GNS Science and Resene Paints to Develop Roof Coatings Using Nanotechnology
LOWER HUTT, New Zealand - A joint project between New Zealand-based companies GNS Science and Resene Paints will develop a new low-cost way of producing a powder containing metal oxide nanoparticles that can be readily incorporated into existing paint manufacturing methods. Once the technology is perfected for roof coatings, it is likely to be available for other applications such as marine and automotive coating products, said project leader John Kennedy of GNS Science.
“The global market for colored coatings with infrared reflective pigments is valued at $250 million a year, and it is growing at about 12 percent annually,” said Kennedy. “Improvements in reflectance will translate into much greater value for consumers due to reduced energy bills, lower maintenance and replacements costs, plus a larger color range.”
