PRECIS DE LA DIVULGATION:
L'invention propose une composition comprenant en poids 30
à 69% de 1,1,1,3,3-pentafluorobutane (F365 mfc), 30 à 60% de
chlorure de méthylène et 1 à 10% de méthanol. Ces trois
composés forment un azéotrope positif (Eb. = 32,1°C à la
pression normale). La composition, éventuellement
stabilisée, peut être utilisée pour le nettoyage et/ou le
séchage de surfaces solides, en particulier pour le
défluxage des circuits imprimés et pour le dégraissage de
pièces mécaniques.
