Long-lasting soil-repellent finishes for leather

摘要

Lanxess and Japan's Daikin Industries Ltd have jointly developed a water-based anti-soiling system that effectively protects pale-coloured leather surfaces from soiling.The product 'Aquaderm X-Shield' is based on an aqueous polymer dispersion that is applied as a top coat on the leather.Unlike conventional systems,whose soil-repellent substances gradually wear off,the binder system developed by Lanxess and Daikin with PTFE (polytetrafluoroethylene) segments incorporated by polymerisation is firmly anchored on the surface of the leather.
