FB-1 Fireproof Coating Board
FB-1 fireproof Cable Coating Board is a kind of high inflation paints fire retardant coating on the surface of non-combustible board. It is mainly applied in sealing the electric cabinet, cable shaft and other large vertical holes.
Simple working condition
Product advantages:
Smoke non-toxic;
No halogen, sulfur and other toxic ingredients, Long-term performance for more than40 years；
No corrosion, Safe and environmentalprotection;
Efficient flame retardant;
Convenient for construction.
Installation Instructions:
Keep the hole clean and the surface dry;
Cut the FB-1 fireproof sealing plank into the shape that can match the holes and penetrations with tools；
Coat he FS- For FS-I on penetrations surface that is in contact with the sealing plank;
Brush the hole circum and coated board surface on every side with FS- F;
Pull the well-cut sealing plank into the holes, and keep it in a line with the substrate surface, banding with FS-F;
Paint surface of FB-1 with fireproof cable coating.
