Abstract

Procedimento per proteggere legno, marmo, laterizi gesso, cemento e materiali simili usati in particolare nell'edilizia, dall'azione di degrado provocata da agenti e inquinanti atmosferici, mediante applicazione sulla superficie di detti materiali di un agente protettivo scelto fra dispersioni acquose di poliuretani fluorurati, la parte fluorurata derivante da unità fluoropolietere, ad elevato peso molecolare medio numerico, almeno ?8000, ed aventi un contenuto in fluoro maggiore di 25% in peso e contenenti nelle loro strutture gruppi ionici idrofili di natura cationica o anionica in cui i gruppi cationici o anionici sono presenti come gruppi laterali rispetto alla catena polimerica poliuretanica.
