Duralac Green Jointing Compound

Duralac Green is a high-performance, chromate-free jointing compound designed to prevent galvanic (electrolytic) corrosion between dissimilar metals. This environmentally friendly alternative to Duralac Yellow forms a durable barrier that inhibits anodic corrosion, making it ideal for marine, automotive, construction, engineering, and aerospace applications.

Supplied as a single-pack, air-curing compound, Duralac Green is ready to use straight from the container and requires no thinning. It provides long-lasting protection in harsh environments, particularly where moisture, saltwater, or marine atmospheres accelerate corrosion.

Features & Benefits

  • Chromate-free, environmentally friendly formulation.
  • Prevents galvanic corrosion between dissimilar metals.
  • Superior adhesion to metal and non-metal surfaces.
  • Greater resistance to salt spray than traditional Duralac Yellow.
  • Tough, flexible seal with excellent water resistance.
  • Low water absorption and low water solubility for long-term protection.
  • Ready to use – no mixing or thinning required.
  • Air-setting formula remains tacky long enough for effective joint sealing.
  • Two-year shelf life when stored below 20°C in unopened containers.

Suitable Materials

Duralac Green provides excellent protection where metals come into contact with:

  • Aluminium and aluminium alloys
  • Magnesium alloys
  • Steel
  • Wood
  • Synthetic resin composites
  • Leather
  • Rubber
  • Fabrics
  • Other dissimilar construction materials

Typical Applications

Duralac Green is recommended wherever dissimilar metals are joined together or exposed to moisture and electrolytes.

Ideal for use in:

  • Marine fittings and boat construction
  • Aluminium structures and extrusions
  • Vehicle and trailer manufacturing
  • General engineering projects
  • Construction and architectural metalwork
  • Aerospace assemblies
  • Coastal installations exposed to salt-laden air

Common applications include:

  • Mast fittings
  • Winches
  • Antenna and aerial mounts
  • Battery installations
  • Bolts, screws and rivets
  • Aluminium plates and extrusions
  • Aluminium-to-steel connections

Application

Duralac Green is supplied ready for immediate use and should not be thinned.

Apply a thin, even coat using a brush to the mating surfaces before assembly. As the solvent evaporates, the compound becomes touch dry while remaining tacky for a period, allowing joints to be assembled under pressure to create a complete protective seal. For best results, components should be assembled before the compound fully cures.

Performance

Its durable synthetic resin formulation provides outstanding adhesion and flexibility while resisting water washout, even under high-pressure water exposure. The compound remains effective in demanding marine and industrial environments, helping to extend the service life of fasteners, fittings and structural components by preventing electrolytic corrosion.
