NB Indoor thin fireproof paint for steel structure

 

Model: NB

 

1 Compositions

NB indoor thin steel structure fireproof paintis consisted of the organic composite resin, filler, etc, and selected from the latest flame retardant agent, foaming, carbon, catalyst processed new fireproof paint.

 

2  Applications

Suitable for stadium, exhibition hall, power stations, airports, the station waiting room and industrial plant bare bearing steel structure of the beam and column and steel pipe, It provides not only fire protection, thermal insulation but also decoration effect.

 

3  Fireproof theory

The paint sprayed on the surface of steel structure, generally as decoration purpose, if encountered with fire,the paint can expand, thicken, charring to form a nonflammable spongy carbonaceous layer, so as to improve the steel structure of the refractory limit to 2.5 hours,to win the fire extinguishing time, effectively protect the steel structural building from fire damage.

 

4  Performance and characteristics

1 Excellent fireproof performance, fire resistance time is long, can withstand the test of fire

2 High strength, application, and no need to reinforced barbed wire for fire protection coating

3 Excellent inweathering performance, prolonged notyellowed

 

5  Technology index

Item	Standard	Test Result
State in container	Smooth liuid after stirring,no block	Smooth liuid after stirring,no block
Surface dry	<12h	8h
Initial drying crack resistance	1~3 crack allowed,width≤0.5mm	No crack
Bond strength	≥0.15Mpa	1.12MPa
Water resistance	≥24h No layer, foaming, flake	No layer, foaming, flake after 24h
Resistance to cold and hot cycling	≥15 times,no crack,flake,foaming	No crack, flake, foaming afer 15 times
Fire resistance	When thickness≤5+/-0.5mm,fire proof must be no less than 1h.	Measured coating thickness of 4.7mm, refractory experiments to 160min, fire resistance equal 2.7h.

 

6  Application method

(1) Due to that fireproof paint is generallyrough, it’s better to adopt gravity type gunwith automatic pressure regulating 0.4-0.6 Mpa; Partial repair and small area by brush, spray or roller is recommended, combine one or more methods for convenient painting. Spray gun nozzle among 1-3 mm used to spray undercoats, can also be used to spray surface coating. Increase painting times if by hand.

(2) Every time the spraying thickness should be no bigger than 0.5mm,In sunny weather conditions, spraying interval is 8 hours to let the layer dry. Manual painting of each layer is thin, so calculate painting layers according to total thickness.

(3) According to the designed requirement on fire-proof time, confirm the total thickness, the theory consumption is: 1-1.5 kg/sqm/mm.

(4) It is suggested to apply extra 1-2 layers of acrylic or polyurethane anti-corrosion paint to ensure smooth and perfect decoration effect.

 

7  Dosage:

 

Fire-Proof time	Required Thickness	Total Consumption	Thickness of Each Layer
1 hour	2 mm	2~2.5 kg/m2	0.5 mm
2 hours	4 mm	4~4.5 kg/m2	0.5 mm
2.5 hours	5 mm	4.5~5.5 kg/m2	0.5 mm

 

 

8  Storage

Should be stored under indoor temperature -5 °C -40 °C , dry and ventilated environment. The paint is a solvent-based,keep it away from fire for safety.
