation is critical to bond performance — clean, degrease, and where applicable abrade substrate surfaces before applying adhesive. Dispense a small amount of mixed material and discard before bonding to ensure the two components are fully combining through the static mix nozzle. Do not attempt to use the cartridge without an appropriate EPX applicator gun, as improper mixing will degrade bond strength. Curing times vary with ambient temperature; lower temperatures extend both working life and time to handling strength.
