A stripping composition and method for removing a coating, such as a water-based or oil-based paint or stain, from a surface without requiring the use of methylene chloride. The stripping composition preferably comprises at least one ether, at least one ester, at least one amine, at least one alcohol, and at least one glycoside and does not contain any methylene chloride. Preferred ingredients comprise 1,3 dioxolane, acetic acid methyl ester or a carbonate ester or both, MEA (2-aminoethanol), benzene methanol, an alkyl polyglucoside, and methylcellulose. The stripping composition is applied to a coating for a period of time between 5-10 minutes for most water and oil-based coatings and 20-90 minutes for most epoxy coatings to effectively remove at least 80% and preferably at least 90% of the coating.

The present disclosure provides minimum-boiling, homogeneous azeotropic and azeotrope-like compositions of 1,2,2-trifluoro-1-trifluoromethylcyclobutane (“TFMCB”) with each of ethanol, n-pentane, cyclopentane, trans-1,2-dichloroethylene, and perfluoro(2-methyl-3-pentanone).

A method is provided for removing a residue from a surface. The method includes steps of applying a cleaning medium to the surface containing the residue. The cleaning medium comprises up to 100 wt. % of at least a solvent. Allowing the cleaning medium to be in contact with the residue for at least 5 seconds to swell/dissolve the residue for removing the residue from the surface. At least 50 wt. % of the residue and the cleaning medium are removed from the surface by wiping the surface with a shear force. The residue contains a sulfonated polymer having an ion exchange capacity (IEC) of greater than 0.5 meq/g. The sulfonated polymer can kill >90% of microbes coming in contact with the sulfonated polymer in less than 30 min.

Described herein are solvents and co-solvents comprising anhydromevalonolactone (aMVL) and various industrial applications for such solvents. aMVL has a number of advantageous properties for use in solvent, including high boiling point, low melting point, low viscosity, non-flammability, water solubility, exceptionally low volatility, and excellent solvation capability. Exemplary industrial applications for solvents comprising aMVL include polymer manufacturing, polymer recycling, mold production, fiber production, membrane manufacturing, thermosetting paint manufacturing, coating manufacturing, coating removal, paint strippers, cleaning products, degreasing products, nitrile synthesis, alkylation, production of syngas, carbon-carbon cross-coupling reactions, metal organic framework synthesis, halogenation reactions, formation of pharmaceuticals, formation of fungicides and/or herbicides, seed treatment products, bioregulators, and electrolytes in batteries or capacitors.

A composition suitable for cleaning hard surfaces comprising a natural oil solvent and a natural oil thickener is provided.

The present disclosure provides minimum-boiling, homogeneous azeotropic and azeotrope-like compositions of 1,2,2-trifluoro-1-trifluoromethylcyclobutane (“TFMCB”) with each of ethanol, n-pentane, cyclopentane, trans-1,2-dichloroethylene, and perfluoro(2-methyl-3-pentanone).

The present disclosure is directed to a method of chemically stripping a surface. The method comprises applying a sealant to at least a portion of a surface of an object, the surface comprising a coating and one or more ingression points, the sealant filling the one or more ingression points to form a sealed surface. The method further comprises applying a stripping agent to the sealed surface to remove at least a portion of the coating to form a stripped surface.

A composition for paint removal and methods of making and of using the composition are provided. The paint remover composition comprises a component selected from the group consisting of THF, toluene, acetone, DMSO, dioxalane, 1,2 trans dichloroethylene, and a combination thereof.

Coating installations are provided that include storage tanks for an aqueous base component and a non-aqueous hardener component, circulation lines for the components from the respective storage tanks, a mixer and an entrance to the mixer with a connection between each circulating line and the entrance to the mixer, and a release valve for the non-aqueous hardener component. The coating installation downstream of the non-aqueous hardener release valve is filled with a non-aqueous solvent composition comprising 0 to 10 wt. % of N-alkyl pyrrolidone, 0 to 5 wt. % of dimethyl sulfoxide, 10 to 50 wt. % of γ-butyrolactone, 10 to 50 wt. % of at least one monoalcohol, 10 to 60 wt. % of at least one organic solvent inert towards isocyanate groups, other than γ-butyrolactone, other than N-alkyl pyrrolidone, and consisting of carbon, hydrogen, oxygen and, optionally, nitrogen, and 0 to 10 wt. % of at least one additive.

The present disclosure provides minimum-boiling, homogeneous azeotropic and azeotrope-like compositions of 1,2,2-trifluoro-1-trifluoromethylcyclobutane (“TFMCB”) with each of ethanol, n-pentane, cyclopentane, trans-1,2-dichloroethylene, and perfluoro(2-methyl-3-pentanone).
