Superhydrophobic and oleophobic

Nice video,


But,

From the coating distributor:

Ultra-Ever Dry is a superhydrophobic (water) and oleophobic (hydrocarbons) coating that will completely repel almost any liquid. Ultra-Ever Dry uses proprietary nanotechnology to coat an object and create a barrier of air on its surface. This barrier repels water, oil and other liquids unlike any coating seen before. The other breakthrough associated with Ultra-Ever Dry is the superior coating adherence and abrasion resistance allowing it to be used in all kinds of applications where durability is required.

See Wetting.

Wetting of different fluids. A shows a fluid with very little wetting, while C shows a fluid with more wetting. A has a large contact angle, and C has a small contact angle. – Wikimedia

However, detergents, soaps, Solvents or high pressure water must be kept away from the surfaces or the coating will fail. And it should not be touched with your bare hands  — to protect the coating and/or your hands?

    That’s remarkable. I don’t even care that it’s virtually a commercial since it’s so fascinating to watch. Thanks for posting.
