Denso tape is a cold applied tape which remains plastic over a wide temperature range. The tape is non-hardening and non-cracking. It is highly resistant to mineral acids, alkalis, salts and micro-organisms and highly impermeable to water, water vapour and gases. The tape provides corrosion protection for pipes, valves, joints, metal surfaces, cable above and below ground or under water. Seals against ingress of water, gas, chemicals and grout.
