Bringing naturally superior properties to materials across diverse industries

GILSONITE® uintaite adds performance in a wide variety of industrial applications. GILSONITE® uintaite is a naturally occurring hydrocarbon resin with properties that enhance the performance of critical applications across multiple industries.


There is only one source of GILSONITE® uintaite.

GILSONITE® uintaite is only found in AGC mines in North Eastern Utah USA. Some companies claim to offer “Gilsonite” from other parts of the world, but those products are simply misidentified. Their performance can’t compare to the physical and chemical properties of true GILSONITE® uintaite.


Natural GILSONITE® uintaite is non-hazardous and non-toxic. It is a very pure resinous rock, formed of a complex combination of different kinds of hydrocarbons. This unique natural combination, rich in nitrogen and beta-carotenes and low in sulfur, is what makes GILSONITE® uintaite so special. Its unique chemical and physical properties make GILSONITE® uintaite a high-performance, multipurpose additive that is also a cost-effective solution.


This versatile, multipurpose additive has significant health, safety and environmental (HSE) advantages over synthetic products. OSHA Material Safety Data Sheets classify GILSONITE® uintaite as non-toxic, noncarcinogenic, non-mutagenic and it requires only standard PPE safety measures. GILSONITE® uintaite is exempt from REACH regulations.
