Description

Features The Zinc process is applied in a (bass) drumand (static) frame system with average thicknesses of 8 / 12 microns in white, black and iridescent finishes, all of them exempt of Cr VI. Its use is required for functional benefits and requirements of medium-high corrosion resistance, maintaining an excellent Price / Quality ratio and an optimal aesthetic appearance. The system consists of a galvanic metal deposition in an alkaline or acid Zinc electrolyte; subsequently, white, bluish, iridescent, blue, or black passivation protects the Zinc coating from white corrosion. An additional seal (Top Coat) that penetrates in the passivation ends up closing its micro cracks and pores and ensuring compliance with corrosion requirements. The Top Coats applied are perfectly adapted to the prior passivations and, besides raising White Corrosion protection, they improve the aesthetic appearance and increase the surface hardness of the coating. The coefficient of friction and torque for the fixing elements may be modified in accordance with the International Standards of the automobile industry and this is usually achieved with additives that are workpiece of the formulation of the Top Coats. The ductility of Zn is pretty good accepting subsequent mechanical deformations to the coating in thicknesses that are not very high (Max 8 microns). The application on heat-treated workpieces is excellent. The application in an acid electrolyte has the highest benefits.
