Optimization of the process of organic film formation by cataforetic deposition, aiming for energy savings, environmental protection and adaptation of the process to national climatic conditions

Abstract

Still a recent technology, painting by cathode process can still be improved. The development of this area is heading towards producing films aiming for products with reduced or non-existent lead levels, with lower cure temperatures and lower levels of pigmentation in the film applied. The process of painting by cathodic electro-deposition is mostly used in trucks and vans, as with automobile chassises, since it can be applied on a variety of substrates such as: cold-laminated steel, aluminum, galvanized iron and iron pre-coated with zinc alloys. The advantages of this process are greater anticorrosive power and less environmental pollution, among others. The objective of this project is to implement the cataforetic painting process in an interested company, seeking to evaluate the existing commercial systems. It is intended to analyze the principal parameters of the process (deposition time, voltage and mode of voltage application and temperature), to obtain better performance in relation to energy savings, environmental protection and resistance to corrosion. In the second phase, the focus will be on the influence of the surface preparation to find alternatives principally for the zinc and the zinc alloys, with a view to replacing the chromatization processes with adherence layers for the electrodeposited paints.
