What about the hydrophobic material that might stick to the surface? As they are hydrophobic, they wont interact with water and hence cleaning them is not possible in case of self cleaning coating too.
Thank you

Can the PERFLUORODECYLTRIMETHOXYSILANE apply on the glass surface, paint and plastic surface?

I have used fluorine based coating with 5% SiOinside the content. The water repellent effect is quite good on the painted surface, but won’t last long. Is that the fluorine is not a good material for chemical bonding to the paint?

Answering to Benny Ho…

yes, there are many products that can be sprayed. a solution of PERFLUORODECYLTRIMETHOXYSILANE in ethanol can be sprayed over any surface, making it superhydrophobic (after drying).

the problem of this technique is that if ther is no chemical reaction between the surface and the PERFLUORODECYLTRIMETHOXYSILANE, the product will wash away after some uses.

for enhacing the reactivity between the surface and the perfluorodecyltrimethoxylane 20 second plasmas treatment is enough…

hope I´m helpfull..

Is there any ready-made product to spray on surfaces?
How to use?

Hi There,
How much less friction is there with water flow over a superhydrohobic coated surface compared to a hydrophilic surface…anyone know? And are there any published tests con firming this? Cheers
