Key Features

• 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.

Applications

• 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.

Benefits

• 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.
