Denso Tape

Cold Applied Anti-Corrosion Petrolatum Tape

Denso Tape is the industry leading anti corrosion tape as used by British Gas for sealing underground joints against moisture. It protects pipes, fittings and similar structures from corrosion above the ground, below the ground and even if they are immersed. It is a cold applied tape, based on a synthetic fabric which is impregnated and coated with a neutral petrolatum compound and inert siliceous fillers. It is non-hardening and non-cracking. It is highly resistant to mineral acids, alkali's, salts and micro-organisms and highly impermeable to water, water vapour and gases. Used for the protection of buried or exposed pipes, rods, cables, valves and metal fittings from corrosion.

*For buried applications apply this tape with a 55% overlap to provide double thickness.

Denso Tape was the first petrolatum tape manufactured in the UK under licence by Winn & Coales (Denso) Ltd.&Please note the we only offer OFFICIAL Denso Tape and will never offer inferior alternatives.

A cold applied tape which remains plastic over a wide temperature range. It is non-hardening and non-cracking. It is highly resistant to mineral acids, alkali's, salts and micro-organisms and highly impermeable to water, water vapour and gases. Used for the protection of buried or exposed pipes, rods, cables, valves and metal fittings from corrosion.
