Key Features With our specialization in this domain, we are able to provide a finest quality range of Gilsonite. It is soluble in aromatic and aliphatic solvents, as well as petroleum asphalt. Due to its unique compatibility, Gilsonite is highly utilized to harden softer petroleum products. It is brittle and can be easily crushed into a dark brown powder. And also Gilsonite (Uintaite) [12002-43-6] is a natural hydrocarbon substance of the class known as asphaltites(see Asphalt), occurring as a coal-like solid which is mined much like other minerals and sold essentially in its native state. We provide this range at most reasonable rates.
