Abstract

L'invention concerne une composition pour l'étamage non électrique des métaux, et qui contient une source d'ion stanneux, un composant du type thiourée et un acide. Selon l'invention, elle contient au moins un composé organique appartenant au groupe comprenant : les alcools bivalents ayant un nombre d'atomes de carbone non inférieur à 2 non supérieur à 4; les composés pouvant être obtenus à partir de ces alcools bivalents au moyen de déshydratation; les composés pouvant être obtenus à partir de ces alcools bivalents au moyen de sulfuration; des oxyacides organiques n'ayant pas moins de 2 et pas plus de 3 atomes de carbone; des composés pouvant être obtenus à partir de ces oxyacides au moyen d'une estérification et ceux pouvant être obtenus au moyen d'une salification. L'invention s'applique notamment au traitement de métaux tels que le cuivre, des alliages de cuivre avec du laiton, du bronze, des alliages d'étain et de plomb, du plomb, de l'or et autres.
