    Abstract: An otherwise conventional solid Jernstedt salt composition for activating metal surfaces to improve the quality of subsequently deposited phosphate conversion coatings on the activated metal surface and which rapidly dissolves, utilizing in the composition a mixture of sodium and potassium salts, preferably condensed phosphate salts, in such amounts that the ratio of potassium to titanium is within the range from 8.0:1.0 to 40:1.0 and the ratio of potassium to sodium is within the range from 0.9:1.0 to about 2.5:1.0.

    Abstract: Many prior art processes for cleaning predominantly organic hard surfaces have been found to be considerably less effective in removing very fine particles on such surfaces than are the best cleaners for metallic surfaces. However, it has been found, and forms the basis of this invention, that fine particles can be removed effectively from organic surfaces by an indirect process of first forming a thin solid coating over the surface and then removing the solid coating, into which the fine particles that formerly contaminated the surface to be cleaned have presumably become incorporated. Substantially hydrolyzed poly(vinyl acetate) has been found particularly useful for forming the thin solid coating when this coating is to be removed by treatment with an acidic aqueous solution; acrylate polymers are preferred if the solid coating is to be removed by an alkaline aqueous solution. In either instance, in order to obtain good wetting without damaging the surface to be cleaned, the material that forms the bulk of the solid coating is preferably applied to the surface to be cleaned in an aqueous solution or dispersion that also contains surfactant molecules that include imidazoline moieties. A method of quantifying the degree of removal of solid particles is also provided.

    Abstract: A "highlighter" liquid for detecting cosmetic defects in non-metallic surfaces, particularly those intended for high quality automotive finishes comprises organic substances each molecule of which contains at least one continuously chemically bonded chain or ring of atoms in which there are at least two carbon atoms and at least two oxygen, nitrogen, sulfur, and phosphorus heteroatoms, the carbon atoms and heteroatoms being arranged in such an order along the chain or ring that (i) each heteroatom is bonded to at least one carbon atom and (ii) the chain does not include more than three consecutive continuously chemically bonded carbon atoms Particularly suitable materials include glycerin, propylene glycol, low molecular weight glycol condensation polymers, and monoethers of these glycol condensation polymers. Water is also usually present in the highlighter liquid, which has a long open time and does not damage the substrate even if left in place for a day or more.
