In building and construction we wish to point out the traditional benefits of epoxy resins used in coatings and construction materials. While innovation continues to make these materials cleaner and greener, their key impact on society is to ensure long asset life at lowest maintenance cost.
Considering the amount of infrastructure that is constructed from steel in an industrialized nation, the cost of replacing lost assets due to corrosion (Road, rail, buildings, automobiles, power, water, oils and gas, chemical industry etc) would equate to between 3 – 4% of the GDP of that country. The latest estimate from the USA by NACE was that this figure for the USA alone would be about 2.5 Trillion dollars.
There is also the carbon emission argument for producing coatings with a long service life (for which epoxy resins are a key ingredient) in terms of the production of the raw materials and finished products, application, transport of goods. The fewer the number of applications and maintenance cycles, the better. Next to lightweighting we see epoxy play a key role in electrical powertrains for cars. This is really an extension of the use of epoxy as encapsulation material in under-the-hood electrical components in traditional cars. Mass production, high performance and reliability and a long lifetime in harsh environments are key. And epoxy resins can provide heat resistance and fire protection in battery compartments.
