Cafco MANDOLITE® CP2 produces a monolithic coating able to withstand thermal shocks experienced in a cellulosic fire. Concrete structures in particular, can be protected from explosive spalling when coated with Cafco MANDOLITE® CP2.

Fire resistance

Steel structures protected with Cafco MANDOLITE® CP2 have undergone fire resistance tests up to 240 minutes in approved independent laboratories to recognised standards throughout the world, including:

  • Australia (AS 1530: Part 4: 2005)
  • Germany (DIN 4102: 1977-2009)
  • International Standard ISO 834: 2002
  • UK (BS 476: Parts 20 and 21: 1987)
  • USA (ASTM E119: 1998 and UL 263)

Cafco MANDOLITE® CP2 protected structures have been successfully tested under BS 476: Part 21: 1987 to failure temperatures of up to 800ºC. This allows the specifier the freedom to adopt a fire engineering approach to fire resistance in accordance with BS 5950: Part 3 and 8: 1990, as well as the relevant Eurocodes. Fire resistance test results relate solely to the constructions tested and test conditions imposed.
