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.

摘要： The present disclosure provides a degreasing apparatus which may be made at least partially, or substantially, of at least one plastic material, for use with solvents having relatively low boiling points that are chemically compatible with plastic materials, such as 1233zd (1-chloro-3,3,3-trifluoro-propene, CF3CH═CHCl). Plastic degreasing apparatuses may comprise a tank comprising a side wall and a bottom wall, a partition coupled to a lower portion of the tank, dividing the tank into an immersion sump and a vaporizing sump, a heating element located within the vaporizing sump, and a condensing element positioned above the lower portion, wherein at least one of the side wall, the bottom wall, and the partition is made of a plastic material.
