As part of the Aug. 9 edition of SCIENCE, Dr. Matheson, a DuPont senior scientist, details the future of technological advances in coatings one of the world's most ancient technologies. Relatively soft coatings comprising organic materials such as blood, eggs and extracts from plants were in use more than 20,000 years ago. Coatings activity has been continuously practiced since then with gradually improving materials and application techniques. While technologies have advanced over time, the fundamental purposes of protecting or decorating surfaces have remained constant across all the centuries and cultures of civilization.
Matheson's paper in SCIENCE examines change in soft coatings technology from its current state by identifying key issues that attract research and development efforts at the dawn of the 21st century. Matheson points out that today's challenges are to decrease the environmental footprint and improve biological, mechanical and transport longevity, while minimizing the application requirements for soft coatings. Matheson notes that "a need exists in the automotive world for a painting system with lower environmental emissions (particularly volatile organic compounds, VOCs), improved resistance to environmental damage, outdoor durability, corrosion resistance, and improved application robustness. This need has been recently met with what might be considered an exemplary modern coatings system."
For example, the goal of reducing solvent emissions of automotive paint took a major leap forward this year with the introduction of DuPont "Super Solids" ultra-low emissions coatings technology at the DaimlerChry
