The structural fire protection system BST KMR is a combined two-layer coating that includes the heat-protective material BST MT and the fire-retardant thermally expanding material BST MR.
BST KMR increases the fire resistance of load-bearing metal structures to 120 minutes.
The coating is not moisture resistant.

| Degree of expansion, %, not less | - / 1400 |
| Thinner, not more than 5% by weight | xylene/xylene |
| Fire retardant efficiency, min | 90 | 120 | ||
| Reduced metal thickness, mm | 3,4 | 3,4 | ||
| BST MT | BST MR | BST MT | BST MR | |
| Thickness of fire retardant coating, mm | 2,0 | 2,0 | 2,0 | 3,25 |
| Theoretical consumption, kg/m² | 3,44 | 3,45 | 3,44 | 5,61 |
- Surfaces must be dry and free of dust, degreased, primed and free from defects.
- Before using BST MT and BST MR, mix with a mechanical stirrer to a homogeneous consistency for 3-5 minutes.
- Both materials are applied layer by layer - BST MT from 3 to 4 layers, BST MR from 2 to 4 layers, application is recommended to be done by airless spraying or manually using paint brushes.
- The thickness of the first wet layer when applying BST MT should not exceed 500 microns, when applying BST MR it should not exceed 400 microns. All subsequent layers must be applied with a recommended thickness of one wet layer of no more than 1800 microns, both in the case of BST MT and in the case of BST MR.
- Interlayer drying from 6 hours. Complete drying of the coating takes 10 days.
- Application temperature from -10°C to + 40°C, relative humidity no more than 85%.
- After application, wash all working tools and equipment with xylene, P5, P4.
- When working with BST MT and BST MR, it is necessary to use personal protective equipment.
- BST MT is packaged in sealed metal buckets weighing 15 kg.
- BST MR is packaged in sealed metal buckets weighing 22 kg.
- BST MT and BST MR should be stored and transported in a dry place, protected from direct sunlight, at temperatures from - 40°C to + 40°C.
- The shelf life in original, unopened packaging is 12 months from the date of production, subject to compliance with storage conditions.
