Invention relates to corrosion-inhibiting compositions and the process of using said compositions to protect metal from corrosion. The compositions comprise of sulfonates, a carboxylic-sulfonic acid metal complex, antioxidants, fluorinated copolymers, hydrophobic silanes and siloxane additives and solvent.

Corrosion preventive compositions

A non-aqueous solvent composition and method for cleaning and removing oleaginous materials such as hydraulic fluids from reinforced-fiber composites characterized as a cleaning composition free of ozone depletion materials, having a low vapor pressure, a flash point above 140&#xb0; F., and consists essentially of cyclohexenes, isoparaffinic hydrocarbons, dearomatized hydrocarbons and corrosion inhibitors.

Composition and method for cleaning and removing oleaginous materials from composites

The present invention relates to siloxane compositions having a VOC of about 19 g/l, a flash point above 140&#xb0; F., and a vapor pressure of less than seven millimeters of mercury (7 mm Hg). The siloxane compositions consist essentially of unsubstituted and/or alkylated cyclicsiloxanes having 5 or 6 silicon atoms, an alkylated cyclicsiloxane having 3 or 4 silicon atoms, a linear alkylated siloxane fluid, at least one alkylene glycol alkylether and an alkylene glycol having at least six carbon atoms.

Siloxane compositions comprising an alkylated cyclosiloxane and linear alkylated siloxane mixture

The present invention relates to non-volatile organic compositions having a VOC of about zero, a flash point above 140&#xb0; F., and a vapor pressure of less than seven millimeters of mercury (7 mm Hg). The non-volatile organic compositions comprise an alkylated cyclicsiloxane having 5 to 8 repeating siloxane units, an alkylated cyclicsiloxane having 3 or 4 repeating siloxane units, and at least one glycol alkyl ether.

Siloxane solvent compositions

The invention relates to an oleaginous corrosion-inhibiting composition, and the use of said composition to protect metal from corrosion. The composition comprises, in parts by weight, from about 20 to 60 parts of lubricating oil, 10 to 40 parts of organic solvent, 20 to 60 parts of corrosion-inhibitor consisting of a sulfonic acid-carboxylic acid metal complex or a mixture of said metal complex with a small but effective amount of an oil soluble alkyl phosphate, from 0.1 to 2.0 parts of an oil soluble antioxidant, from 0.1 to 5.0 parts of a water-displacing compound and from 0.0 to 1.0 part of a metal deactivator.
