ahhh! I just had a flash back.Tried to get TScheidner to tell me what makes that stuff flow and she would't. I believe it is just thinset with something to make it flow ie more water and primer mayber, with more hardener Smells the same. Costs twice as much. T posts blogs all the time at FI.com. She's the head tech guy over at Ardex http://www.flooringinstaller.com/profiles/blogs/ardex-designer-floor Don't call her a guy though.
I gotta old timer tile guy who uses thinset with lots of water to make his own SLC. ahhh crazy
(This was in the late 70's)

Guy at the counter says:
"That's what the guys are using............ Smells the same."
.......ok, back on topic.
