Information on Fluorinated Waxes – FasterSkier.com (2024)

There are three main types of glide waxes used in ski racing.They are hydrocarbon waxes, fluorinated hydrocarbon waxes, and fluorocarbon overlays.Hydrocarbon waxes (System3) are simple paraffin waxes that have varying amounts of oils and synthetic hardeners in them which determine their hardness and what conditions they might be best suited for.Fluorocarbon overlays (JetStream and HelX) are the most expensive sprays, powders, and blocks.These products do not penetrate the base the way hydrocarbon waxes do and are also more challenging to work with.One quirk about Fluorocarbon waxes is that they do not “like” hydrocarbon waxes (think oil and water).Fluorinated hydrocarbons (Dibloc LF and HF) are the link between them.They are a hybrid between the two types (hence the name Toko Dibloc).A fluorinated hydrocarbon is not simply a block of wax containing a mix of a hydrocarbon and a fluorocarbon wax.The combination is actually at the molecular level.

The chart on the left shows a hydrocarbon molecule on the left and afluorocarbon molecule on the right.The molecules can be combined forming a fluorinated hydrocarbon molecule which is shown at the bottom.

Additionally, the respective lengths of the hydrocarbon part and the fluorocarbon part can be varied which changes the properties of the resulting fluorinated hydrocarbon wax.Fluorinated hydrocarbons with longer fluorocarbon parts are more expensive and also more “potent” than those withshorter fluorocarbon parts.This is illustrated in the graphic below on the left.The uppertype shown has a long fluorocarbon chain on the left coupled with a shorter hydrocarbon chain on the right forming a fluorinated hydrocarbon molecule that would be moreexpensive and also more potent.The lower one has shorter fluorocarbon andlonger hydrocarbon parts resulting in a less expensive and less potent fluorinated hydrocarbon molecule.What can you learn from this?When a wax company representative tries to fill your head with stories about what a “high percentage of fluorine” his brand contains, you can probably assume that they are using the cheap and less potent type of fluorinated hydrocarbon.How to cut through the rhetoric?I recommend skiing on the products that seem to perform well and not to base decisions on talk.

Here are some other noteworthy characteristics of fluorinated hydrocarbon waxes:

1.They are generally more resistant to dirt than hydrocarbons.Of course any soft wax contains more oil than a harder wax and would thus be worse against dirt, but given a similar hardness, the HF waxes are far more dirt resistant than hydrocarbon waxes.

2.They are also more durable than hydrocarbon waxes.Given the same hardness, an HF wax is more durable than a hydrocarbon wax.

3.They are more hydrophobic.Given the same hardness (soft waxes are generally more hydrophobic than hard waxes), an HF wax is better in wet conditions than a hydrocarbon wax.

4.Generally speaking, the harder fluorinated waxes such as HF Blue contain less fluorine in them than the softer ones such as HF Yellow.The harder waxes also contain synthetic additives which make them better in the cold which the softer waxes do not contain.Despite it containing fluorine, HF Blue is not close to as fast when the snow is wet as HF Yellow. HF Blue is specifically formulated to perform in the cold.

5.In the Toko line, given the proper “color” for the condition, the HF wax is generally faster than the hydrocarbon wax.One thing that people seem to overlook is that fluorine is not just good in wet conditions.Fluorinated hydrocarbon waxes are simply very slippery far so more than hydrocarbon waxes.Hold one of each in your hand (of similar hardness, let’s say Red) and rub your thumb over them. The HF wax feels more like soap (and slipperier) and the hydrocarbon wax feels more like wax.One factor in determining whether a wax is fast or not is simply “slipperiness”.The HF waxes are slipperier than the hydrocarbon waxes.

6.There is another reason that we use HF waxes constantly besides them being faster in general.HF waxes are the idea platform to put a fluorocarbon overlay on.Pure fluorocarbons (overlays such as HelX and JetStream) do not “like” hydrocarbons.They try to get “away” from them in any way that they can in a fashion similar to when two positive sides of a magnet come together or when oil and waterare attempted to be mixed.However, the HF wax bonds well to a base (and to hydrocarbon waxes) and fluorocarbons bond far better to HF waxes.It is also worthwhile to note that when a ski is waxed with an HF wax, the molecules align themselves such that the hydrocarbon part angles down toward the ski and the fluorinated part angles up away from the ski.For this reason, when a fluorocarbon overlay is applied over an HF wax, it is almost entirely on the fluorocarbon part of the molecule.The picture to the left illustrates this.The squares represent the hydrocarbon part of the HF molecule and the small circles the fluorinated part of the HF molecule.The big circles represent the fluorocarbon overlay that is being applied.The ski base is represented by the entire big rectangle.Hopefully this chart helps illustrate this truth.The bottom line is that when a fluorocarbon is applied over an HF wax, the fluorocarbon wax job will last far longer than when it is applied over a hydrocarbon.Obviously when using an LF wax, the durability is somewhere between the two extremes.

So, we use HF waxes because they are faster in general and also so our fluorocarbon overlay performs for us for a longer period of time.

Field Report from CXC at the SuperTour

With three races in less than 48 hours at the Michigan Tech SuperTour, having fast skis and good was important — we really wanted to avoid unnecessary energy expenditure. We tested Friday morning and afternoon, Saturday morning and afternoon, and Sunday morning to find the best skis possible for the CXC Team.

All three days, we based with an HF Blue/Moly mix and powdered with Jetstream Blue. Friday’s sprint was at 3pm, and the tracks were glazing a bit — there’d also been a little bit of freezing rain on Thursday afternoon that got groomed in. We ended up waxing a bit warmer than we’d assumed we would for kick — various combinations of Violet, Red and Yellow, depending on the skier’s needs.

For Saturday’s 5/10 classic race, we found the Red Bloc was running really well for glide, and Violet and Red with some Blue cover worked well for kick. A few inches of snow fell before the race on Sunday, and HelX Blue was ridiculously good. Ridiculous. We ended up with three wins (Maria Stuber 5km classic, Garrott Kuzzy 15km skate, Caitlin Compton 10km skate), seven top-threes and 13 top-sixes (SuperTour paying) for the weekend.

Thanks to the Michigan Tech organizing crew for the awesome races and facilities!

Evelyn Dong enroute to winning the Boulder MT Tour

The Toko wax tip for the Boulder MT Tour held up well. Here is a link to a report on the wax tip put out the day before the event. Key was stiffer skis (glide well on icy snow and also stay cleaner than soft skis) with a fine structure. The LF Moly, HF Blue, JetStream Blue with Blue Structurite was great despite the warmer temperatures.

FAQs

Why is fluorocarbon wax banned? ›

In some cases these waxes contain chemicals PFAS (perfluoroalkyl substances) like PFOA (perfluorooctanoic acid). Those byproducts are the cause of the health and environmental concerns related to waxing. Fluorinated chemicals are a growing global concern, ski wax is merely a drop in the bucket.

When should I use high fluoro wax? ›

Fluorinated waxes are particularly hydrophobic—they shed water more quickly and are best suited to wet-snow environments. If the snow is very wet, meaning it packs down into a great snowball, a high-fluoro wax will provide the best glide and acceleration.

What is fluor in ski wax? ›

They refer to waxes that are infused with perfluorinated chemicals. Fluorinated waxes had been commonly used for their superior ability to repel moisture, dirt, and oil from ski bases to achieve a faster ski. Although effective, fluoros are harmful.

Is fluoro wax faster? ›

While fluorocarbon is used in the most expensive waxes, do not fall into the trap of expecting more expense to always be faster. Fluorocarbon is a hydrophobic material to repel moisture. In low humidity or low moisture, a highly fluorinated wax may reduce speed as it essentially increases dry friction.

What can I do with old fluoro ski wax? ›

I.e. Take the fluorinated materials and move them far away from any source where they may be hazardous. 3 Methods are outlined in the interim guidance for destruction and disposal: incineration, Landfills, and Underground Injection.

Why is fluorocarbon bad? ›

Because of the rigidity of fluorocarbon, the angles imposed on a line by various knots weaken the line regardless of whether you wet it or not. Add to this the impact from usage and strain from catching fish, and fluorocarbon can break down at critical points such as during the hookset and while fighting a fish.

What is the difference between LF and HF ski wax? ›

High Fluorocarbon (HF) – These are generally the most expensive waxes but offer strong gliding in wet snow. They are also most effective on wet man-made snow or snow that is dirty. Low Fluorocarbon (LF) – A LF wax has less fluorocarbons than HF or FC but more than CF waxes.

What wax is best for back wax? ›

Hard Wax. This is one of the most effective waxes out there for your back. Hard wax is a warm, thick, sticky type of wax that adheres to the hair follicle with ease.

Why graphite in ski wax? ›

The lamellar structure of graphite (meaning comprised of layers) helps repel dirt which can have a big impact on the performance of your skis over the course of a race.

What do ski wax colors mean? ›

White is the coldest wax Fast Wax makes. Teal is good from 0-20 F. Blue is good from 10 -30F. Red is good from 20-40F. Yellow is good from 30-50F.

Is candle wax the same as ski wax? ›

By the way, if you're wondering about any absolute no-go: You should never use regular candle wax for waxing your cross-country or skating skis. After all, you can never be sure which fragrances and dyes they contain and how well your ski can handle these additives.

Why is fluoro wax banned? ›

The fluor wax ban marks a significant change in the landscape of competitive skiing. It signifies a commitment to the well-being of athletes and the preservation of our natural surroundings, as fluorine waxes have been linked to health concerns and environmental damage.

When to use high fluoro wax? ›

It's common knowledge that high fluoro waxes usually work best in high humidity or wet snow conditions...but there can be exceptions to this rule.

What is the best ski wax for rain? ›

SkiGo HF Red works great as a cover wax or alone in varying wet conditions right around or below freezing. Guru Red can work as a cover or alone in falling, fresh snow, or snow that is rapidly gaining moisture. VR70 is often used alone as a just before klister solution.

Is fluorocarbon harmful? ›

Health Hazard Summary: The most common effect of overexposure to fluorocarbons is irritation of the skin. Fluorocarbons can also affect your nervous system, causing symptoms similar to drunkenness.

Are fluorocarbons banned? ›

Due to international agreements like the Montreal Protocol, the use of many harmful fluorocarbons has been discontinued.

What is the ski wax controversy? ›

Interestingly, PFAS-containing waxes were banned by the International Ski and Snowboard Federation at the start of the 2023 – 2024 season. Norwegian Olympic silver medallist Ragnhild Mowinckel was disqualified last October for competing with fluorinated wax.

Can you fish with fluorocarbon? ›

The use of fluorocarbon has grown tremendously in the past 10 years to now become the most popular line in the bass fishing market. The use of fluorocarbon started as a leader material to be used in combination with braided lines.
