Stiffening anti-fire mastic for wood and wooden products
Characteristics
Soft mastic, having declared anti-fire resistance for wood. Anti-fire single on-foaming substance for anti-fire gap protection and wooden material conversion. During the firing process by its heating dispersion starting from + 250 °C up to +300°C it creates on the protected material surface, strong anti-fire, heating isolation layer, which extends the resistance of wooden construction against fire influence and radiant fire, together with total amount of used substance predetermines this substance as an ideal and unique protection solution.
- Class of fire reaction B-s1, d0 classification according to STN 13501-1
- Anti-fire resistance EI 45 / minutes 1-6 mm gap
- Anti-fire resistance in system OSB REI 45 /1-8 mm gap
- Anti-fire systems sealing of wooden constructions and wood
- At temperatures over +200°C it is floaming
- It prevents fire dissemination and it resists fire
- After drying it can be coated by appropriate anti-fire coatings
