Product Description
PROOF RC 2K is a fast-curing, two-component, bitumen-enriched, polyurethane-based liquid material. It adheres strongly to almost all types of surfaces, forming a highly elastic film.
Its chemical and mechanical resistance is excellent.
It is based entirely on elastomeric hydrophobic polyurethane resin, supplemented with chemically polymerised pure bitumen.
Application Areas
- Floors, foundations, roofs
- Green roofs and planting beds, gypsum and cement panels
- Polyurethane insulation foams
- Asphalt membranes/EPDM membranes
- Bathrooms (under tiles), verandas and balconies (under tiles)
- Lightweight roofs made of metal or fibre cement
- Water tanks (excluding drinking water tanks), bridge platforms
- Cut-and-cover tunnels, irrigation channels
Advantages
- Its elasticity is 2000%.
- Mixing the components in equal amounts, 1:1 by volume, makes the process easier.
- Cures quickly.
- Can be applied in thick coats; does not form bubbles.
- Unmixed components left over from the application amount can be stored for later use.
- Due to its low modulus, its crack-bridging ability is excellent.
- Adheres perfectly to almost all types of surfaces, with or without a primer.
- Although it does not need to be thinned, SOLVENT can be used depending on the conditions.
- Thermal resistance is excellent; the product never softens. Maximum service temperature is 80 °C, maximum shock temperature is 200 °C.
- Resistant to cold. The film retains its elasticity down to -40°C.
- Has excellent mechanical properties: high elongation capacity, tensile, tear and abrasion strength.
- Shows good resistance to chemicals.
