Thirty years ago, the Australians went with the best acrylic latexes of the day and their own version of the German factory-ground pigments to develop water-based coatings that had the capability to provide the heat reflecting they needed. In Australia, there was a huge need for durable, efficient, cool coatings for metal and tile roofs that could be inexpensively field-applied to buildings in the torrid Outback, tropical Queensland and the rest of the vast Australian continent. Variations of the technology were taken up in military applications as well. The high cost of the metal roof coating system known as Kynar™ (over $100 per gallon) only suited large-capital corporate and industrial jobs and those with unlimited budgets since the lifespan of 20 to 30 years before these coatings failed. This trend was brought to the high-end, residential marketplace into the 1980’s and hasn’t changed since. Metallic pigments are much more efficient in reflecting away the sun’s radiation (infra-red spectrum) than standard organic liquid tints. Their chemistry was toxic solvent based, and they were exceptionally durable, eventually becoming the standard for commercial and industrial buildings. These coatings contained infrared (IR) and mixed metal oxide (MMO) pigments, were factory applied, and were expensive. The first use of designed-in, energy efficient German pigments in American paints occurred in the 1970’s in collaborations between metal roofing manufacturers and makers of industrial coatings. Offered at competitive cost per unit with the same application requirements as standard paints and coatings, this article will show how this growing category of energy efficient, “green” paints and roof coatings provide a high return on investment that will become the norm in the not too distant future.įactory Coated Metal Roofs – German Engineering These paints and coatings utilize fade-resistant, inorganic pigments and are useful for all types of architectural surfaces. To start understanding the fundamental importance and value of solar-reflective exterior paints and coatings, we need to learn their history. History of Solar-Reflective Paint and Roof Coatings By providing a high return on investment, these paints and roof coatings can greatly benefit large companies to individual homeowners, and everywhere in between The growing category of “green”, energy-efficient paints offers both financial and environmental benefits to consumers.
