  • Publication number: 20240426753
    Abstract: Provided are methods and compositions for assessing a surface to be ready for subsequent treatment. A photoluminescent dye is used in the rinsing stage by mixing it with water and a non-fugitive chemical/inhibitor, leaving a film on the surface. Alternatively, the surface is treated with an acidifier solution containing a photoluminescent dye to ensure complete coverage. The surface is rinsed with an alkaline solution including a fugitive chemical to indicate complete removal of the gel. The dye emits photoluminescence under UV light, indicating film thickness. In the evaluation stage, an inspector checks photoluminescence. Photoluminescence intensity to determine readiness for treatment. If the surface fails, the surface is rinsed further with water to remedy the failure. Otherwise, the surface is subject to subsequent treatment. Semi-durable coatings requiring additional application can be identified by weak or lack of photoluminescent intensity.

  • Publication number: 20230159856
    Abstract: Embodiments of the present methods and solutions that operate to prepare a metal surface to be ready for coating or primer. The surface is operated on using mechanical or pressure impingement operation in conjunction with application of medium comprising dimethylethanolamine (DMEA) and water (DMEA diluted in water). Embodiments of the present invention can perform the wash or decontamination to leave a clean surface that provides excellent performance in durability and rust resistance after being coated or primed. Other cleaning chemicals if added may reduce the performance and interfere with the desired objective. Other surfaces are contemplated.
