ELECTRODEPOSITION COATINGS history- why Electro-deposition- types of Electro-deposition- comparative study of CED and AED
ELECTRODEPOSITION COATINGS Electro-priming of motor vehicle began in the late 1960s & within few years almost all mass-produced vehicles in industrialised countries were primed in this manner. The main reason for the universal and rapid acceptance of this process despite its higher initial installation, running & material costs were: Uniform film thickness in the range of 15-35 µ Greater operating flexibility Superior mechanical & corrosion performance properties Greatly reduced solvent emission & hazard Highly efficient with upto 95%of the coating material being utilised. Until mid 1970s all the electro primers used by the automotive industry were of the anodic type & resin systems included maleinised oils, polyesters, epoxy ester, or poly-butadiene polymers combined with specific anticorrosive pigments.
