Panel Bonding Adhesive - 3M Automotive

Part #: 8115

Two-Part Epoxy Formula: Delivers high-performance structural bonding for various automotive substrates.
Corrosion Inhibiting Properties: Formulated with corrosion inhibitors to help prevent rust and enhance the longevity of repairs, offering better protection than traditional welding in many applications.
Controlled Bond Line Thickness: Features integrated glass beads that ensure an optimal and consistent bond line, preventing over-clamping and promoting uniform adhesive application.
Versatile Substrate Adhesion: Effectively bonds a wide range of materials including steel, aluminum, SMC (Sheet Molded Composite), and FRP (Fiber Reinforced Plastic), accommodating diverse repair needs without requiring a primer on many surfaces.
Extended Work Time with Heat Acceleration: Provides a generous working time of up to 90 minutes for accurate panel alignment and repositioning, with the option to accelerate curing using heat to optimize shop efficiency.
Weld-Bonding Capability: Can be spot welded through or used in conjunction with rivets, providing flexible repair options and reinforcement.
Sandable and Paintable: Allows for seamless finishing and integration with existing automotive paints after curing.

Designed for bonding and sealing outer body panels in automotive collision repair.
Ideal for replacing quarter panels, roof panels, door skins, box sides, van sides, and utility vehicle panels.
Suitable for specific bumper cover repairs under certain conditions.
Effectively bonds dissimilar materials including cold rolled steel, galvanized steel, aluminum, SMC, and FRP.
Important Note: This adhesive is not intended for use on structural components such as pillars, sills, core supports, or frame members; such components typically require welding or other OEM-specified repair methods.

Enhances Repair Durability: Provides a strong, long-lasting bond that actively resists corrosion, contributing to the overall integrity and lifespan of the repair.
Streamlines Repair Processes: Eliminates the need for welding or riveting in many exterior panel applications, which reduces heat distortion, minimizes grinding, and saves time on preparation and finishing.
Ensures Professional Finish: Facilitates precise panel alignment and bond line control, allowing for a smooth, sandable, and paintable surface that blends seamlessly with the vehicle's original finish.
Reduces Labor and Material Costs: Minimizes the need to remove adjacent components often required for welding, and its excellent shelf life reduces product waste.
Increases Repair Versatility: Bonds a wide range of common automotive materials, making it a flexible and efficient solution for various non-structural body panel repairs.
