Product Benefits
  • Key ingredient for the transparent intumescent coating on various kinds of wood
  • Contains, in the combination with melamine-formaldehyde resins all necessary reaction partners for an intumescent reaction
  • Exolit® 855 is an aqueous solution and can hence not be used in solvent-based formulations.
  • Reacts at lower temperatures than conventional systems
  • Allows the combination of excellent fire-resistance and durability in high humid indoor areas with brilliant wood surfaces
  • Its unique transparency and clarity allows the formulation of clear varnishes on various wooden surfaces like MDF, chipboards, plywood and veneered wood
