Abstract

Agente per la riduzione della resistenza aerodinamica opposta a corpi solidi (aeromobili) in movimento in un fluido aeriforme (aria) costituito da almeno un composto, preferibilmente polimerico, avente un contenuto di fluoro e/o silicio almeno uguale al 15% in peso circa, un peso molecolare medio compreso tra 500 e 500.000, eventualmente veicolato in acqua e/o in un mezzo organico, ed un angolo di contatto con acqua (misurato secondo la norma ATICELCA 21-72) almeno pari a 80°.
