Product Description
PROOF 2K Y is a two-component thixotropic coating material made of high-quality elastomeric polyurethane resins. It is solvent-free. After polymerisation it forms a hydrophobic, elastic and strong membrane. It is especially recommended for waterproofing water tanks. PROOF 2K Y also provides a continuous, integral coating on surfaces with details such as chimneys, antennas or pipes.
When the surfaces of the tanks are exposed to direct sunlight, the colour of the material fades. However, this is purely a matter of appearance; waterproofing and protection performance are not affected in any way.
Application Areas
- Water tanks made of concrete/steel-reinforced concrete, steel or other materials
- Precast concrete tanks, drinking water tanks
- Tanks subject to shrinkage and expansion movements
Advantages
- Adheres perfectly to almost all types of surfaces.
- Since it is solvent-free, it can be applied easily in enclosed areas.
- Has very high hydrophobic and hydrolysis resistance.
- Performs over a wide temperature range. Heat resistance is between -40°C and 90°C.
- Shows effective resistance to chemicals.
- The most ideal solution for water tanks in terms of cost-performance.
- Special primers, top coat materials and colouring pastes are available.
Application
The surface should be cleaned, if possible using pressurised water; oil, grease, fuel and paraffin residues must be removed, and the surface must also be completely freed of release agents, cement residues, chips, loose particles and cured membranes.
For tanks made of materials other than concrete, please contact our technical department.
