Grit blasting of metal surfaces, a routine surface preparation technique prior to painting, is expensive, labor-intensive, time-consuming, and generates a large amount of hazardous, powdery waste. A less-hazardous and lower-cost alternative surface preparation technique that can ensure long service life by providing good adhesion to the substrate is highly desirable. To that end, NEI Corporation has developed a proprietary nanocomposite pretreatment coating called Nanomyte® PT-20, which is designed to:
• Improve the adhesion and corrosion resistance of paint systems on steel, aluminum and other metal substrates;
