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 S-50 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.
dynax S-50 has been proven to substantially outperform competitive material in salt-spray trials under conditions of ASTM B117.
dynax S-50's soft-film is optimised for enclosed cavities where extremely corrosive conditions develop. dynax S-50 is also recommended for protection of valuable machinery and component in transit, machine tools, moulds etc. dynax S50 can be removed using suitable solvent. dynax S-50 is not formulated for prolonged exposure to ultra-violet (UV) light.
The advanced metal seeking anti-corrosion molecules which form dynax S-50 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 S-50 is primarily a cavity rustproofing compound it’s also able to prevent corrosion in a multitude of mud traps and water collecting voids. dynax S-50 has been used with superb results to protect voids and cavities in steel boats, vessels, off shore installations and other steel structures subject to severely corrosive atmospheres.
dynax S-50 is designed to protect steel surfaces in extreme conditions. It’s well known that vehicle cavities are subject to a wide-range of corrosive environments, from salt spray to high humidity, heat, fresh water and freezing. The cavity wax chosen must cope with all these variables and continue to provide the necessary protection - maintaining the structural integrity, safety, and value of the vehicle. It’s common for manufacturers of cavity waxes to quote salt-spray results in hours for their cavity waxes and while the salt-spray test is severe it’s been shown that waxes with very good salt-spray performance can rapidly deteriorate when the environment changes, for example after a period of constant salt-spray they swell become bloated and detach from the surface in an atmosphere of high humidity alone. dynax S-50 has been proven to provide outstanding salt-spray protection and continuing protection in changing conditions with no swelling or detachment whatsoever. You’ll see below how dynax S-50 compared with two extremely well known cavity waxes in constant salt spray trials.

The final picture in the series below shows dynax S-50 protected metal is still in exceptional condition.
These standardised test panels have been removed from an ASTM B-117 hot salt spray trial after an extremely aggressive 2000 hours - the rear of the panels show that the steel left unprotected is almost corroded through.
The panel fronts as removed are difficult to asses as corrosion streaks and marks are left as during the test the unprotected panel edges allow corrosion deposits to pour down the vertically positioned panels.
After solvent washing the panel fronts any remaining waxy film is removed, allowing inspection of the underlying surface. Assessment of the product performance is then easy.
If you decide to treat your car or vehicle to additional corrosion treatment it’s important to select a cavity wax that can penetrate into welded flanges seams - these are the areas proven to be the first to corrode - in fact the Swedish Corrosion Institute conducted a thorough investigation into vehicle corrosion by sawing open the bodies of 845 collision-damaged cars manufactured between 1994 and 1997, the corrosion observed in the flanges and seams resulted in the recommendation that even on cars with reasonably good cavity fluid treatment applied at the factory a complementary treatment be used within 3-4 years of manufacture. This investigation also proves, despite popular belief, that modern cars just like classic and vintage ones require after market rust proofing.
dynax S-50 has a high solids content - over 50%, it’s this content that forms the anti-corrosion coating, and whilst other high solids materials don’t penetrate sufficiently dynax-S50 creeps by capillary action deeply into seams, flanges and folded edges, in side-by-side trials dynax S50 has been proven to creep significantly further than other cavity waxes, some with solids contents as low as 25%.
