Temperature range from +2°C to -6°C. Recommended iron temp. 170 °C: A powder developed for normal winter conditions from around freezing and colder. From the cold side this powder performs well until you have a “suction” feeling in the track, then the FC08X is a better choice. Suggested base waxes are HF07X, HF07BWX or LF07X. The speed of the iron should be approx. 4-6 sec. on a skating or alpine ski. It’s highly recommended to have a good iron when working with powders. The powder should be ironed once.
