Waterborne Automotive OEM Primer Surfacer Makes a Splash in North America

Waterborne automotive OEM primer surfacers have been commercialized and available to European Assembly Plants since early 1990. Besides the advantage of low VOC, physical properties such as chip and impact resistance are excellent. Technical problems encountered are mostly application related such as sensitivity to high relative humidity. Pop and sag resistance at high film builds have been minimized by application technique and formula modifications.

With solventborne high solids primer surfacers being pushed to their VOC limits by more stringent regulations in North America, waterborne primer surfacers are “primed” to meet the challenge.
