In the demanding worlds of industrial maintenance, pipeline integrity, and marine applications, protecting metal assets from degradation is paramount. Anti-corrosion tapes are a critical engineered solution designed specifically for this purpose. It is a laminate material, typically consisting of a robust backing, a specialized corrosion-inhibiting compound (often a petrolatum or butyl-based grease), and a protective release liner. When applied to cleaned metal surfaces, it creates a continuous, self-healing, and waterproof barrier that actively prevents corrosion by shielding the substrate from oxygen, moisture, electrolytes, and other corrosive agents. Unlike simple vinyl or PVC tapes, true anti-corrosion tapes are formulated for long-term, below-grade, or submerged protection, making them indispensable for safeguarding pipes, joints, fittings, bolts, and structural steel in harsh environments.
Kaxite has developed a range of anti-corrosion tapes built on decades of material science expertise. Our products are engineered not just to meet but to exceed industry standards for durability and protection.
Selecting the correct tape for your specific application requires an understanding of its technical parameters. Below are the detailed specifications for the core Kaxite Anti-Corrosion Tapes series. For specialized products, please consult our technical datasheets.

Q: What surfaces can I apply Kaxite anti-corrosion tapes to?
A: Kaxite tapes are designed for use on prepared steel, ductile iron, and concrete surfaces. They adhere excellently to primed steel, polyethylene (PE), polypropylene (PP), and fusion-bonded epoxy (FBE) coatings. They are not recommended for dynamic joints or surfaces with constant flexing. Always consult the technical data sheet for substrate compatibility.
Q: How do I properly prepare the surface before application?
A: Surface preparation is critical for long-term performance. The metal surface must be clean, dry, and free of rust, scale, oil, grease, and dust. For optimal results, abrasive blast cleaning to a minimum standard of Sa 2½ (ISO 8501-1) or power tool cleaning to St3 is recommended. Remove all loose material. The surface temperature should be at least 3°C above the dew point during application.
Q: What is the correct application method?
A: 1) Unwind the tape and remove the release liner. 2) Place the tape at one end of the area to be protected, ensuring the adhesive side makes full contact with the substrate. 3) Apply firm, consistent pressure while wrapping, maintaining a 55% overlap (minimum 50mm overlap on all seams). 4) For pipes, spiral wrap with appropriate tension to avoid wrinkles. 5) Use a roller or hand pressure to eliminate air pockets and ensure intimate contact. No priming is usually required.
Q: Can this tape be used for buried or submerged pipelines?
A: Yes, the Kaxite Heavy Duty (KX-ACP-2) and Marine Grade (KX-ACP-3) are specifically formulated for direct burial and intermittent or permanent immersion in fresh water, seawater, and most soils. Their high dielectric strength and resistance to cathodic disbondment make them an excellent choice for use with impressed current cathodic protection systems.
Q: How long does the protection last?
A: The service life of Kaxite anti-corrosion tapes is designed to exceed 30 years when applied correctly to a properly prepared surface in accordance with the specified environmental conditions. Its passive, non-drying nature means it does not degrade or lose effectiveness over time unless mechanically damaged.
Q: Is the tape resistant to UV rays and sunlight?
A: The standard grade is for temporary above-ground use or must be coated/covered if exposed to sunlight for extended periods. Our Marine Grade (KX-ACP-3) features a UV-stabilized black outer layer designed for prolonged exposure to sunlight, making it suitable for above-grade piping, offshore structures, and splash zones.
Q: What are the storage conditions for the tape?
A: Store rolls in a cool, dry place away from direct sunlight, heat sources, and moisture. The ideal storage temperature is between 10°C and 25°C. Store rolls vertically on their ends to prevent deformation. Rolls are typically supplied in protective shrink-wrapping; keep this on until ready for use.
Q: Does Kaxite offer tapes for specific applications like pipe joints or elbows?
A: Absolutely. In addition to standard rolls, Kaxite manufactures pre-formed shapes such as pipe wrap tapes for joints, mitered sheets for elbows and tees, and wide sheets for large structural areas. These are designed for faster application and complete coverage on complex geometries.
