3M Automotive High-Bond Attachment Tape 06391 is a thicker-profile, black, double-coated acrylic foam tape. It is specifically developed for attaching automotive exterior and interior trim components. This tape offers enhanced gap-filling properties. It also utilizes 3M’s advanced adhesive system for robust bonding. This ensures long-term durability and aesthetic integrity for critical automotive assemblies.
General Information of 3M Automotive High-Bond Attachment Tape 06391
The 3M Automotive High-Bond Attachment Tape 06391 features a unique black acrylic polymer foam core. Its thicker build provides superior stress relaxation. Consequently, it maintains aesthetic bond-lines even under high application loads. The tape incorporates a dual acrylic adhesive system, specifically JL-2 and VR-1 Acrylic Adhesives. This combination ensures excellent adhesion across various automotive paint systems. These include traditional, low surface energy, and highly durable scratch-resistant finishes. Furthermore, its robust construction delivers outstanding resilience against impact forces, particularly in cold weather environments. The black color ensures a discrete and professional finish, blending seamlessly with automotive components. This specialized formulation, known as 3M Automotive High-Bond Attachment Tape 06391, addresses the demanding requirements of modern automotive manufacturing. It provides a reliable and high-performance attachment solution.
Key Features & Technical Benefits
- Exceptional Adhesion Performance: Bonds firmly to a wide range of automotive paint systems. This includes traditional, low surface energy, and advanced scratch- and mar-resistant finishes. This versatility ensures reliable attachment across diverse vehicle models and component types.
- Advanced Thicker Foam Core: Features a unique foam core designed for superior stress relaxation. This critical property prevents bond-line read-through and maintains aesthetic integrity. It effectively dissipates stress from differential thermal expansion and contraction, ensuring long-term performance.
- Outstanding Cold Weather Resilience: Demonstrates remarkable resistance to impact forces in cold environments. This ensures the integrity of attached components, preventing detachment or damage during extreme temperature fluctuations.
- Discrete Black Construction: The tape’s black color ensures a professional and virtually invisible bond-line. This enhances the overall aesthetic appeal of the vehicle. It eliminates concerns about visible adhesive lines, maintaining a clean finish.
- Enhanced Gap-Filling Capability: Its thicker profile excels at filling larger gaps between components. This creates a more uniform and secure bond. It also accommodates minor surface irregularities, improving overall fit and finish.
Typical Industrial Applications
This formulation is engineered for the following applications:
- Attaching body side moldings, claddings, and wide body side moldings, requiring significant gap-filling.
- Mounting rugged exterior components such as wheel flares, bumper trim, and rocker panel moldings.
- Attachment of roof ditch moldings and luggage rack slats, ensuring secure and durable placement.
- Securing emblems, door edge moldings, interior trim panels, and A & B pillar trim for a professional finish.
