The electrostatic painting process is based on the principle that opposite electrical charges attract. The result is a more uniform coat of paint, less waste, and reduced material costs.
While the electrostatic painting process was invented for and first used on Ransburg products, it had applications for many industries--including the automotive industry, where it is still the standard process for coating today. After Harold's initial development, Al Starkey, and later Edwin Ransburg, worked to develop more sophisticated processes backed by strong patent protection. In 1948, the Ransburg Electro-Coating Corporation was created to commercially sell the electrostatic technology.
