Gilsonite is a naturally occurring glossy black asphaltic, solid hydrocarbon resin with a low specific gravity. It occurs in its very pure natural state in a mineral called Uintaite.
Gilsonite, a unique natural hydrocarbon high in asphaltenes and nitrogen compounds, is a granular solid that is fully compatible with bitumen. It can be melted into hot bitumen, added during the hot-mix manufacturing process, or blended into a preservation treatment.
Gilsonite is also used in protective coverings, anticorrosive paints, roofing compounds, dark rotogravure printing inks, carbon electrodes for the nuclear industry, varnishes, and as a reducing agent in slurry explosives
