mcr Polylack W - intumescent paint system for fireproofing of steel building structures

European Technical Approval ETA-15/0801

Certificate of Constancy of Performance: 81230

mcr Polylack W, as per EN 13501-2:2007+A1:2009 standard, ensures achieving of the following resistance classes:

  • R15 to R60 - open sections - posts and beams
  • R15 to R45 - closed rounded and rectangular sections - posts
  • R15 to R45 - closed rectangular sections - beams

mcr Polylack W water-based intumescent paint system is used for fireproofing of steel structures in the building industry. It can be used both indoor, as well as outdoor at partial exposure, especially where high aesthetics of the protection is necessary.

Fire resistance of the system is ensured by proper selection of thickness of the protection in accordance to massiveness factor of the proofed element, designed fire resistance class, and critical temperature of steel.
