The BD line of waxes has been extraordinarily popular and successful. Why change it? The reason is yet another improvement in performance with the BW Additive!
Swix BW Waxes contain solid lubricants. These waxes have proven to work well in old, coarse grained snow, dirty snow and abrasive man-made snow. The snow crystals of old, coarse grained snow have few asperities that can easily yield to ski movement. At low temperatures when the lubricating liquid water layer is poorly developed, the deformation of the snow crystals is slow, which means that the snow is hard and not slippery resulting in higher friction. Dirty snow that contains particles other than ice, cause an increase in friction because the particles have not developed a lubricating layer of water. Man-made snow being made up of ice particles rather than natural snow crystals also can increase friction. All these examples require a lubricating material other than just normal wax. Therefore, under such circumstances, it is beneficial to wax boards and skis with a wax containing a solid lubricate additives.
The BW Additive works well on old, dirty snow because the friction is not only between the snow and base rather a combination of snow and dirt and the base.
Summery
- Swix BW Waxes contain solid lubricants as additives
- Advantages during:
- Course grained snow
- Dirty snow
- Man-made snow
- Dry friction (very cold temperatures)
Characteristics of dry lubricants
- Low friction coefficient
- High lateral strength, low transverse strength. This means that between highly loaded surfaces the lamellar structures of the solid lubricants prevent contact. In the direction of motion the lamellas (layers) shear easily over each other
- Perform well in humid environment
- Good mixing capabilities with waxes
CrossCountySkier.com will soon be introducing this excellent new product range so you can enjoy a faster smoother ride down the mountain.
