HYPERDESMO ® -PB-2K is a two-component, fast-setting, liquid polyurethane-bitumen membrane. It creates a very flexible coating that strongly adheres to many types of substrates, with excellent mechanical and chemical properties. The composition is based on elastomeric hydrophobic polyurethane resins extended with chemically polymerized pure bitumen. Application using a brush, roller, notched trowel or hydrodynamic spray. Minimum consumption 1.0-1.5 lt/m 2 .
APPLICATION
- Waterproofing and protection of surfaces such as:
- Green roofs ,
- Foundations and basements ,
- Light roofs made of metal or cement board ,
- Wet rooms (bathrooms, kitchens) – under tiles ,
- Asphalt membranes, EPDM, TPO/FPO ,
- Water reservoirs ,
- Drainage and irrigation channels ,
- Bridges and underpasses ,
- Bridge platforms ,
- PUR foam thermal insulation .
FEATURES AND BENEFITS
- Two-component, liquid polyurethane-bitumen membrane – quick setting and excellent adhesion to various substrates.
- Resistance to root growth – ideal for use on green roofs.
- Self-flowing formula – can be used as a sealing mass for expansion joints.
- Crack bridging – the membrane remains flexible and effectively covers gaps in the substrate.
- Resistance to high and low temperatures – operating range: from -40°C to 80°C, thermal shock up to 200°C.
- Excellent mechanical and chemical resistance – high resistance to abrasion, friction and chemicals.
- Good water vapour barrier – limits the penetration of moisture into the substrate.
CONSUMPTION
- Minimum total consumption: 1.0-1.5 L/m² .
PACKAGING
