FC-1 Fire plaster Fire plaster
FC-1fireproof plaster is a kind of inorganic sealing material that is mainly applied to seal the large and medium-sized penetrated hole. It is mainly applied to the fireproof sealing of cable tray, cable trench and cable tunnel.
Simple working condition
Product advantages:
Smoke non-toxic;
No halogen, sulfur and other toxic ingredients, Long-term performance for more than 60 years;
Watertight,smoke airtight;
Resistant to radiation;
It will not shrink when solidification or on fire;
High anti-explosion performance;
Good insulativity;
No corrosion, safe and environmental protection.
Installation Instructions:
Clean the opening.
Place 1kg of FC-1 dry powder into a container, then add 0.3kg to 0.5kg of water, and stir thoroughly and evenly until a mortar-like consistency is formed—no lumps or dry particles shall remain.
Set up formwork and fill the plaster into the sealing area.
Identification labels may be installed for identification during later.
