INVAMAT 611 THERMAL-EXPANDING FIREPROOF MASTIC
INVAMAT 611 THERMAL-EXPANDING FIREPROOF MASTIC —
to seal through holes in brick, concrete, foam concrete and other non-combustible materials to prevent fire from entering through the barrier. Application: filling the free space in holes made in the barriers, after laying cables (single or harnesses), pipes from combustible materials, as well as metal pipes.
RECOMMENDED GEOMETRIC RATIOS:
- The maximum hole diameter is 200 mm (or the maximum area is 300 cm²);
- The maximum diameter of pipes made of non-combustible materials is 50 mm;
- The maximum filling (in% of the hole area) is 60.
RECOMMENDATIONS FOR USE:
Clean the hole of dust and dirt.
Fill the free space of the hole, including the gaps between the cables, with INVAMAT-611 mastic. The depth of filling with mastic is 40±5 mm on each side. (If the barrier thickness is more than 100 mm, to save the mastic, the inside of the hole can be filled with «Rockwool» mineral wool). Level the sealing surface with a spatula until the mastic dries. To improve the plasticity when leveling, wet the mastic surface with water.
The main performance characteristics are reached after 48 hours.

The effect of using INVAMAT 611 mastic for sealing of cable penetrations is achieved due to formation of a foamed structure that limits the spread of fire, toxic and corrosive combustion products.
ADVANTAGES OF FIREPROOF MASTIC
Mastic for cable penetrations is not inferior in performance to the best developments of leading manufacturers of similar products, has an affordable price and a number of the following advantages:
- Simplicity and ease of use. The product is ready for use and easily dyed after drying. In addition, the installation of cable penetrations with mastic INVAMAT 611 does not require special equipment and high qualification of personnel. The resulting structures allow the laying of additional lines.
- Plasticity of dried material. The sealing surface retains its integrity during the settlement of buildings/structures and laying of additional cable lines.
- High tightness. The mastic and embedded cable penetrations do not allow combustion products, water, gas to flow through.
- Safety. The product is non-toxic, does not contain solvents and halogens.
- Durability. Long service life is due to a high margin of safety, chemical and weather resistance.
RECOMMENDATIONS FOR THE APPLICATION OF UNIVERSAL CABLE PENETRATION
