Railway carriage floor refurbishment through bonding and sealing

In the refurbishment of a railway carriage floor, linoleum bonding and perimeter sealing require adhesives and sealants compatible with different substrates and industry requirements.

Maintenance, bonding and sealing

During the repair of a railway carriage, the floor had to be refurbished by intervening on two distinct points: the bonding of the linoleum to the plywood wood panel and the sealing of the perimeter.

The point was not to choose a single material for the entire application, but to identify two solutions suitable for different functions. For bonding, KORAPUR® 672/80-TH350, a two-component polyurethane system, was selected. For perimeter sealing, Körapop™ 240, an SMP/MSP technology sealant, was chosen instead.

Bonding of
linoleum

Polyurethane technology supports adhesion between the linoleum covering and the plywood panel.

Perimeter
sealing

SMP/MSP technology allows for elastic sealing of the perimeter, with good adhesion on different substrates.

Railway requirements
EN 45545-2

EN 45545-2 documentation reports the compliance of the tested materials with fire behavior requirements, a relevant aspect for interior applications on railway vehicles.
