Definitions

  • the present invention relates to cleaning compositions capable of both cleansing insulated surfaces which have become defective and contaminated with carbonaceous matter, salts, water and other contaminants, and providing a priming coat for subsequent re-insulation.
  • Such compositions are intended to be employed for instance in the cleansing of rotating electrical machinery in which electrical resistance has been impaired by exposure to adverse conditions, including such machinery in marine service, the compositions also serving to prime the machinery for the re-application of insulating varnish or other coating media.
  • a composition containing a cationic surfactant comprising an organic acid salt of a primary, secondary, tertiary or quatemary amine containing a hydrocarbon moiety of not less than 12 carbon atoms; a hydroxy aromatic acid or ester thereof; and at least one organic solvent.
  • the proportions of the said surfactant to the said hydroxy aromatic acid or ester thereof may vary over a wide range, for instance from percent by weight to 90 percent by weight of the said surfactant to the said hydroxy aromatic acid or ester thereof. Expediently, the proportion of the said surfactant to the said hydroxy aromatic acid or ester thereof may be from 35 percent by weight to 65 percent by weight. It is preferred that the cationic moiety of the surfactant should contain at least two like or unlike amino groups.
  • we provide a method for cleaning a contaminated surface comprising applying to the said surface the composition of this invention and allowing the solvent(s) to volatilize, thereby cleaning the surface and forming a protective film thereon.
  • the preferred method of application is by spraying.
  • An insulating varnish or other coating may then be applied, e.g. by spraying, to the said protective film.
  • a method for cleaning a contaminated surface comprising applying to the said surface components which will react in the presence of organic solvent in situ to form a cationic surfactant comprising an organic acid salt of a primary, secondary, tertiary or quaternary amine containing a hydrocarbon moiety of not less than 12 carbon atoms; a hydroxy aromatic acid or ester thereof; and at least one organic solvent; and allowing the solvent(s) to volatilize thereby cleaning the surface and I forming a protective film thereon.
  • the said surfactant-forming components may be, for instance, the inorganic salt of the corresponding amino compound and an organic acid or a salt thereof.
  • the preferred method of application is by spraying.
  • an insulating varnish or other coating may then be applied, e.g. by spraying, to the said protective film.
  • a method for cleaning a contaminated surface comprising applying to the said surface a cationic surfactant comprising a hydroxy aromatic acid or ester salt of a primary, secondary, tertiary or quaternary amine containing a hydrocarbon moiety of not less than 12 carbon atoms, and at least one organic solvent, and allowing the solvent(s) to volatilize thereby cleaning the surface and forming a protective film thereon.
  • a cationic surfactant comprising a hydroxy aromatic acid or ester salt of a primary, secondary, tertiary or quaternary amine containing a hydrocarbon moiety of not less than 12 carbon atoms, and at least one organic solvent, and allowing the solvent(s) to volatilize thereby cleaning the surface and forming a protective film thereon.
