Phenolic Systems for Interior Rail Composites

For lightweight, highly fire safe, cost efficient interior composite parts such as train fronts, window surrounds, roofs, flooring, side panels, stand backs, luggage racks, driver's desks, toilet modules and heat shields, we offer CELLOBOND™ and EPONOL™ phenolic resin systems.

These systems exhibit excellent mechanical properties and can meet stringent Rail Fire Safety standards EN 45545 category HL3 and BS 6853 category 1A.

CELLOBOND phenolic resin systems:

  • Engineered 40 - 50% lighter than aluminum
  • For RTM/VARTM—filler free, low viscosity system can infuse even fine weave cloths
  • For hand lamination—ultra-low emitting systems, variable cure rates

EPONOL phenolic resin systems:

  • For prepreg with carbon or glass fiber
  • Excellent fiber wetting
  • Long shelf life
  • High impact strength
