Rail & Transit Infrastructure

Rail and mass transit applications impose a distinct combination of fire safety, durability, and acoustic performance requirements that general construction or automotive sealants do not address. Rolling stock interiors must comply with fire, smoke, and toxicity standards — EN 45545-2 in Europe, NFPA 130 in North America, and equivalent regional standards — that govern every material in the vehicle interior. Station platform infrastructure requires sealants that withstand pedestrian traffic, weathering, and continuous thermal cycling. Trackside applications such as rail pad bonding and sound barrier installation demand fatigue resistance under millions of loading cycles.

MS polymer sealants can be formulated to meet fire safety classifications through halogen-free, non-toxic flame-retardant filler systems — an approach that is inherently compatible with the low-smoke, low-toxicity requirements of enclosed transit environments. The isocyanate-free chemistry eliminates worker exposure concerns during vehicle fit-out operations, and the solvent-free, low-odor formulation enables application in enclosed rolling stock interiors without forced ventilation. Primerless adhesion to the mix of metal, composite, and engineering plastic substrates found in modern transit vehicles simplifies manufacturing and maintenance operations.

Silantek’s rail product range includes interior panel and trim sealants with EN 45545-2 fire classification pathways, platform edge and tactile paving adhesives, rail pad bonding adhesives for vibration isolation, and structural adhesives for sound barrier panel installation.
