Temperature range from -12°C to -32°C (10°F to -25°F). Recommended iron temp: 155°C (311°F). A new cold hydrocarbon wax for extreme cold conditions, which can perfectly be used alone as a race wax when the air humidity is low. It performs very well on artificial snow and has a great durability. The speed of the iron should be approx. 8-10 sec. on a skating or alpine ski. The wax can be re-heated after cooling to room temperature (10 min) for better durability. Scraping after appr. one minute. Important to have a good iron to get an efficient melting of the wax. Scraping after appr, one minute. In the warmer part of the temperature range, and when high air humidity, Cera F powder, such as FC04X will increase the performance.
