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

摘要

Corrosion and electrical conductive protective composition and process fo r the surface treatment of metallic sheet with a water based composition con taining an organic polymer, and inorganic compounds, the composition does to o contain minor amounts of Hydrogen Peroxide or other peroxides, the essenti al feature of this process is that the coated surface has good corrosion res istance and good electrical conductivity of the coated surface, even that th e liquid composition used does not contain conducting inorganic solid partic les.
