A coating material for a gas barrier includes polycarboxylic acid, a polyamine compound, a polyvalent metal compound, and a base, in which (molar number of —COO— groups included in the polycarboxylic acid)/(molar number of amino groups included in the polyamine compound)=100/20 to 100/90.

The present invention introduces natural and environmentally acceptable (friendly) chemical compositions for fire-fighting liquids and additives, as well as additives for enhanced oil recovery, oil & gas operation facilities and ships, oil refineries and petrochemical industry, drilling and drilling operations, corrosion protection, de-scaling and scaling prevention, cleaning of raw wool, cotton, textile and fabrics, general industrial cleaning and paint/coating removal, leather, fur and skin industries, sewage and effluent treatment, agriculture, meat, fish and poultry industries, olive oil, vegetable oils, and fruit juice industries, health and beauty and pharmaceutical industries, microbial control and insecticide/biocide, soil remediation, and heat and energy conducting fluids.

The present disclosure provides a composition for cleaning or stripping a material from a substrate. The composition includes a primary solvent and a co-solvent. The co-solvent includes one or more caprolactam-derived solvents.

A composition includes a first solvent selected from methyl acetate, dimethyl carbonate, acetone, or a combination thereof, a second solvent selected from thiophene, 1,3-dioxolane, thioacetic acid, or a combination thereof, and, optionally, a third solvent selected from dimethyl sulfoxide, methyl glyoxal, propylene carbonate, gamma butyrolactone, ethylene carbonate, 2-chloro-1-propanol, methanol, ethanol, ethylene glycol, propylene glycol, 1-propanol, 2-propanol, or a combination thereof. The respective amounts of each solvent are further described herein, and the total amounts of the first solvent, the second solvent, and the third solvent sum to at least 90 volume percent of the total volume of the composition. The composition can be particularly useful for removal of a coating from a surface. Accordingly, a method of removing a coating from a surface is also disclosed.

Disclosed herein are a solvent composition and methods of using the solvent composition. The solvent composition includes at least 80 wt. % of trans-1,2-dichloroetheylene (t-DCE), and 0.1 to 20 wt. % of at least one organic compound. The organic compound may be a hydrocarbon and/or an oxygenated solvent. The solvent composition may be used to clean a surface by contacting the surface with the composition to dissolve a contaminant on the surface. The composition may be used to remove a coating from a surface of a substrate by contacting the surface with the solvent composition to dissolve the coating and removing the composition containing the coating from the surface. The composition may also be used to deposit material on a substrate by dissolving the material in the solvent composition, applying the composition containing the material onto the substrate, and evaporating the composition from the substrate.

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.

Disclosed are antimicrobial sacrificial floor coatings systems including an antimicrobial sacrificial floor coating composition capable of reducing and/or preventing gram positive and gram negative bacterial growth on floors. Also disclosed is an antimicrobial sacrificial floor coating remover being readily capable of removing the antimicrobial sacrificial floor coating as desired from previously treated flooring surfaces. In certain aspects, the antimicrobial sacrificial floor coatings can include a nonionic acrylic polymer; a nonionic wax; and a cationic alkyl biguanide or salt thereof. The antimicrobial sacrificial floor coating may further include a cationic wax that further stabilizes the system during storage, application, and/or post-application to a floor surface. The antimicrobial sacrificial floor coating composition has a pH of less than 7 while exhibiting continuous antimicrobial properties from full cure on a floor surface up to 1 year post-application to the floor surface at a minimum contact time of 1 hour.

A composition for paint or spot removal having a carrier, a chemical component selected from the group consisting of Tetraoxaundecane (TOU), N-Methyl-2-pyrrolidone (NMP), Diethylene Glycol Monobutyl Ether, Ethylene Glycol Phenyl Ether, Propylene Glycol Phenyl Ether, Dipropylene Glycol N-Butyl Ether, and a combination thereof, and a co-solvent. A method of using the composition to remove a stain or spot from a carpet or other non-porous or hard surface is provided.
