Integrated manufacturing of REciclable multi-material COmposites for the TRANSport sector

The invention relates to a fluorinated, alkoxysilyl-functional polymer, obtainable by a method comprising the steps of: a) reacting an OH-functional (per)fluoropolyether (PFPE) with a polyisocyanate A under urethane formation reaction conditions, to obtain an isocyanate-functional intermediate B, b) reacting intermediate B with a secondary, alkoxysilyl-functional monoamine C, to obtain the alkoxysilyl-functional polymer. The polymer can be used as an additive in preparation of a coating with easy-clean, anti-stain and anti-scratch properties, which can advantageously be used for coating various substrates in consumer electronics or automotive applications such as glass, metal, metal alloy, anodized substrates, plastics, composite etc.
