Abstract

A cyanide-free, alkaline, bright zinc plating bath contains one or more polyamines, other known brightening agents and additives and, as a separate compound, thiourea, preferably in amount 0.5-15 grams/litre. The polyamines can be added in amount 0.5-15 grams/litre; brighteners such as benzaldehyde, coumarin vanillin anisic aldehyde and heliotropin 0.4-4 grams/litre; colloids such as gelatine, gum arabic and tragacanth 1-2 grams/litre; pore preventing agents such as octyl, decyl, lauryl and dodecyl sulphonate 1-5 grams/litre. Zinc can be added as zinc oxide dissolved in sodium hydroxide.
