| NCB is formulated with
resin, inorganic halogen-free flame retardant, foaming agent,
carbonizing agent, and other auxiliary agents. When the coating
membrane is exposed to fire, the flame retardant ingredient
decomposes to build up foams on the surface which act as an
insulation layer and fend off heat and fire.
Characteristics: super-thin film, excellent fireproofing
effect, decorative finish, easy to apply, eco-friendly. Suitable
for fireproof coating of steel structures.
