Q."Ski wax" is an application of nano product in the field of :

Nanotechnology is best understood not as a single product category but as a horizontal enabling technology that touches almost every industrial sector at once. In the automotive industry it shows up in lightweight construction, paint systems (fillers, base coat and clear coat), catalysts, tyre fillers, sensors, and windscreen/body coatings. In the chemical industry it enables paint-system fillers, nanocomposite-based coating systems, paper impregnation, switchable adhesives and magnetic fluids. In engineering it is used for wear-protection coatings on tools and machines -- including anti-blocking and scratch-resistant coatings on plastic parts -- and for lubricant-free bearings. In the electronic industry it underlies data memory, displays, laser diodes, glass fibres, optical switches, IR-blocking filters, and conductive antistatic coatings. In construction it appears as thermal insulation, flame retardants, surface-functionalised building materials for wood, floors, stone, facades, tiles and roof tiles, facade coatings, and groove mortar. In medicine it enables drug delivery systems, active agents, contrast media, medical rapid tests, prostheses and implants, antimicrobial agents and coatings, and cancer-therapy agents. Beyond these six core sectors, nanotechnology also reaches textiles (surface-processed fabrics, smart clothes), food and drinks (package materials, storage-life sensors, additives, fruit-juice clarifi …
