DEFINITION
Two-component, solvent-free, spray-applied, hybrid polyurea membrane. Applied with a high-pressure, dual-mixer pump for waterproof coating on bridge decks and flat roofs.
APPLICATION AREAS
Purtop 400 M, with its high tear strength, exceptional flexibility, and chemical resistance, is suitable for use as a waterproofing membrane on large flat roofs and bridge decks. Additionally, due to its special characteristics, it can be used in the waterproofing of both new and existing structures.
Some application examples:
- Waterproofing of garden terraces and inverted roofs.
- Waterproofing of flat roofs made of sheet metal.
- Waterproofing of steps and seating areas in stadiums (with appropriate finishing product).
- Waterproofing of bridge and viaduct decks.
ADVANTAGES
- Purtop 400 M has excellent adhesion strength and, after application, forms a continuous, strong, and flexible membrane.
- Solvent-free.
- Instant waterproofing (after 2 minutes) and quick foot traffic access (after 15-20 minutes).
- Excellent tensile strength (according to DIN 53504, 14 N/mm²).
- Outstanding tear resistance (according to ISO 34-1, 55 N/mm).
- High crack-bridging capacity even at low temperatures, both statically and dynamically.
- Over 400% elongation capacity (DIN 53504).
- Excellent resistance to alkalis and diluted acids.
- Rapid reaction of the product when applied by spraying; gel time < 6 seconds at +70°C.
- Does not require reinforcement.
- Does not create additional load on load-bearing structures.
- The product is completely inert after application.
