摘要:
Improved article drying compositions which effectively remove water from the surface of non-absorbent articles to be dried, are provided. The solvents used to formulate the additive modified compositions are azeotropic binary mixtures, comprised of isobutanol and trichlorotrifluoroethane; and n-butanol and trichlorotrifluoroethane. The non-volatile additive, dissolved in the binary systems comprises a phosphate ester free acid type. These additives characterized as complex phosphate ester-free acid surfactants of the ethylene oxide type, which are commercially available, are preferred.
