TSP5 is the hardest powder in the TSP line, and a great choice in cold conditions, both for alpine and cross country. It is loved by servicemen, due to its great durability and dry friction properties. It is made as a powder to make it easier to apply, without sacrificing the great glide properties. For fresh, old or artificial snow. The speed of the iron should be approx. 8-10 sec. on a skating ski. Important to have a good iron to get an efficient melting of the powder. TSP5 can be used as a race powder alone or as a base for top coats. Recommended iron temp: 160°C (320°F).
