IZOMAX® BAND 120
IZOMAX® Band F is a three-layer sealing tape with a thermoplastic elastomer (TPE) coating between two polypropylene non-woven layers. It has high elongation in the transverse direction and is dimensionally stable lengthwise; this structure allows the tape to accommodate joint movement while being installed without tension along its length. Its double fleece facing provides high adhesion to tile adhesive and liquid waterproofing materials.
Fields of Application
• Interior wet areas with medium to high exposure to non-pressurised water (classes W2-I and W3-I according to DIN 18534) — domestic bathrooms, public shower rooms
• Industrial kitchens additionally exposed to chemicals
• Swimming pools and surfaces subject to constant water pressure
• Wall-to-floor junctions and inside/outside corner details
• Movement joints beneath ceramic and natural stone coverings
• Concrete, screed, cement-based render, gypsum board and aerated concrete substrates
Advantages
• Accommodates joint movement with 300% transverse elongation
• Dimensionally stable lengthwise; installed without tension
• Double fleece facing provides high adhesion
• At only 0.66 mm thick, it does not raise the covering level
• Suitable for interior and exterior use, including pools under constant water pressure
• Resistant to dilute acids, alkalis, salt water and chlorine
