Abstract

"AGENTE DE DECAPAGEM, MéTODO DE FABRICAR O MESMO E USO DE URéIA NO MESMO". Um agente de decapagem estável a longo prazo para a remoção de uma camada de óxido em um aço inoxidável após tratamento térmico, como soldagem, cujo agente de decapagem compreende ácido nítrico e cargas e constitui-se de uma pasta de decapagem ou gel de decapagem a ser revestido no aço inoxidável tratado termicamente ou de um líquido de decapagem a ser borrifado no aço. De acordo com a invenção, o agente de decapagem também compreende uréia para formação reduzida de emanações nitrosas quando o agente de decapagem é utilizado.
