CORROSION PROTECTIVE AND ELECTRICAL CONDUCTIVITY COMPOSITION FREE OF INORGANIC SOLID PARTICLES AND PROCESS FOR THE SURFACE TREATMENT OF METALLIC SHEET

摘要

Corrosion and electrical conductive protective composition and process for the surface treatment of metallic sheet with a water based composition containing an organic polymer, and inorganic compounds, the composition does too contain minor amounts of Hydrogen Peroxide or other peroxides, the essential feature of this process is that the coated surface has good corrosion resistance and good electrical conductivity of the coated surface, even that the liquid composition used does not contain conducting inorganic solid particles.
