Solvent and water based dressing

[zaidgreat]

What are your reasons for choosing a solvent based silicone dressing rather than a water based silicone dressing? vice versa....
After browsing thru some MSDS sheets on both, majority of the dressing uses siloxanes, silicones, polydimethylsiloxanes etc.
The major difference would be the carrying agent, either petroleum distillates or water.

Re: Solvent and water based dressing

the difference is pretty simple..you would want to use a solvent based dressing on exterior trim for durability, being that it will last through a few washes and rain..water based dressing will just come right off when it rains or when you wash..and on that note, water based dressing is great for interiors..non greasy, great shine. a solvent based dressing on the interior may still be greasy after dry and its just not really a good idea for interiors. but that doesnt mean you cant use it..vise versa for water based dressings on exterior..experiment with both and see what you like

The silicone free is likely to be used around paint shops, where avoiding silicone contamination on the surfaces to be painted is key.

Tyre Dressings

As every Concours d'elegance participant knows, dull or weathered tyres spoil the look of an otherwise immaculate vehicle. Matte black tyres with a natural sheen are quite simply the final touch to an otherwise perfectly prepared vehicle.

Detailing relies on the correct preparation procedures and the correct methodology to obtain pristine results. For any tyre protect ant to work well on rubber it must be applied to a clean surface. A rubber cleaner (Menzerna Wheel Surface and Tyre Cleaner pH 7.5 or 3M Tyre & Wheel Cleaner -39036) will remove old dressing, any dead rubber and properly prepare your tyre for the application of a protective product. The porous nature of rubber and polymers attracts dirt, dust, and brake dust and road grime.

Water- based vs. Solvent-based Tyre Protection

The difference between water and solvent based is in the carrier system used. Solvent based products use a hydrocarbon silicone to suspend the product. When you apply it, the solvent evaporates leaving the dressing's active ingredients (silicone oil) behind; this type of silicone leaves a high gloss shine and will repel water longer but it is non-biodegradable. Most high gloss products are based upon (DMS) solvents. Water-based dressings (usually a milky-white liquid) use a combination of natural oils and polymers to offer a non-greasy, satin finish

For vehicles fitted with ceramic brakes and / or pads; products that contain DMS solvents are not recommended as it can contaminate the pads and render them ineffective

Silicone [: Polydimethylsiloxane (PDMS) belong to a group of polymeric organ silicon compounds which are commonly referred to as silicones.] CAS number - 63148-62-9

a) Water-based silicone dressings - usually a milky-white liquid that don’t contain petroleum distillate solvents that can harm rubber and/or vinyl over time; water-based dressings use a combination of natural oils and polymers that coat and bond to offer a non-greasy, satin finish (Zaino Z-16 Perfect Tyre Gloss or Swisswax Pneu) Some of these products also contain ultra violet radiation (UVR) blocking agents to help keep tyres from cracking, fading and hardening. Most, if not all water-based dressings are biodegradable whereas solvent- based silicone is not.


b) Solvent-based silicone dressings - usually a clear greasy liquid, Dimethalsiloxane (DMS) that contain petroleum solvents as a cleaning agent. These penetrating-type silicone oils form a flexible protective shield that prevents penetration of moisture and dirt. Most silicone dressings, although very durable, leave a never-dry high gloss film, they remove the elasticity from vinyl, rubber and paint; causing them to evaporate out of the substrate, leaving behind a dry inflexible surface.

Most high gloss products are based upon DMS silicone oil, the difference between water and solvent based is in the carrier system used. Solvent based products use a hydrocarbon silicone to suspend the product. When you apply it, the solvent evaporates leaving the dressing's active ingredients (Silicone oil) behind; solvent-based silicone is not environmentally friendly / biodegradable

Many tyre manufacturers (BF Goodrich, Goodyear, Michelin, Pirelli, etc) have issued technical service bulletins advising against the use of tyre dressings containing Dimethalsiloxane (DMS) a petroleum distillate solvent. This type of solvent will dissolve away the protective waxes and can actually aggressively compromise the sidewall. In the event of warranty sidewall failure, one of the first things tyre manufacturers look for is evidence of the use of these types of products. When found, this is often the cause for not warranting the tyre’s sidewall failure.

The big three auto companies (Ford, General Motors and Chrysler) have issued advisories or technical bulletins to their dealers to not use heavy petroleum distillate-dimethal silicone oil dressings for another reason; paint and wheel surface staining. Auto companies have found that it is next to impossible to remove the stains, In some cases, even repainting the part doesn’t' t work as the stain comes back through the new paint, requiring the part to be replaced. Most factory styled wheels are coated with a clear coat type of coating. Some are more porous than others and use of an incorrect dressing may stain them the same as the body parts.

Re: Solvent and water based dressing

Solvent based dressings:

higher durability, cost more, exterior only, cant use them on motors, higher gloss levels

Water base dressings:

less durability, dilutable, interior/exterior, motor friendly, lower gloss

The OP was inquiring about water-based silicone dressing and solvent-based silicone dressing. Both have silicone.


TOGWT, very nice post and great article. Thank you for that info.

Re: Solvent and water based dressing

Maybe i should stop using megs ASD for my tires
But i have come across water based dressing that contains DMS

TOGWT, what's your opinion on that?
