• Two component liquid coating
• Intumescent
• 100 percent solids
• Solvent-free
• Lightweight

Properties

The fireproofing material has these qualities:

• Base: Epoxy two-component
• Colour: Matte grey
• Dry density: 1.4g/cm3 (87.4 .b/ft3)
• Solids: 100 percent
• VOC (volatile organic compound - supplied):
  • Directive 1999/13/EC, SED: max. 0.0 g/kg
  • EUR directive: 2004/42/IIA(i)(500) 0 g/l

Epoxy intumescent material notes
