For fire protection of metal structures

General information about Stabiterm-221

Stabiterm-221 fire protection thick-layer composition is a one-component mixture of fireproof and heat-resistant agents, a binder, and functional additives. 

Application features

It is used for structural fire protection of metal structures in industrial and civil construction. The composition can be used both indoors or outdoors under shelter. It complies with fire safety requirements established in GOST R 53295-2009. To use Stabiterm-221 in the open air, it is necessary to ensure the application of protective weatherproof paint.

The principle of action is based on the formation of a heat-insulating layer on the surface of a metal structure as a result of its application. Stabiterm-221 fire protection composition is produced in a ready-to-use form.

Unique properties and advantages of Stabiterm-221


Solid structure

Smooth, solid, white fire protection coating with a high degree of mechanical resistance.


Low consumption

The dry solids content of at least 70% reduces the consumption of the product per square meter of surface to which it is applied.


Reduces the labor costs

It is possible to apply up to a 2 mm layer in one pass, which significantly reduces the labor inputs.



It is compatible with primers produced by various Russian and international manufacturers. This is ensured due to the high degree of adhesion of fire protection coating to the covered surface.


Up to 25-year warranty

Warranty periods for the coating (if the application conditions are observed) are as follows: indoors — 25 years, outdoors under a protective coating — 15 years.


Application devices

It is applied using an airless sprayer.

  • It is used for structural fire protection of metal structures.
  • Recommended for the protection of metal structures against fire with the required fire resistance rating of R 90, 120, or 150 minutes, and the effective metal thickness of less than 5.8 mm.
  • It has the intrinsic heat-insulating capability, which prevents from the heating of metal structures in case of fire.
  • Under the influence of high temperatures (from +200°C and more), it forms a porous heat-insulating layer providing additional protection.
  • The color is white. Can be tinted in pastel colors.
  • Ready-to-use one-component composition.
  • Fire resistance rating is from 90 to 150 minutes for an effective metal thickness of 2.4 mm and more.
  • Application temperature is from 5°C to 40°C.
  • The guaranteed shelf life in an original unopened package: 12 months. Packing: 17 kg.
