Personally, I've never heard of it nor can I find it anywhere on the WEB. BUT, that doesn't mean it doesn't exist. Have the Contractor give you info on the product.
I'll offer some unsolicited words of caution. Do understand that, in general, concrete needs to breath. If you seal it and there really isn't any other way for the concrete to 'breath-off' the moisture in it, you'll end up with blistering (where you've sealed it.) This occurs because the moisture is trying to escape. This is especially problematic where slabs are below grade. Moisture enters from the 'sides' and bottom and the only escape is via the top-side of the slab. When sealing it, well, what would you expect? Assuming the slab is somewhat ABOVE grade, you may be OK.
Also, consider a sealer that has a 'grit' in it. It's for non-skid use. Believe me, you'll be GLAD you used it if any water or moisture ends up on top of the sealer. Of course, it prevents injuries and will probably keep your 'insurance liabilities' to a minimum.
My best to ya and hope this helps.
