Powder REX NFX 00 SISU White 20g

Powder REX NFX 00 SISU White 20g

Ultra high wear-resistant fluorine-free racing powder, designed specifically for long-distance skiing (ski marathons). The white powder is universal and suitable for use in all conditions. It can be used either as a top layer over an NF paraffin or completely on its own, also as a reinforcing base layer for other NFX powders. The powder contains UHW, i.e. extremely hard and wear-resistant wax particles that ensure durability and repel dirt. This is the first UHW-containing product that can be fixed with a waxing iron, which is only possible due to its powder form. Melting point 140°C, recommended waxing iron temperature at least 180°C (scrape while warm, see usage instructions below). One container contains 20 grams, sufficient for up to 8 pairs of skis.

What is Rex NFX?

In short, revolutionary NFX powders are the fastest fluorine-free ski waxes available. NFX stands for Rex’s fluorine-free racing powders, developed in cooperation with the world’s top ski teams to achieve maximum glide. Instead of fluorinated compounds, micronized Rex Power Polymer blends are used. Each NFX product contains condition-specific hydrophobic additives and N-Kinetic nanoparticles, which can only be blended and used in powder form. When applied to the ski base, these blends form a strong matrix. NFX powders are at the top of glide tests and consistently reach the podium.

Race waxing with NFX powders

Start every waxing with Rex NF SISU base paraffin or standard Rex blue paraffin. This base bonds well with the ski base and improves the wear resistance of subsequent layers. Next, apply a condition-appropriate NF-series racing paraffin. Finally, cover it with the NFX racing powder designed for the same conditions. When waxing for ski marathons or other long distances, the NF paraffin layer can be omitted and the NF SISU base paraffin can be directly topped with NFX 00 SISU powder – either the universal white or the black version for new snow. For best results, use a very hot waxing iron (180–220°C) when applying all NFX powders, even though the melting point is significantly lower. The powder can also be used at temperatures close to its melting point. Apply the powder to the ski base, carefully heat it in, allow it to cool (except SISU and NFX41), scrape off the excess and brush thoroughly with a stiff nylon brush. SISU and NFX41 powders (as well as NF31 paraffin) should be scraped while still warm. Be careful not to damage the ski base with excessive heat! NFX powders do not contain substances harmful to health or the environment, but to avoid inhaling dust, the use of an FFP3-level mask is recommended. One container is sufficient for waxing up to 15 pairs of skis.

NFX or NFX 00 SISU?

There are two types of NFX powders: the familiar numbered color-coded products and the new SISU powders, available in two versions – white and black. Which one should you choose? The decision depends on whether immediate maximum speed or the longest possible glide durability is more important. On shorter distances, standard NFX powders are generally faster. In the second half of longer distances, skis waxed with NFX 00 SISU are often faster due to higher wear resistance. It has also been observed that in cold conditions, NFX 00 SISU powders are usually faster, while in warmer conditions they may be slower than standard NFX powders. However, if the snow is particularly abrasive or dirty in warmer weather, SISU powder may be the better choice. If you only ski marathons, SISU powder is a very sensible option – easy to choose, universal and long-lasting.
