Abstract

Patente de Invenção: <B>"MéTODO PARA REMOçãO DE UM REVESTIMENTO ALUMINìDEO DE UM SUBSTRATO"<D>. Um método para remoção de um revestimento de aluminídeo de um substrato inclui as etapas de colocar a superfície do substrato em contato com pelo menos uma composição decapante para degradar o revestimento. A composição decapante inclui um ácido sulfónico alifático ou aromático, e pelo menos um aditivo. O revestimento é então removido.
