Professional-grade heat-curable auto body joint sealer tape that conforms to irregular surfaces and provides excellent paint-receptive finish with superior weather resistance and durability.
3M™ Melt Sealing Tape 5232 is a conformable, non-PVC, structural, heat-curable auto body joint sealer tape designed specifically for sealing jointed panels in automotive applications. This white, high modulus-style tape features a thickness of 1.5 mm and provides excellent workability combined with professional-grade performance. The tape is linerless, repositionable, and tack-free, making it easily applicable to clean or E-coated surfaces for improved ease of use during installation.
Developed for optimal design freedom, 3M™ Melt Sealing Tape 5232 is applied as a tape and then heated to flow around joints and cure to a smooth, paint-receptive surface. The product seals jointed panels with reliable performance and uniform thickness, blending seamlessly to create a professional finish. It conforms to irregular surfaces including spot welds, weld flash, pillowing, and other surface imperfections, effectively covering these defects to enhance the overall appearance of the vehicle. After being painted, the tape's presence is completely unnoticeable, leaving vehicles looking flawless.
This innovative sealing solution doesn't require any special setup or equipment because it cures sufficiently in a conventional paint oven at temperatures between 15°C (59°F) minimum and 140°C (284°F) maximum. The tape provides very high final adhesion once cured, does not contain any plasticizer, and demonstrates excellent weather resistance and durability. It is ideal for hole sealing, molded part replacement, panel joint and edge seal bonding, and roof ditch sealing applications.
