Can anyone explain to me why the article states "The chemicals had been used since the 1940s in consumer products and industry, including in nonstick pans, food packaging and firefighting foam. Their use is now mostly phased out in the U.S., but some still remain." but I see more categories of products using DWR coatings as a selling point every year?
