- The other Fun Fact I know about durometer, from the former head of R&D at
- Kryptonics, is that the hardness of a wheel is highly temperature-sensitive. A
- 10-degree F shift in temperature will radically change the
- performance/handling characteristics of wheels.

- The same goes for skating floor coatings. The properties for the floor
- varies with temperature and humidity. I have noticed two levels of
- grip for floors -- a "static" grip and a "dynamic" or speed grip. The
- current coating at my frequented rink is terrible -- it has a floor
- that has a decent static grip but it is slip and slide at any
- reasonable speed. (The rink is Roller Kingdom in Tyngsboro MA.) This
- terrible "deceptive" property gets worst with lower temps and the rink
- owners only run the heating around sessions. Humidity moderates it --
- the floor gets tighter on humid days unless it starts to sweat in
- which case it is back to slip and slide again. The artistic club is
- using plaster of paris on the floor for more grip. The coating was
- chosen by the rink management because of moisture problems and the
- coating "breathes". The rink is on an old ice skating bed and the
- contract they have with the building owners states that should be able
- to revert to an ice rink again.
