Just a plain water spill will make a track section twice as slippery as it is dry. The recommended 3% WaterWetter added to the coolant water doesn’t make it any more slippery, so it’s approved for racing applications here in the US. Check with your track and racing organization, I’ll bet it’s approved for use. Silkolene Pro-Cool, is formulated with propylene glycol that is less toxic, and consequently environmentally more friendly than ethylene glycol installed at the factory by most manufacturers. Even though propylene glycol has a higher boiling point than ethylene glycol, when mixed with water it is less effective in both removing heat from your engine and transferring it to your radiator. So, it seems that the only logic for using it is to reduce the likelyhood of coolant discharge to racetracks, not for reducing operating temperatures. Both ethylene and propylene glycols are slippery, and hard to clean off the track since they doesn’t evaporate quickly like water. Most racing organizations ban their use.
