Powder REX NFX 41 Green/Pink old snow -8…-20°C 20g

Powder REX NFX 41 Green/Pink old snow -8…-20°C 20g

Fluorine-free racing powder specifically designed for old, coarse-grained snow, and also suitable for artificial snow at all temperatures. It should also be used in extreme cold when blue waxes are no longer sufficiently abrasion-resistant: -8…-20°C. The powder contains UHW (ultra hard wear-resistant) components, which provide exceptional durability and repel dirt. Unlike, for example, SISU powders that also include UHW additives, NFX41 additionally contains compounds designed for wet snow. Melting point 140°C; recommended waxing iron temperature at least 180°C (see usage instructions below). One container is sufficient for waxing up to 15 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, they use micronized Rex Power Polymer blends. 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 consistently rank at the top of glide tests and regularly 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. Take care 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 holds approximately 20 grams of powder, 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 long-lasting glide is more important. On shorter distances, standard NFX powders are generally faster. In the latter half of longer distances, skis waxed with NFX 00 SISU tend to be faster due to their higher wear resistance. It has also been observed that in cold conditions, NFX 00 SISU powders are often faster, while in warmer conditions they may be slower than standard NFX powders. However, if the snow is especially abrasive or dirty in warmer weather, SISU powder may still be the better choice. For marathon-only racing, SISU powder is a very sensible option – easy to choose, versatile, and long-lasting in performance.
