Imidazole and Epichlorodydrin copolymer CAS 68797-57-9

 IZE acts as a basic brightener in alkaline zinc and zinc-alloy plating, especially in cyanide-free baths.
IZE is usually used in combination with top brighteners. It is normally employed at a concentration of 10-100mg/L.The compatibility of IZE with conventional top brighteners is good. IZE has been shown to perform particularly well in combination with BPC 48.
IZE gives high throwing power and ensures that the plated metal is evenly distributed. It gives high brightness, particularly at LCD, and it inhibits blistering. Zinc-plated components plated with the aid of IZE are easy to Chromate
