3M 7010309750 Epoxy Adhesive 420 Black Part B 55 Gal

Product Description

The 3M 7010309750 is the Part B component of the Scotch-Weld Epoxy Adhesive 420 Black two-part toughened epoxy system. It is supplied in a 55-gallon open head drum and is paired with the corresponding Part A to form a structural adhesive used in industrial bonding applications. The system uses a 2:1 mix ratio, delivers approximately 20 minutes of work life after mixing, and reaches handling strength in approximately 2 hours. Installers and assembly technicians choose this adhesive for its balance of shear strength, peel resistance, and impact durability across a wide range of substrates.

This adhesive is suited for industrial manufacturing, fabrication, and assembly environments where a reliable structural bond is required. It bonds well to metals, ceramics, wood, and select plastics, making it applicable across HVAC equipment manufacturing, electrical enclosure assembly, and general metal fabrication. The 55-gallon drum format is intended for high-volume dispensing operations. This is the Base (Part B) component only and must be used alongside its corresponding Part A activator at the specified 2:1 ratio to achieve rated performance.
