Professional-grade heat-curable auto body joint sealer tape that conforms to irregular surfaces, creates smooth paint-receptive finishes, and provides excellent weather resistance with no special equipment required.
3M™ Melt Sealing Tape 5231 is a conformable, non-PVC, structural, heat-curable auto body joint sealer specifically engineered for sealing jointed panels in automotive applications. This professional-grade product is a white, high modulus-style tape with a thickness of 1.0 mm that combines excellent workability with superior performance characteristics. The tape is applied to clean or E-coated surfaces where it is then heated to flow around joints and cure to a smooth, paint-receptive surface that is ready for finishing.
Developed for optimal design freedom in vehicle manufacturing, 3M™ Melt Sealing Tape 5231 provides exceptional conformability to irregular surfaces, effectively covering imperfections including spot welds, weld flash, pillowing, and other surface irregularities that would typically require treatment in the sealer deck or paint shop. The linerless, repositionable, and tack-free design ensures easy application and superior workability during installation. Once cured, the tape achieves very high final adhesion and becomes virtually unnoticeable after painting, enhancing the overall appearance of the vehicle.
This innovative sealing solution requires no special setup or equipment, as it can be sufficiently cured in a conventional paint oven, making it ideal for integration into existing manufacturing processes. The product excels in weather resistance and durability while maintaining excellent paint appearance and uniform thickness. Being non-plasticizer, it meets stringent automotive standards and provides reliable long-term performance in demanding automotive environments.
