As lead exits the world’s last car engines, it is also finally disappearing from car coatings.
DuPont, the world’s top car paint maker and the first to mass-market colored car coatings, has announced that its global DuPont Refinish business will stop using leaded pigments in its products by the end of 2012.

All passenger-car formulas in the aftermarket paint brand have already been converted to lead-free pigments, the Belgium-based company says.
For commercial vehicles, all remaining lead-containing topcoats in the company’s Centari MasterTint and Imron PowerTint brands are now being converted to lead-free formulas, so that body shops will have immediate access to alternatives by the year’s end.
Customer demand for the heavy lead pigments has kept them going, but DuPont Refinish is also concerned with safety and environmental issues surrounding the products’ manufacture and use, said Linda Van Calster, marketing communications manager EMEA.
“Whilst the use of leaded pigments was discontinued in the OEM arena a number of years ago, customer demand and the perceived benefits of lead pigments in the industrial and refinish segments has meant supply has continued,” she said.
“With our strong links to our parent company, DuPont, it is important to reinforce its core direction of sustainable growth coupled with a promise to safety, health and environmental excellence.”
The company is promoting its new lead-free alternatives through its color retrieval website weekly updates.
Meanwhile, to help customers avoid major increases in topcoat paint consumption, the company is recommending the use of its ValueShade primer, available in seven shades of gray, to improve hiding and topcoat coverage.
Van Calster says the online ValueShade color formula retrieval technology makes the product easy to select and use.
DuPont, GM and Cars
DuPont was the first company to develop a car paint that was available in a palette of colors—a welcome novelty for customers tired of Henry Ford’s famous black.
Not only that, but the DuPont product could be sprayed on, rather than hand brushed, reducing the painting time of a vehicle from weeks to just six hours.

The company’s first car paint, named Duco, was a nitrocellulose lacquer rolled out in 1922. Within four years, Duco was in use on General Motors’ first paint line and became the standard finish on all GM cars, according to DuPont’s published history.
DuPont and GM had formed a relationship in 1914, when Pierre S. du Pont (great-grandson of founder E.I. du Pont) bought stock in the car maker. Du Pont soon became a board member of GM, then board chairman.
After World War I, DuPont treasurer John J. Raskob persuaded his board to invest $25 million in GM. When the carmaker was on the brink of bankruptcy in 1920, Pierre du Pont became president of GM, and the GM holdings made up half of DuPont’s total earnings.
DuPont disposed of all its GM stock in 1961.
