Denso, Inc., a global leader in corrosion prevention and sealing technologies, is proud to highlight its Densyl Tape, a high performance, multipurpose petrolatum tape designed to provide unparalleled corrosion protection for steel pipes, flanges, valves, fittings, and other surfaces.

Engineered to excel in extreme environments ranging from cold to tropical heat, Densyl Tape is the go-to solution for industries requiring durable and reliable surface protection.

Densyl Tape is composed of a non-woven synthetic fabric carrier saturated with petrolatum and inert siliceous fillers, providing durable and long lasting corrosion protection. It meets the NACE RP0375-2006 standards, ensuring compliance with industry benchmarks for corrosion protection. This tape can be applied to marginally prepared surfaces (SSPC SP 2-3), allowing for efficient installation without extensive surface preparation. Its ability to conform to irregular shapes and profiles offers flexibility in protecting complex surfaces like valves and flanges.

Densyl Tape is UV resistant and can be applied to cold, wet surfaces, enabling installation in challenging environmental conditions. The tape is unaffected by water, acid, salts, or soil organics, providing robust protection against various corrosive substances. Additionally, it safely encapsulates lead paint, ensuring environmental safety. Being solvent-free, Densyl Tape offers an environmentally friendly option.

The tape is easy to apply across a wide temperature range, from cold to tropical conditions, facilitating use in diverse climates.

Once applied, it is ready for immediate service, reducing downtime and increasing operational efficiency. It can be applied both above and below ground, offering versatility in various installation environments.

Densyl Tape is often used in combination with Denso Glass Outerwrap, which provides additional mechanical and impact strength for applications requiring enhanced protection. Denso Glass Outerwrap is particularly beneficial for underwater, underground, and above-ground installations, offering a robust outer layer that complements the corrosion protection offered by Densyl Tape. This combination enhances the overall durability and resilience of the corrosion protection system, making it suitable for environments where increased mechanical protection is necessary.

With its proven track record and versatility, Densyl Tape continues to be a trusted choice for industries seeking reliable corrosion protection solutions. Denso, Inc. is a global leader in corrosion prevention and sealing technologies. With decades of experience, Denso specializes in delivering innovative, high performance solutions tailored to meet the needs of industrial and infrastructure applications worldwide.
