3M Scotch-weld 7000000816 Epoxy Structural Adhesive 1 Gal

Product Description

The 3M SCOTCH-WELD 7000000816 is a two-component epoxy structural adhesive supplied in a 1-gallon can. It delivers high-strength bonding performance with a 90-minute working time, giving technicians and fabricators adequate open time for complex assemblies and fixture setups. The cured adhesive produces a gray bond line and achieves a shear strength of 3,200 psi, making it suitable for demanding structural bonding applications across metal, composite, and rigid substrate materials. At 21.5 pounds per container, the 1-gallon can is sized for production-volume work where single-cartridge formats are not practical.

This adhesive is used in structural bonding applications where a long working time is required to align and clamp large or multiple components before cure begins. Typical use cases include metal fabrication, composite panel bonding, and industrial assembly operations. Maintenance and repair technicians working on equipment frames, enclosures, and structural joints also use this product where mechanical fasteners alone are insufficient or impractical. The 90-minute working time makes it well-suited for shop environments rather than field service where rapid cure is preferred.

Key Features

• 90-minute working time allows extended open time for complex or multi-part assemblies
• 3,200 psi shear strength provides structural-grade bond performance
• Gray color allows visual inspection of bond line coverage
• 1-gallon can format suits production and high-volume bonding work
• Epoxy chemistry bonds metal, composites, and rigid substrates

Compatibility

Designed for structural bonding applications across rigid substrates including metals and composites. Consult the product technical data sheet for surface preparation requirements and substrate-specific bond performance data.

Installation Notes

Application should be performed by trained personnel familiar with two-component epoxy handling and surface preparation procedures. Substrates must be clean, dry, and free of oils, oxides, and contaminants before adhesive is applied. Observe pot life limits and ensure components are fixtured before the 90-minute working time expires. Refer to the manufacturer technical data sheet for cure schedule, mixing ratio, and ventilation requirements prior to use.
