Application

  • Used as reduction of ignitability of softwood and hardwood ≥10 mm thickness and other timber derivatives, e.g. plywood, chipboard, fibre insulation board, hardboard and also on veneering ≥13 mm thickness.
  • Insulates against heat, checks fire, prevents propagation of fire and spread of flame and diminishes flue gas temperatures.
  • It should not be used in areas of high humidity, heat sources or on surfaces where significant physical impact is likely such as floors, stairs, etc.

Description

A one-pack, ecological and efficient water-based, transparent fire protection coating which forms a carbon char under the effect of heat.

It is thoroughly tested to provide spread-of-flame protection and delays the inflammation of interior natural wood and wood derivates.
