Waterborne polyurethane dispersions (PUDs) are a maturing technology, with several suppliers offering a diversity of commercial products for a wide spectrum of applications
The critical challenge faced by waterborne coating formulators in this application is finding a balance between these properties and maintaining adhesion to various types of plastic.
The NCCA, along with the help of PPG Industries, Inc., and the North American Zinc-Aluminum Coaters Association (NamZAC), worked together to compare the corrosion resistance of pre-painted metal louvers on air conditioning units to those coated with three types of post-paint.
