LANGCHAO FIRE
Fire Retardant Paint
WHO WE ARE
SiO?, aerogel created by American scientist Kistler in 1931, because of its low thermal conductivity (0.013
W/(m?K)), large specific surface area (800~1000m2), large porosity (80%~99.8%) and extremely small
apparent density (3.55kg/m'), making it widely used in aerospace, aviation, military and other fields. With the
deepening of research, the preparation and processing technology of SiO? aerogel has been optimized, and
the performance has been greatly improved to a certain extent, and it has become more and more favored in
the civil field. Luoyang Langchao Fire Technology Co., Ltd. cooperated with the joint research units of China
and Germany to develop an aerogel fire retardant paint with superior performance, the foaming rate is about
37% higher than that of ordinary fire retardant paint, the fire rate time is nearly 33% higher than that of
ordinary fireproof coatings, and the flame-retardant carbon layer structure is dense, the pore size is uniform,
and the physical and chemical properties fully comply with the provisions of GB14907-2018 standard. LCF
successfully applied aerogel to fire retardant paint for the first time, as a high-end new product can enhance
the competitiveness of enterprises in the fire protection industry, and can be comparable to the impact of
well-known foreign fireproof coatings.

Datasheet
The aerogel fireproof coating series products produced by LCF, cementitous coating for steel
structure is mainly composed of inorganic thermal insulation material with aerogel technical.
General building for steel structure, also can be used in petro & oil plant, chemical engineering, garage,
oil drilling platform and other buildings prone to high temperature fire caused by hydrocarbons.
Environmental protection coating, does not react with any anti-corrosion primer, does not corrode
steel, can be coated in a large area, and does not produce smoke in case of fire. The addition of
aerogel material has excellent fire and heat insulation performance, and can withstand flame high
temperature for a long time. Strong adhesion, good weather resistance, not afraid of wind, rain, sun,
no skin, no peeling, no aging, long life. Does not contain asbestos and organic solvents and other
substances, does not produce irritating gases, harmless to the human body Easy to construct, can be
sprayed directly, short drying time light coating, strong adhesion, long life. Excellent fire resistance.
The substrate shall be clean, dry and free from dust, loose mill scale, looserust, oil and any other
condition preventing good adhesion. Grease and ash should be removed and the surface should be
clean. This coating has a certain anti-rust effect on steel components, but for exterior or humid
environment, steel surface still need to be coated with anti-rust primer. Surface priming: in the daub
coating must be priming, priming material with portable spray gun spraying, thickness of 2-3mm, the
bottom is basically uniform. Primer material preparation: according to the special glue: paint: water
=1:3:2.1 advised (water consumption slightly adjusted for spraying).
Coating tools: manual application, the bottom of the handheld spray gun spraying, muzzle diameter of
8-10mm, air compressor air pressure of about 0.4 mPa.
Mixing: The paint is a powdery mixture, mixed with an appropriate amount of tap water in a low-speed
mixer to form a thick slurry. (Note: water should be added first and then add powder, the two can
not be reversed) Its consistency should be suitable for application (the consistency is generally about
8cm), mixing time 6 minutes, not too long, mix well. The proportion of water used is about 1: 0.86.

Thickness: According to the fire protection requirements, the coating thickness is selected in the range of 0.8-2.8cm, and the
thickness of each application is controlled within 1cm, and the interval between secondary applications is generally 24 hours
(temperature 20°C). The interval time between different ambient temperature and humidity should be adjusted accordingly.
Environmental: During the construction of the paint and within 24 hours after construction, the ambient temperature shall not be
lower than 4°C. Like ordinary cement mortar, it suffers frost damage before solidification, but after the coating has solidified and
partially dried, the coating can resist frost damage.
Reinforcement treatment: This coating is reinforced with steel wire, taking a galvanized steel wire (wire diameter 0.6 ~ 0.7mm),
winding a circle at 10cm intervals on the steel beam, and winding the web of the steel beam for another week. In the case of large steel
components or incomplete coating of structural shapes, as well as under conditions of vibration and mechanical collision, in order to
ensure the durability of use, it is recommended to use reinforcement measures such as bandaging steel wire mesh.
Slurry use time: the slurry should be mixed with the use, at room temperature should be used up within 1 hour, the base material
should be used up in 1.5 hours (the weather is hot, shorter), do not store too long, resulting in the slurry lining on the substrate
adhesion and other adverse effects.
Exterior decoration: the coating is grayish white after hardening, and after the coating is dried, the surface can be painted with
architectural paint decoration.
Other matters that have not yet been built can be carried out with reference to the general lightweight aggregate plastering
construction process.
Once the packing is opened, it must be used, and the paint that is damp and agglomerated must not be used. This spray should
be constructed by designated professional construction workers, and LCF can provide construction technical guidance for the
construction application unit

Substrate prepartion
Datasheet
Aerogel, a Guinness record set for 15 times, is known as the “miracle material that changed the world”
and is also an ideal fire proof green new material. Aerogel is a three-dimensional continuous porous
material composed of nanopores and nanos keleton, and its unique structure gives it super fire and
heat insulation performance. The aerogel fireproof coating series products produced by LCF, a new
kind of indoor inflatable steel structure fireproof coating which is made of emulsion as film forming
material, adding fireproof flame retardant material, high quality filler and auxiliary agent and pure
water based, eco friendly.
Application for steel structure components in industrial, commercial and residential buildings
Fire resistance up to 120 mins in accordance with ASTM E119 Durability up to over 10 years Eco
friendly, no harm to human body Thinner film, to achieve the same rate, the thickness of aerogel film
is less than 1/3 of the other material.
Zinc-rich epoxy antirust primer
The substrate shall be clean, dry and free from dust, oil and any other condition preventing good
adhesion. The surface of the steel base material of the steel structure should be strictly dewatered
and derusted, and the sand blasting derusting reaches the grade of Sa2.5, and the manual derusting
reaches the grade of St3 and above, and the surface of the derusting is finished with anti – rust primer
for anti - corrosion treatment. It is necessary to detect the miscibility of anti-rust paint and fireproof
paint on the surface of the substrate. It is not allowed to use anti-rust paint with high brightness
that does not meet the requirements, so as not to affect it adhesion of fire retardant coatings. In
case of high brightness and high hardness anticorrosive paint, it should be polished or coated with an
intermediate paint transition.

Coating work
This product is water-based coating, not suitable for construction in rain or snow weather or dew on the surface of steel components.
Intumescent coating is interior using recommended, cementitious coating is recommended for exterior projects. This coating is
forbidden to be mixed with other coatings and oil crops. Construction maintenance period should prevent the sun, rain, dew invasion
or mechanical damage.
Coating should be fully stirred before construction, such as too thick add proper amount of water dilution. The theoretical coating
amount of coating per square meter per spray 1mm dry film thickness is 1.0~1.2kg.
The construction should be carried out above 50C, the relative humidity of air ≤85%, brush coating, roller coating, spraying, each time
the thickness of the construction is not more than 0.2mm is appropriate, until the coating is basically dry (gently push the coating
does not move), can be carried out next brushing, until the specified thickness.
After the fireproof coating is completely dry, spray or brush special protective finish coat on the outer surface of the coating.
