FB-2 Fireproof Coating Board
FB-2 Fireproof Coating Board is a kind of double-sided metal plate that the middle layer is an organi c/inorganic intumescent fire resistant layer with the silicone as a binder. By optimizing the formulation,combined with ceramization technology and fire safety technology, which makes product not only has excellent fire resistance performance, but also ensure that the system will be in a good stability after sealing when gets on fire, it also has features like: beautiful construction process, water impact resistance, high expansion, etc.
Simple working condition
Product advantages:
Convenient for construction;
Suitable for large and medium-sized hole sealing;
More than 2 hours fire resistance period;
Thermal expansion performance, smoke airtight;Stable system structure after expansion, water impact resistance;
Good appearance after construction, Remove the protective shield to avoid pollution;
Easy expansion;good bearing performance.
Installation Instructions:
Keep the hole clean ;
Measure the hole size;
Cut the fireproof plate into two halves, and cut according to the shape of penetration object;
Grind the sharp edges;
Fix the fireproof plate firmly;
Use FS-I( Intumescent fireproof sealan)to fill the cable cracks and the cracks around the fireproof plate.
