3M™ Anti-Corrosion Protection Tape
In the railway sector, where the availability of carriages is essential to maintaining competitiveness, especially in passenger services, 3M adhesive solutions are revolutionising the way maintenance challenges are addressed. Imagine significantly reducing the costs associated with complex repairs, minimising vehicle downtime and improving operational safety without sacrificing durability. These specialised tapes, such as 425 aluminium, 5425 for noise protection, 8590 anti-corrosive zinc and 7070UV for industrial surfaces, enable the integration of smart strategies from the design phase to rapid field interventions. By prioritising reversible and resistant connections, not only is the service life of components extended, but compliance with strict regulations, such as those related to fire and toxicity, is also facilitated.
Applications for the Railway Sector
Incorporating these adhesive tapes at the initial stage of carriage design allows for the creation of structures that facilitate future interventions, reducing stress on materials and optimising the entire life cycle.
3M™ Aluminium Tape 425
- The 425 aluminium tape is integrated into air conditioning and duct sealing systems, acting as a thermal barrier that reflects heat and prevents air leaks, which not only improves passenger comfort on long journeys but also prevents condensation damage in variable climates. This eliminates the need for heavy mechanical fasteners, such as screws, which could loosen with constant vibrations.
- Seals joints in refurbished HVAC systems, protecting against water infiltration that could cause mould or electrical faults, and its resistance to high temperatures ensures consistent performance in environments with extreme thermal variations.
Scotch™ UHMW Polyethylene Tape 5425
- 5425 tape is applied to sliding guides and door or seat seals, where its low friction minimises annoying noises and wear due to friction, extending the durability of components exposed to intensive use.
- Ideal for installing new coatings on high-speed carriages where noise is a critical factor.
3M™ Industrial Protective Film 7070UV
- 7070UV tape protects interior surfaces such as control panels and handrails from damage caused by impact or exposure to sunlight, maintaining a professional appearance and complying with safety standards such as EN 45545-2.
- Thanks to its transparency and UV resistance, it is used in decorative panels or touch surfaces, preventing discolouration and scratches from frequent cleaning.
3M™ Anti-corrosion Protection Tape 8590
- 8590 tape protects metal joints in chassis and external structures against atmospheric corrosion, especially on lines that cross humid or coastal areas, acting as a sacrificial layer that preserves the base metal without requiring complex welding.
- Galvanic protection that stops the advance of rust.
In summary, although each one excels in a specific area (thermal/reflective, anti-friction, galvanic anti-corrosion or anti-scratch/UV), their common denominator is that they are tools for durable protection and efficient maintenance in industries where downtime is costly and reliability is essential.
