3M 7000000875 Epoxy Adhesive Part B 5 Gallon

Product Description

The 3M 7000000875 is the Base (Part B) component of the Scotch-Weld Epoxy Adhesive 460, a toughened, two-part structural epoxy adhesive designed for demanding bonding applications. Used as part of a B/A system at a 2:1 mix ratio, it delivers a 60-minute work life and reaches handling strength in approximately 4 hours. The adhesive provides good shear and peel strengths along with solid impact resistance and long-term durability. This 5-gallon container is suited for high-volume production or job-site applications where large quantities of structural adhesive are consumed regularly.

The 460 adhesive system is appropriate for industrial, manufacturing, and commercial construction environments where strong, reliable bonds are required across a range of substrate types. Typical applications include assembly bonding of metal fabrications, ceramic components, wood structures, and compatible plastic substrates. The extended work life makes it practical for larger bond areas or complex assemblies that require positioning time before cure. This product is Part B only — Part A (activator) must be ordered separately to complete the system.

Key Features

• 2:1 mix ratio for use with the corresponding Part A activator component
• 60-minute work life allows adequate assembly time for complex or large-area bonds
• Handling strength reached in approximately 4 hours after mixing
• Toughened epoxy formulation with good shear, peel, and impact strength
• Bonds to metals, ceramics, wood, and select plastics
• 5-gallon container supports high-volume or production-scale use

Compatibility

Designed for use as the Base (Part B) component in the Scotch-Weld Epoxy Adhesive 460 B/A two-part system. Compatible substrates include metals, ceramics, wood, and some plastics. Part A activator is required and must be sourced separately.

Installation Notes

Dispensing and mixing of two-part epoxy adhesives should be performed by personnel familiar with structural adhesive systems and applicable safety data sheet requirements. Ensure surfaces are clean, dry, and properly prepared before application. Do not use Part B alone — the system requires both Part A and Part B combined at the specified 2:1 ratio to cure properly. Follow all applicable workplace safety regulations and ventilation requirements when handling epoxy adhesives.
