Advertisement for Yarmor F, a naval stores product manufactured and sold by the Hercules Powder Company for use as a frother. This advertisement appeared in the May 1945 issue of Engineering & Mining Journal.

Formed in 1912 as part of an anti-trust settlement with DuPont, the Hercules Powder Company (later Hercules Inc.) initially specialized in the manufacture of explosives and smokeless powders and subsequently diversified its business to encompass a variety of industrial products, including pine and paper chemicals, synthetics, pigments, polymers, and cellulose.
