Bilt Hamber Dynax S50 (750ml)

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 provides long-term protection to pre-corroded and corrosion-free surfaces.

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 ultraviolet (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, ot's also able to prevent corrosion in a multitude of mud traps and water collection 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. 

Dynax-S50 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 of for their cavity waxes and while the salt-spray test is severe it's been show 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-S50 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-S50 compared with two extremely well known cavity waxes in constant salt spray trials.

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 flange 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-S50 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%.

How to use:

 

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; very wet surfaces should be pre-treated using Bilt-Hamber Ferrosol.

Dynax-S50 aerosols require no compressor or additional equipment.

Dynax-S50 is also available in 5 litre tubs to 200 litre drums and upwards for spray application, for those without access to professional wax injection equipment Bilt-Hamber Laboratories have developed a superb system enabling Dynax-S50 to be applied at high pressure simply, quickly and without mess. 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.

Dynax-S50 Pack with 60cm cavity injection lance.

Dynax-S50 is tolerant of a broad range of application pressures and will form a coherent film upon application. Dynax-S50 will increase in viscosity at low storage temperatures.

It is recommended to place the container in a room at around 15 degrees C for 24 hours prior to use, particularly when using low pressure equipment for spray application.

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. Never heat aerosol dispensed product. 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.
