Does aluminium bottles react with coatings based on nanotechnology?

I am rather unfamiliar with chemistry, so therefore I hope that you are able to help me.

I am in the process of starting a distributor of nano-based coatings, due to their great beneficial elements.

As a part of the process I am naturally looking for bottles. I do know that the ceramic coatings has to be stored in Aluminum bottles. I would prefer to store all my coatings in aluminum bottles, but I'm uncertain whether or not they will react with the aluminum, and what the reaction will do. 

The coatings are water based, and made on the chemical basis "modified SiO2". The chemical stability is between pH1pH1 and pH13pH13, does that create any difference? I do recon that some of them contain a water-ethanol mixture.

The bottles I am looking at is: Chemical pesticide insecticide agrochemical pharmaceutical metal 100 ml aluminum bottles, stainless steel aluminum and regular aluminium bottles.

I have read some where that it depends on the pH value on my coatings, where they are above 3 or below 9. 
If that's the case, what will happen if it is below 3 or above 9?

My supplier told me that the chemical stability is between pH 1-13, which is close to the whole pH scale. What does this mean?

Please do ask if any further information is required, hope that someone is able to help me. Tried to do some research on my own, but without much chemical knowledge it's tough.

Kind regards,
