Brake Systems in Trains

Brake systems play a vital role in trains, as they slow down and stop the train by applying a contact material to the rotating wheels or discs attached to the axles. The contact material used for braking is typically in the form of a pad or shoe.

Due to the high-intensity friction forces present during braking, brake systems require durable and strong bonding mechanisms.

Brake Bonding Adhesives for Railway

Adhesives can be used for the bonding of brake pads and shoes within trains. Unique advantages are experienced when using adhesives, as compared to mechanical bonding mechanisms, including lightweighting, corrosion resistance, temperature resistance, and easier application. These factors also lead to improved strength, cheaper costs, increased durability and reduced frequency of maintenance.

Specifically, adhesives that can successfully be used for brake bonding in rail vehicles must provide:

  • Excellent temperature resistance
  • Great adhesion to friction metals
  • Great adhesion to steel and aluminium

Huntsman Araldite provides two adhesives (and dip-coatings) that have effectively been used for bonding train brake shoes and pads.

Araldite 64-1 is a vinyl modified phenolic resin, designed especially for application as friction lining adhesive. It has effectively been used for brake bonding within railway applications for many years. It can be applied by roller coating or spraying.

Araldite 71 is another vinyl modified phenolic resin that can be used as an adhesive for brake shoes. It can be applied by extrusion or roller-coating.
