Abstract: A combination of (A) a nitrogen containing water soluble polymer, (B) a water insoluble film forming polymer, and (C) gas filled, polymer walled microballoons provides a superior thermally releasable coating that (i) can be conveniently and reliably coated from a water based solution and dispersion onto surfaces to be protected against painting, (ii) is reliably stable at ambient temperatures, (iii) even after being coated with many times its own thickness of accumulated paint particles, rapidly disintegrates, along with the accumulated paint coating formed on it, upon contact with hot water, into particles of a size that readily escapes from standard paint booth grate structures, (iv) detackifies any paint particles that escape during distintegration of the combined thermally releasable coating and paint residues accumulated thereon, and (v) disintegrates into particles that float on water, so that they can be readily removed from the grates by immersing the latter in hot water, allowing a few minutes for the disintegration to take effect, and then skimming off the floating solids on the surface of the water.

Abstract: Amino resins that contain more free formaldehyde than is desirable for health and/or pollution reasons can be treated with a mixture of diketo reagents (or their nitrogen analogs) and other compounds containing amino moieties to reduce the free formaldehyde content while not diminishing, and in some cases even enhancing, the ability of the resins to function according to their normal uses. The invention is especially useful for melamine-formaldehyde resin dispersions useful to detackify paint.

Abstract: Melamine-formaldehyde resin dispersions containing more free formaldehyde than is desirable for health and/or pollution reasons can be treated with diketo reagents or their nitrogen analogs to reduce the free formaldehyde content while not diminishing, and in some cases even enhancing, the ability of the dispersions to detackify paint. Preferably, the resin dispersions are also treated with urea, which allows considerably less acetoacetamide to be used to achieve the same amount of formaldehyde reduction.

Abstract: A thixotropic aqueous liquid composition suitable for deoxidizing and etching aluminum substrates, even if they are vertical to local gravity and not immersed in any container, contains fluoride ions, an acid with an ionization constant greater than that of HF, a viscosity increasing agent that preferably is a modified xanthan gum, and both anionic and nonionic surfactants. Preferably the composition also contains a colorant, so that the thickness of the coating applied to a substrate may be visually estimated.
