Autodeposition Paint
Autodeposition Paint is a chemical coating used in a process where an organic polymeric emulsion chemically deposits on the surface of a clean metal substrate. Autodeposition Paint is known as the "simple solution" because it reduces the number and complexity of stages involved in painting parts.
A unique feature of the autodeposition process is the formation of a uniform film over the entire surface of the work piece, even in difficult-to-reach areas. Scanning Electron Microscopy (SEM) photos show a uniform, tight, autodeposited wet film before coalescence/curing, and consistent coating thickness around edge of razor blade. This allows the coating dispersion to flow into and around the most complex shapes. Unlike coating processes that require a charge to deposit the coating (i.e, where electrical energy is required to "throw" the coating into recessed areas) autodeposition will coat tubular, assembled, or intricate design areas uniformly.
Simplicity in coating process design and control are critical to providing value. Autodeposition Paint can improve the total value and productivity of manufacturing operations. It meets the stringent environmental requirements for today and tomorrow.
An Autodeposition Paint bath consists of a mildly acidic, latex emulsion polymer, DI water, and other proprietary ingredients.
