Film protection and hygiene for shoes and textiles have a long tradition. Whereas in the past, fluorocarbon finishes were predominantly used, newer nano-coatings use fluorine-free (PFC-free, C0) or modified silicon dioxide technologies as sealants. These are achieved by spray-on or wash-in formulations for the washing machine. Strong and sustainable stain protection is achieved on fabric shoes such as trainers, lace-up shoes, chucks / converse trainers, canvas shoes, boots, moon boots, sports shoes, running shoes, slippers and leather materials such as leather boots, Derby or Oxford shoes, saddles, sofas or car seats. Nano sealants are also used for permanent anti-microbial odour control. Odour-forming bacteria are killed off by the invisible coating and provide a lasting freshness effect for the hygienic finish of sports equipment, sandals, sneakers and sneakers. Functional clothing such as rain jackets, outdoor clothing (hiking boots, trousers and jackets), work clothing (chemical and oil repellency) can be permanently treated with the DIY process in case of loss of function. Upholstered furniture or seat cushions can be protected against stains by permanent and environmentally friendly surface protection.
