Superhydrophobic and oleophobic coating

[egneg]

I would like to see how this would work on a boat hull.

$60.00/quart bottom coat and $100.00/quart top coat but they cover 60 square feet.

Should break water adhesion on the hull .... making it slicker than goose grease! Wonder if it would make things waterproof.

wonder what kind of shelf life it has once its open!

[egneg]

I was also wondering if it would be safe to use on electronics and shelf life once open. Maybe they will come out with smaller containers as $160.00 is a bit much. This is brand new stuff and they have been swamped with questions from folks.

Oh Steven, this could be aproduct for the store. Perhaps they would allow you to repackage it!

It is non conductive and safe temps up to 300 degrees

With Xylene being used as the solvent for this I am not sure about electronics - it may be just fine would have to try on an old esc or similar first.

Just wondering if aplying a coat of this to the hull wont make it ultra repelent to the water causing to much lift therefore loosing control of our "small and lightweight" rc boats. Maybe if it is heavy enough 25lbs+ (not an ingeneer), the weight itself of the hull will be more than the repelent force at high speed, keeping the keel in the water. Great for saw but in small race boat just wondering if it will be more detrimenting than an aid tool.

I don't think the displacement will be affected but if there is a significant speed increase you could be right.

As was mentioned on IW by a veteran boat racer, coating the bottom of your boat with a hydrophobic coating or wax may make your racing boat too slippery and reduce control/handling. SAW racing might be a different story, but with SAWs your boat is supposed to be setup to float on air at speed anyway.
I may ordered some of this stuff to try on my hunting boots though. There are two solvents required for cleanup. Xylene for part 1, and acetone for part 2.

If the boat was marginally under control in the first place it might but I don't see how a boat hull that is allowed to air out better and gain some speed will equate to loss of control.

In theory it will be like driving an oil drop over water with minimal adhesion. Techinally it will be suspended on the water unable to break properly water tension (IN THEORY). therefore the hydrodynamic propertys of the hull design will be diminished... At least in theory, many other factors have to be taking into account.

Apples and Oranges - Strakes were designed to help air out a hull along with helping to keep it straight as do the sponsons on a cat or hydro. A drop of oil doesn't have these features so how can they be compared? I think we need to do some serious testing before any judgements can be made either way.
