Coatings Technology: Learning to Accommodate the Local Weather

We’ll confine our discussion here to obvious weather differences, but we won’t get into how coil coatings formulators accommodate those differences. That’s a discussion for another day. Just know that steel and aluminum companies, pretreatment suppliers, and coatings chemists are working hard to formulate a coil coating system that provides the necessary performance for a particular region.

Weathering Devices: Let the Sun Shine Down

imagesAbout 75% of the North American coil coating industry is dedicated to building products. Since the lifetime of these products is measured in decades, as opposed to merely years, the weathering performance of the coatings used for this market is critical. Understanding how coatings perform, therefore, is essential. There are many approaches to studying weathering performance, and one of the more interesting techniques to accelerate the weathering process involves the devices described in these two ASTM standards:
