3M Channel Bonding & Sidelite Adhesive 08641 — 47.3 mL Dual‑Cartridge Black Epoxy, Fast‑Cure Automotive Glass Bond

3M Channel Bonding and Sidelite Adhesive 08641 is a two-part black epoxy cartridge designed to securely bond automotive glass to metal or plastic for both fixed and movable glazing applications.

This high-performance adhesive from 3M comes in a 47.3 mL dual-component cartridge formulated to cure quickly while retaining enough flexibility for long-lasting glass attachment. Engineered for automotive glazing work, it blends strong shear and peel resistance with a black finish that preserves original equipment appearance. Intended for professional and industrial use, the product helps technicians reassemble sidelites, vents, and other vehicle glass components where a durable, weather-resistant bond is required.

How does this adhesive perform on vehicle glass installations?

The 08641 epoxy offers robust adhesion to nonporous surfaces such as glass, metal, and certain plastics, forming a resilient joint that resists vibration and environmental exposure. It cures rapidly compared with many structural adhesives, reducing vehicle downtime while achieving a dependable bond.

• Two-part chemistry for a high-strength, crosslinked bond
• Formulated to work on glass-to-metal and glass-to-plastic interfaces
• Fast cure rate suited to shop workflows
• Black color to match OEM sidelites and channels

Will this adhesive withstand movement and road vibration?

Yes — the cured epoxy balances stiffness and flexibility to tolerate the small deflections that occur in sidelites and movable glazing. That combination helps preserve the bond under repeated stress while maintaining the seal and alignment of the glass.

• Engineered flexibility for dynamic applications
• High shear and peel resistance for durability
• Resists vibration and thermal cycling found in vehicles

What are the practical application and curing considerations?

3M supplies the 08641 in a premeasured two-component cartridge that is dispensed and mixed through an appropriate static mixer and applicator gun. Surface prep, correct mixing, and following the recommended cure window are essential for optimal bond strength and final appearance.

• Use a compatible dual-cartridge gun and static mixer for dispensing
• Prepare glass and substrates by cleaning and priming per shop procedures
• Allow recommended cure time before road use to ensure full performance

Is this product suitable for DIY and retail sale?

This cartridge is intended for industrial and occupational settings and is supplied for professional use. It is not intended for consumer retail sale or unsupervised home use; trained technicians should handle dispensing, safety, and curing tasks.

• For industrial/occupational use only
• Requires professional-grade dispensing equipment and safety measures
• Follow 3M safety data sheet and application instructions closely
