  • This invention relates to a method and composition for repairing damaged painted metal surfaces.

  • a problem often met with in applying the paint is the difficulty of applying the paint to the scratched or chipped portion without also overpainting the surrounding unmarred finish with excess paint.
  • the overpainted portion no longer matches the remainder of the surface and thus continues to lack an unblemished appearance which is desirable for a complete repair of the original finish.
  • individuals may have attempted to wipe away the excess new paint with a dry cloth, the problem has always been to remove the excess paint without, on the one hand, marring the original finish in those areas immediately adjacent the scratch or chip and, on the other hand, removing all of the paint applied to the chipped or scratched portion.

This was accomplished without removing the paint from the exposed metal surface.

  • Example 1 The procedure in accordance with Example 1, above, was repeated but utilizing as the touch-up liquid composition painters ' naphtha, as purchased. It was found to be necessary to rub with greater force, and that greater care needed to be taken to avoid removing paint from the scratched area and to avoid marring the original surrounding finish.

Abstract

Procédé de réparation de surfaces métalliques endommagées. Une surface peinte abîmée, par exemple la tôle peinte formant les carrosseries de voitures ou de camions qui ont été abîmées par des égratignures ou des ébréchures faites à la peinture, exposant le métal, peut être retouchée afin de retrouver l'apparence d'une surface uniformément peinte et d'empêcher la corrosion du métal exposé, grâce à l'application d'une peinture de retouche à la surface métallique endommagée. On frotte ensuite la surface retouchée ainsi que la surface finie et non abîmée immédiatement environnante à l'aide d'un matériau en feuille souple et moelleux qui a été imbibé d'une composition de solvant pour peinture de retouche afin d'enlever tout excédent de peinture étalé par inadvertence sur l'ancienne finition entourant l'égratignure ou l'ébréchure. On ne frotte la surface retouchée avec le matériau en feuille souple imbibé de solvant que lorsque la peinture de retouche a en partie séché, généralement 1 à 15 minutes environ après l'application. La composition de solvant comprend un solvant liquide paraffinique choisi à partir du groupe composé de benzène substitué par l'alkyle inférieur et de composés d'hydrocarbure cycloaliphatique et aliphatique oxygéné et de tels composés substitués par l'halogène.
