Less than 1 micron coating on steel.

2000

I am doing a thesis work on how to prevent ugly stains from fingerprints on brushed stainless steel surfaces.

One way that is already used is to put a transparent coating on the surface, these coatings are quite thick and therefore changes the appearance of the surface. I would like to find a thinner coating, 1 micron or less, that is permanent, resistant to moist and is washable. Some kind of dip or spray method to apply the coating is preferable.

Is there anyone who can tell me were to find such a coating?

Is it possible to make a thick layer of chromium oxide instead of a coating, it should in that case be at least 0.3 microns thick.

Dear Gustav:

Thin films are achievable using air dry lacquers.

There are several coating by physical vapor deposition that have wonderful properties.

They are affordable in large batches. A semi local company might do a part or two for a mention in your thesis.
