Description

Advanced Anti-Corrosion Protection

Würth Wax Underseal is a solvent-containing, wax-based protective compound engineered to provide long-lasting corrosion resistance. Its unique formulation penetrates deeply into seams, gaps, and edges, forming a durable barrier that resists water, salt, and environmental influences. Once cured, the coating maintains a slightly sticky surface, which ensures ongoing flexibility and self-healing of minor abrasions.

Temperature Resistance and Versatility

With a service temperature range of -25°C to 180°C, this underseal performs reliably in both harsh cold climates and high-temperature environments. This makes it ideal for use in automotive, industrial, marine, and maintenance sectors. Unlike many coatings, it retains stability on metallic surfaces without flaking or becoming brittle over time.

Universal Application Areas

Designed for use wherever corrosion poses a threat, Würth Wax Underseal can be applied to vehicles, machines, machine parts, and structural metalwork. Common industries include:

  • Automotive and bodywork construction - wheel arches, underbodies, seams, and panel joints.
  • Bus and trailer construction - large-scale metal frameworks and exposed sections.
  • Shipbuilding and marine maintenance - areas vulnerable to constant moisture and salt.
  • Workshops and garages - protection of tools, machinery, and structural components.
  • General industry - any metallic surfaces at risk of corrosion.

Important Application Notes

This product cannot be painted over once applied. For best results, apply to a clean, dry, and degreased surface. Shake thoroughly before use to ensure consistent wax distribution.

  3. Apply using airless or airmix spray guns, or with a pressure cup spray gun (3-4 bar).
  4. Alternatively, the product can be applied by dipping, rolling, or brushing.
  5. Apply evenly to achieve a dry layer thickness of at least 50 μm
  6. Allow to dry under recommended conditions before subjecting to full stress.
  7. After application, turn aerosol can upside down and spray until valve is empty.
  8. Clean contaminated surfaces and tools immediately with suitable solvents before drying.

Usage Notes

  • Recommended application temperature: 15-25°C.
  • Do not paint over the coating.
  • Stir/shake well before use to ensure uniform application.
  • Shelf life: 24 months from production when stored correctly.
