  • Patent number: 6544939
    Abstract: A silicone dissolving composition includes an organo-acid compound such as sulfonic acid or phosphinic acid, a solvent miscible with the organo-acid and able to swell a silicone, a thickener and a small amount of mineral acid. Silicone films dissolve to a liquefied mass capable of being wiped from a substrate in a matter of minutes. The removal of automotive, electrical, and construction sealants and gaskets is simplified with the use of such a silicone dissolving composition.

  • Patent number: 5842815
    Abstract: A chemical solution for neutralizing treading surfaces includes a neutralizing agent such as an alkaline silicate neutralizing solution, a suitable dyestuff (non-indicator dye) and a masking agent (indicator dye) for masking the true color of the dyestuff. The masking agent becomes colorless at a pH of 7.0 or greater. The chemical solution is applied to a suitable treading surface, such as a ceramic tile floor, a suitable time after an acid treatment solution of hydrofluoric acid and nitric acid has been applied to the treading surface. Use of the indicator dye in combination with the non-indicator dye in the chemical solution yields a strongly visible color change which distinguishes the areas that have been sufficiently supplied with neutralizing solution from those that have not been sufficiently supplied with the neutralizing solution.

  • Patent number: 5670469
    Abstract: Improved compositions containing a visible coloring agent, such as a pigment or dye, together with a polymer or hydroxylated aliphate alcohol, and an active ingredient defined as a surfactant, a therapeutic agent or biocide, are disclosed. The detectable agent is readily visible under normal white light, and provides a technique for monitoring disturbed and undisturbed areas on a surface. Such is useful in the described methods for cleaning and/or decontaminating a surface, such as in the decontamination of equipment and clothing used during hazardous spill response. The compositions are adherent to a variety of different materials, including Teflon.RTM..
