Abstract

Materiale permeabile è il gas dotato di fori continui che lo attraversano, in cui l'interno dei fori è rivestito con il prodotto di reazione di a) un estere di alcole perfluoroalchilico con un acido carbossilico polibasico contenente funzioni ossidriliche, e b) una melammina-formaldeide, urea-formaldeide, oppure formaldeide modificata con glicole. Il materiale è oleofobo ed è utile in applicazioni alla filtrazione ed in indumenti.
