Bilt Hamber Dynax-S50 is an extreme duty anti-corrosion wax for cavities, voids and long term protection.

Dynax-S50 is a high-performance anti-corrosion wax that provides exceptionally long-lasting protection to steel surfaces. It creeps into welded seams and seals surface defects. Dynax-S50 forms a soft, brown, wax-like film that self-heals in the event of disruption. It is also able to arrest existing corrosion and to provide long-term protection to pre-corroded and corrosion-free surfaces. 

The 750ml aerosol is supplied with a 600mm reusable application lance.

If multiple aerosols are purchased, one appliction lance per 2 aersols will be supplied.


  • Class-leading long-term protection for cavities, voids, chassis, doors, mud traps machinery, boats etc.
  • Resistant to changing conditions found in cavities, others are not
  • Self-healing, protects even if film is cut
  • Clings to vertical surfaces
  • Displaces moisture
  • Kills existing corrosion
  • Deeply penetrates flanges and folded seams
  • Easy to use - atomises superbly
  • Low odour
  • See-through coating with brown tint
  • Provides lubrication
  • Available in ready to use modular injection system

Dynax-S50 has been proven to substantially outperform competitive material in salt-spray trials under conditions of ASTM B117.

Dynax-S50’s soft-film is optimised for enclosed cavities where extremely corrosive conditions develop. Dynax-S50 is also recommended for protection of valuable machinery and components in transit, machine tools, moulds etc. Dynax-S50 can be removed using suitable solvent. Dynax-S50 is not formulated for prolonged exposure to ultra-violet (UV) light.

The advanced metal seeking anti-corrosion molecules which form Dynax-S50 are able to displace water, so even damp surfaces can be protected, these same molecules arrest and prevent corrosion even on already rusty surfaces and provide remarkable self-healing abilities if the film is damaged. Whilst Dynax-S50 is primarily a cavity rustproofing compound it’s also able to prevent corrosion in a multitude of mud traps and water collecting voids. Dynax-S50 has been used with superb results to protect voids and cavities in steel boats, vessels, offshore installations and other steel structures subject to severely corrosive atmospheres.

How to use Bilt Hamber Dynax-S50

The pressurised giant-sized Dynax-S50 aerosol dispenser accepts interchangeable heads: The 60cm cavity injection lance has a precision fluid-tip to deliver, at high-pressure, a dense, finely atomised circular mist of Dynax-S50 ensuring 360 degree coverage of box sections and cavities. For accessible areas the extension tube is removed and a solid-cone spray pattern actuator simply clipped in its place. The pressurised aerosol dispensers contain a useful 750 ml (3/4 of a litre) of material.

Use a brush, roller or spray to apply Dynax-S50. Atomisation into enclosed cavities and voids is recommended to ensure thorough coverage of all surfaces. Dynax-S50 contains highly polar corrosion inhibitors that are able to displace surface moisture.

Dynax S-50 is tolerant of a broad range of application pressures and will form a coherent film upon application.
Dynax S-50 will increase in viscosity at low storage temperatures; it is recommended to place container, or 
aerosols in a room at around 15oC for 24 hours prior to use where deep crevice protection is required.
Ensure that cavities are left unclosed for a period of 48 hours to allow the escape of carrier materials before 
bunging or stopping.

Dynax-S50 will provide excellent protection at a wide-range of film thickness – aim to achieve a uniform dry-film thickness of around 50 microns. The tolerance of the material to maintain protection at very low film thickness makes Dynax-S50 the ideal choice where surface inspection is not easy or where uniform coatings are simply not possible.

For non-aerosol dispensed Dynax-S50, warming the container (loosen cap first) by standing in a hot water bath will further reduce viscosity and is beneficial where deep crevice protection is required.
