If it's solvent based, by definition it can't be 100% solids. Solvents evaporate, a 100% epoxy has virtually nothing to evaporate - hence no solvents or water included.
The 40 mil total is good, if it's a quality coating it's very good, but in this case it's kind of confusing. That's a lot of epoxy or urethane! Our system is usually 21 - 29 mils thick, and we're at the high end of residential and even shop applications, probably the thickest DIY product on this forum at least. Maybe they're including the thickness of the flakes? That's a bit unusual, but if you have a 100% solids product that has solvent content I guess you can do anything.
Also generally the clear coats aren't near than much thicker than the primer and base coats. Just 10 mils base with 30 mils clear is clearly unusual.
What kind of prep work - grinding? And no primer coat? Hmmm...
BTW, "Industrial" is pretty much meaningless. Find out exactly what facilities use the products. Larger companies often have their own labs and techs test and evaluate coatings and often allow their names to be used in the manufacturer's marketing materials (sadly other companies forbid endorsements).
Ask (demand) for a detailed list of the exact products you're going to be getting, and the associated MSDS info, then post it. We have a few pro installers who will be able to figure it out for you better than I can.
