Two-component closed-cell foamNo external power supply requiredMoisture resistant after curing
Applications
- Sealing air barriers in mining plants
- Restricting airflow by closing leaks around electrical and installation runs and other areas requiring airflow restriction
- Filling empty spaces (gaps, cavities)
- Making plugs in boreholes
- Preventing water outflow
- Insulation of cooling containers
- Thermal and acoustic insulation
Properties
- Two-component closed-cell foam
- No external power supply required
- Moisture resistant after curing
- Gas-tight
- Thermally stable
Advantages
- Excellent adhesion to most substrates found in mines: coal, shale, concrete, wood, metal
- Effective for hard-to-reach application areas thanks to spray gun
- Easy to transport
- Rapid expansion and short initial curing time allow use even with very intense airflow
- Cured foam does not shrink or collapse
