Swix CH4X/CH4 ski wax is a cold hydrocarbon wax designed for extreme cold conditions. The high level of durability that comes with wax of this hardness makes it ideal as a dryslope wax, or particularly rough artificial snow. When air humidity is low CH4 can be used alone, but towards the warmer end of the spectrum with higher humidity, Swix Cera F powder such as FC04X will increase performance. When operating a waxing iron at the recommended temperature of 155°C, ensure that you keep the iron moving over the base at all times as you will very easily be able to burn the ski base at such a high temperature.
The 'Fluor Free' badge on the label signifies Swix's commitment to environmentally friendly and biodegradable products. The company is continuously working on being able to offer fluor free alternatives in each of their wax categories to minimise their impact on the environment.
