Performance

Product advantages

High UV-resistance.
Ceaseless adhesion to application surface ensures transparent film.
Thanks to aliphatic structure, does not discolour or blench upon exposure to sunlight.
Easy to apply.
Removes the possibility of leakage since it doesn’t cause any joint formations.
High adhesion.
Preserves mechanical characteristics in temperatures between -40°C and +80°C.
High chemical and mechanical resistance.

Application range

Areas of use

Indoor and outdoor places
Surfaces requiring high abrasive strength
Areas with intense pedestrian traffic
Stadia, parking lots
Materials such as marble, ceramics and natural stones
Roofs, terraces, verandas and balconies
Industrial floors
