Case Study: New DuPont Technology Makes Solids Spray Like a Liquid
Reducing solvent emissions of automotive paint takes a major leap forward with the introduction of DuPont “Super Solids” ultra-low emissions coatings technology.
Application Description
Final protective clear coat applied to the Dodge Durango at the DaimlerChrysler Newark assembly plant.
Materials Selected and Why
The new Super Solids technology reduces volatile organic compound (VOC) emissions of the final protective clear coat by 25%. DuPont has been able to increase the solids content of the coating to 65% from an industry-high solids coatings standard of 50% solids and 50% solvent.
Over years of investigation, DuPont has learned to reduce the molecular weight and particle size of the solids content in paint so it behaves more like a liquid during application. This research breakthrough allows DuPont to formulate products that significantly reduce air emissions from solvents that are conventionally used to thin and disperse paint. This technology breakthrough will allow DuPont to further increase the solids content of coatings to more than 80%.
Benefits Gained
- Emissions Reduction – The new Super Solids technology reduces volatile organic compound (VOC) emissions of the protective clear coat by 25%
- Use on Existing Paint Lines – Because “Super Solids” technology can be sprayed on existing paint lines, auto assembly plants can save as much as $20 million that would be otherwise required to replace a liquid paint spray line with one designed to apply powder coatings
- Scratch & Mar Resistance – The DuPont patented technology offers a significant improvement in scratch and mar resistance to prolong the appearance of the paint finish over repeated washings without sacrificing other important appearance attributes
