A method for reducing adhesion between a maskant and a substrate, wherein the maskant is adhered to a surface of the substrate, the method comprising applying a composition to the maskant.

A solvent composition has an oxygenated solvent and a siloxane solvent. In one embodiment, the oxygenated solvent is propylene glycol methyl ether and the siloxane solvent is hexamethyldisiloxane or octamethyltrisiloxane. In another embodiment, the solvent composition is an azeotrope of propylene glycol n-butyl ether and decamethyltetrasiloxane. The siloxane solvent can be used in any situation where one desires to remove a silicone deposit, e.g., conformal coatings, adhesives, sealants, greases, heat transfer fluids, paints, oils, etc.

Provided are compositions containing alkyl esters derived from triglyceride oils produced from genetically engineered microalgae. Specific embodiments relate to esters derived from oils with high C10-C12 fatty acid profile. Compositions comprising the esters include cleaning products, completion fluids, work-over fluids, drilling fluids, metal working fluids, lubricants, paints, and inks.

The invention relates to a gel for removing a graffiti from a surface of a solid substrate, consisting of a colloidal solution comprising an inorganic viscosifying agent, at least one solvent, optionally at least one surfactant, and optionally at least one dye and/or pigment. The invention also relates to a method for removing a graffiti from a surface of a solid substrate, wherein the gel is applied to said surface.

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.
