3M 7000121361 Polyurethane Reactive Adhesive Black

Product Description

The 3M 7000121361 is a one-component, moisture-curing polyurethane reactive structural adhesive formulated for bonding wood and select plastics. Sold as part of the Scotch-Weld line, this black adhesive is 100% solids with no solvents to off-gas during cure. It is designed for sprayable or extrudable application, giving installers flexibility in how it is dispensed. The long open and set time makes it well suited for assemblies that require repositioning or clamping before the bond sets. Fabricators and assembly technicians working with wood, plastics, aluminum, or glass-to-plastic and glass-to-wood joints are the primary users of this product.

This adhesive is used in structural bonding applications where a durable, flexible joint is needed between dissimilar materials. Typical scenarios include furniture manufacturing, cabinet assembly, composite panel fabrication, and light industrial bonding of plastic components to wood or metal substrates. Its sprayable and extrudable nature supports both high-volume production lines using bulk dispensing equipment and smaller shop applications where controlled bead application is needed.

Key Features

• One-component formula requires no mixing prior to application
• Moisture-curing system activates on exposure to ambient humidity
• 100% solids construction with no solvent content
• Sprayable and extrudable for use with bulk dispensing equipment
• Long open and set time supports repositioning and clamping workflows
• Bonds wood, select plastics, aluminum, and glass to plastics or wood

Compatibility

Designed for structural bonding of wood, select plastics, aluminum, and glass-to-plastic or glass-to-wood material combinations as stated by the manufacturer.

Installation Notes

Application should be performed by fabricators or assembly technicians familiar with structural adhesive dispensing systems. Ensure substrate surfaces are clean, dry, and free of oils or loose material before applying. Cure rate depends on ambient temperature and relative humidity — adequate ventilation should be maintained during application and cure. Follow applicable workplace safety guidelines for adhesive handling, including appropriate PPE for skin and eye protection.
