The basic substance of the sustainable ski wax is indigo, the oldest known stable blue plant dye. One isomer of the commercially available indigo mixtures, E-Indigo, is ecologically and hygienically harmless and fits in the concept of the circular economy. This patented innovation as a lubricant on ice, snow and water can be experimentally proven to form a supra-molecular, self-organized, electrically conductive, hard, abrasion-resistant, hydrophobic sliding surface with self-healing properties.
Substitute for banned fluorinated waxes:
E-Indigo is a substitute for the high-priced fluorinated high-performance waxes, which will be banned by the FIS (Fédération Internationale de Ski) as environmentally harmful from the 2020/21 winter season.
Practical experience as a ski wax replacement over 3 winters with many test persons and numerous field tests have shown the potential of E-Indigo as a high-performance lubricant. Important parameters seem to be the degree of purity of E-Indigo and its application-related microstructure.
Due to the specific chemical bonds, indigo molecules can form clusters of different sizes with platelet structures at the nanometer level. In combination with suitable microstructures, superhydrophobic surfaces can be expected.
E-Indigo clusters are also easily miscible with ski waxes and polyethylene ski bases and form relatively strong bonds. These indigo clusters thus give the ski base or wax a greater hardness, increase the gliding properties, and reduce abrasion. Applications in other areas with sliding surfaces can be expected due to the special molecular indigo properties.
To minimize dynamic friction, an optimum E-Indigo coating on the sliding surface is necessary, which requires in-depth knowledge of the surface structure and an appropriately adapted application.
The aim of a possible collaboration is to develop an evidence-based, competitive high-quality product in various fields of application with minimal impact on health and environment. The potential of the diverse and rather exclusive properties of E-Indigo for bionic-analogue, low-friction, hydrophobic, abrasion-resistant sliding surfaces is given according to the molecular characteristics.
The granting of licenses will be negotiated based on achieved results.
The organization of the cooperation can be taken over by the Swiss company. The necessary know-how is based on many years of experience in self-implemented and participation in development projects.
