High Film Build Cathodic Electrodeposition Provides Improved Corrosion Protection 831813

Cathodic electrodeposition has become the dominant method of priming cars and trucks throughout the world. This achievement is a result of the superior corrosion resistance of cathodic paint technology and inherent advantages of the electrodeposition process.High film build cathodic electrodeposition of 30 to 35 microns provides a significant improvement in corrosion resistance. This new technology produces increased film build, greater chip resistance, and better corrosion resistance as indicated by salt fog, scab, test track, and other corrosion tests. This paint uses the electrodeposition process to apply the majority or all of the primer requirements; it provides economic efficient paint utilization, process simplification, and high quality to meet the goals of the automotive industry. As a single primer coating or as a base for a primer surfacer, it provides good film smoothness and metal filling properties.More than 20 electrodeposition tanks are filled with this quality product to coat car or truck bodies and other parts. The application characteristics are related to conventional cathodic electrodeposition, but the deposited film is notably altered to achieve these improvements.
