SiCoat – effective
all-purpose intumescent
fire-protection material

SiCoat is effective all-purpose intumescent fire-protection material that can be used for fireproofing of construction elements (pillars, girders, doors, air ducts, cable conduits etc.) made of steel, wood, concrete, polymer, composite materials etc.

SiCoat allows improving the flammability class of polymers or reaching almost any fire-resistance rating.

While most of the fire-protecting products have only one action, SiCoat is very effective due to its triple action.



Low-temperature intumescence (200 °C) creates an effective thermal insulating shell of expanded silicate foam

Ablation effect

Ablation effect cools the protected surface down to 100 °C

Thermal absorption

Aggregative transition (glazing) of the surface turns it into a porous glass at 700 °C and consumes most of the heat energy

How Does SiCoat Work?

SiCoat is sodium hydro-silicate in the form of colloid or hard gel powder. Under the temperature of 200 °C and higher intumescence of SiCoat forms a hard shell of silicate foam with very low thermal conductivity (λ=0.045 W/m °K).

SiCoat contains chemically bound (crystallization) water up to 20% by weight, and during the heating water releases, boils and cools the surface down to 100 °C.

The ablation effect of SiCoat is similar to the one used in flight recorders and spacecraft shells. This ablation effect allows the surfaces protected with SiCoat not getting hotter than 100 °C during a significant time interval.

During the fire, the SiCoat surface gets glazed and consumes most of the heat energy protecting the subject.

Standard Fire Curve

3 formats of SiCoat are used for fire protection:

SiCoat C

SiCoat C can be applied with a brush, paint roller, spatula, sprayer or cartridge.

It can be used for protection of surfaces, for gluing or tightening joints of soft refractory materials, fire-protecting and thermal insulating mats, for tightening joints/collars of hot air ducts and pipelines.

Adding SiCoat to composite mat used for inner lining in car production allows to significantly reduce combustibility and burning behavior of the whole car.

SiCoat B

SiCoat B is a roll material consisting of 3 layers:

  • The base of a nonwoven or woven fabric – vlies, cotton, basalt etc.
  • Colloidal SiCoat layer
  • Liner or separating film

SiCoat B fire-protecting bandage is an all-purpose solution for metal, wooden, polymeric or composite construction elements made of steel (pillars, girders, beams etc.) or wood.

It is able to improve fire-endurance of air ducts, cableways, doors and gates.

The range of possible applications for SiCoat B also includes fire protection of concrete ceilings of parking zones and other communal areas, equipping fire-protecting shells for pipelines and cableways in walls and floors, improving fire-endurance of thin-wall metal elements (e.g. floor between aircraft baggage bellyhold and passenger cabin).

SiCoat B fire-protecting bandage has a very convenient application. It can be applied to the surface as one operation reaching the fire-protecting layer of any thickness. Just unseal the bandage and layer by layer apply it to the surface removing the liner.

The application process is safe, creates no splash, no drops, no bounce and no toxic emission. SiCoat B can be applied in living or industrial areas even during their operation.

SiCoat B is the ideal solution for improving fire-endurance of elements that among REI requirements have the main focus on I – loss of thermal insulating ability.

Due to the ablation effect the temperature of surfaces protected with SiCoat B can remain under 100 °C during a significant time interval.

SiCoat P

SiCoat P is sodium hydro-silicate hard gel powder that contains up to 20% of chemically bound (crystallization) water and can be used as active filler for:

  • Fire-protecting paints/varnishes based on alkyd and/or acrylic resins
  • Fire-protecting coat gel based on a polyester resin to improve fire-endurance of fiberglass elements in shipbuilding, aircraft construction and railway coach manufacturing interior trim
  • Protection of thermoplastic polymers (PE, PP, PVC) to get fire-resistant cable sheaths and cable ducts

If you have any special needs in fire-protection for a specific project, element or material, we will be happy to discuss them and to find the proper solution for you.
