TSP8 has a softness and racing formula that makes it perfect in conditions on both sides of the freezing point. The speed of the iron should be approx. 8-10 sec. on a skating ski. It’s important to have a good iron to get an efficient melting of the powder. TSP8 can be used as a race powder alone, but is often used as a base for top coats.Specifications:- Weight: 40 g/1.4 oz.- Iron temp: 180-200°C (356-392°F)
