How do Pure Fluoros Stick to Ski Bases?

How do topcoats stick to skis? They don't stick to anything so why would they stick to ski bases? My best guess is the super secret stuff that topcoats are made of get heated into the top layer of whatever wax there is on the skis. Some nerdy guy with a Ph.D (and top level skier) once guessed that fluoros bonded to the base via some mode of Van der Waal interaction. He also conceded that he had no other explanation. Really?
