  • Additives for electroplating compositions and methods for their use
    Patent number: 4981564
    Abstract: Heteroaromatic compounds having at least two nitrogen atoms may be used to regulate consistency of alloy content and of deposit thickness. Modified nonionic surfactants which lack terminal hydroxy groups are used as grain refiners having low tendency to cause foam build-up in electroplating baths. Dioxolanes may be used to produce deposits having, as desired, a white uniform matte, a semi-bright plate, or a mirror bright surface. Antioxidants are used to prevent oxidation of divalent tin.
