Introduction
NCB (BCF-1) ultra-thin fireproof coating for steel structure
(thin coating metal coating)
First, product performance characteristics:
Baoquan brand NCB BCF-1 ultra-thin type of steel structure fire
retardant coating is my company and the Institute of chemical
technology and Fire Research Institute jointly developed the new
steel structure fire retardant products. The coating is thin,
strong adhesion, fast drying, convenient construction, refractory
and heat insulation and decoration integrated, the product
expansion type fireproof coating, fireproof performance prominent,
with thick and thin fire retardant coating for steel structure is
incomparable advantages. This product is non-toxic, resistant to
moisture, freeze-thaw resistance, corrosion resistance, aging
resistance and excellent physicochemical properties. In case of
fire when the temperature reaches the rapid expansion, the
formation of a thick layer of dense shaped bee fire insulation,
fire performance and fire resistant performance significantly, with
a long time.
Two, the scope of application:
The products under fire coating foaming ingredient that thermal
decomposition with dense and uniform heat generation, oxygen
barrier of intumescent char layer, prevent heat transfer, and the
decomposition of the endothermic reaction, slow temperature rise of
steel structure, play a role in protection of steel structures.
Widely used in all kinds of cable tray, public places of
entertainment, gymnasium, waiting room, airports, power plants,
exhibition hall, TV Tower, commercial buildings, large industrial
plants and other steel structure building fire retardant
engineering, NCB (BCF-1) ultrathin steel structure fire retardant
coating according to the fire protection design requirements
completely reaches the state of the fire rating standards.

Four, construction method:
1, before construction must steel structure, parts of the surface
dust, oil, grease, and other debris clean up do derusting
treatment, and coated with anti rust primer, and ensure and fire
retardant coating chemical reaction does not occur. After the rust
proof paint, the construction of fire retardant coating can be
carried out.
2, construction must be in the steel structure project acceptance,
steel structure is connected to the pipe fittings installed, the
roof waterproof project is completed, the interior decoration
before.
3, the construction environment temperature should be in 0 ~ 45
degrees Celsius, relative humidity should not be more than 85%, the
field of ventilation in a good environment. Before the construction
process and coating drying and curing, the construction must ensure
that the follow-up project is not damaged, and pay attention to the
protection of other facilities in the field.
4, can be sprayed (with a diameter of about 1mm paint spray gun for
spraying), brush coating, roll coating and other methods of sub sub
construction. The applied coating basic again after drying and then
spray brush again, the general interval of 5 10h, good ventilation,
high temperature, air humidity and dry environment between 3 - 5
hours until the desired thickness.
5, the use of fire retardant coatings, must be fully mixing, in
order to adapt to the construction of spray brush is appropriate.
The solvent type fireproof coating with special diluent, must not
be diluted with water or other liquids.
6, construction in case of rain should take shielding measures,
component surface condensation phenomenon, should not construction,
the need to extend the construction time interval.
7, just after the construction of the coating should be waterproof,
anti exposure, pollution and mechanical damage, if damaged, need
immediate repair.
Five, matters needing attention:
The product line of solvent based paint, the construction should be
carried out in a well ventilated conditions, paint storage,
transportation and construction coating not dry, the site should be
no open flames. Component condensation on the surface or air
temperature over 85% when should not construction, indoor
ultra-thin Department of fire retardant coatings for steel
structure coating, such as steel structure of an open environment
using the coating to protect, waterproof treatment on the surface
of the coating.
