Now that sounds cool. One thing I have to remember myself, you can never say, "this is the way it is" as technology is always evolving adn we have to keep up, or an oposition will pass us by. That's what I have spent years teaching others, I better listen to myself more.

OK, this is what I know. Firstly, the solvent, which can be organo, mineral of water based, does one basic job. It's there to get the paint from the tin to the job. So the solvent it's self is not actually what makes a paint what it dries out to be.
A paint is essentialy a "protective coating" that does a specific job. Undercoats have pigments added, but not essential to the paints main purpose. Undercoats are formulated mainly for adhesion and filling.
Top coats use pigments that ARE essential to the paints main purpose. These paints are formulated for the purpose of finish, colour and protection.
The formula's of each type may be different, but the essential simularity is that they have a "Binding Agent" to hold all the ingredients together in a suspension till the binder hardens. The binder works by a chemical reaction. Essentially it is kinda like a two pot mixture that once two molicule parts come together, they react and harden. The solvent keeps these two parts apart till it reaches the surfacing being painted. The next job is the finish as the paint dries and hardens. Organo solvents and Mineral based solvents have in the past, been the most supperior in getting a high gloss finish. This is in how the solvent evaporates away from the paint.

(Without getting to far of track here, a "Real" two pot paint, often doesn't have as much solvent, because the keeping of molicules apart is not an essential part of the solvents purpose. Epoxy based paints often have no solvents at all.)

So, the goal for these paint makers is to get a binder that acts like a resin and will go very hard, will have good colour and gloss once the solvent has evaporated away, and of course, use water as the solvent. I don't see it as impossible, jut someone needs to invent the technology and by that website, it maybe that someone has.

By the way, I think I have heard of a water based epoxy, but I have never used it.
