Disclosed are three organic solvent cleaning formulations. In one embodiment, the formulation is methyl or ethyl lactate and propylene glycol methyl ether. In another embodiment, the formulation is methyl or ethyl lactate and propylene glycol propyl ether. In a third embodiment, the formulation is ethyl lactate and isoparaffins of isoundecane and isododecane with propylene glycol propyl ether added as a stabilizing agent.

Nonflammable mild odor solvent cleaner

Disclosed are formulations for producing chemical solvent admixtures that can be employed to clean a surface for further work; and that can be applied to cloths for the cleaning operation yet alleviate problems with solvent evaporation into the atmosphere to cause many legal and environmental problems, and a method of storing and disposing of cloths soaked with the formulation that alleviates current problems.

Cleaning formulation and method that alleviates current problems

A method for forming and preserving a permanent record of inspections of workpieces or the like having drilled holes or other metallic surface conformations characterized by applying a castable, plural component, magnetically active material comprised of room temperature vulcanizing, or polymerizing, rubber containing magnetizable particles and specific sensitizing agents; magnetizing the area to be inspected, so as to cause migration of the particles in the rubber before the viscosity becomes too high for the magnetized particles to migrate to the situs of an imperfection, or flaw; forming a magnetic rubber inspection replica or record of the alignment of the magnetizable particles adjacent the interface between the casting and the workpiece by increasing the viscosity of the rubber above 4000 centipoises and to flexible elastic form so as to immobilize the particles; removing the magnetic rubber inspection record thus formed and inspecting for concentrations of the magnetizable particles to delineate flaws; and carrying out post-inspection procedures. Also disclosed are specific formulations and ingredients thereof, including delineation of components that cure the problems of the prior art.
