Description

Pitch, Gilsonite is a naturally occurring, solid hydrocarbon resin, also known as uintaite. This unique mineral bitumen is valued for its high purity, consistent quality, and ability to enhance the performance of various industrial formulations. It is an essential raw material for manufacturers in sectors requiring durable, weather-resistant, and chemically stable additives. Key industries that utilize this product include asphalt modification, foundry core washes, drilling muds, and ink production.

Application

• Asphalt & Road Construction: Used as a performance-enhancing additive to improve pavement durability, resistance to rutting, and bonding properties.
• Foundry & Metal Casting: Serves as a carbon raiser and a key component in core and mold washes to improve surface finish and reduce casting defects.
• Oil & Gas Drilling Fluids: Acts as a fluid loss control additive and stabilizer in water-based and oil-based drilling mud systems.
• Inks & Coatings: Imparts gloss, hardness, and quick-drying properties to industrial paints, stains, and printing inks.
• Chemical & Adhesive Manufacturing: Functions as a tackifier and reinforcing agent in sealants, adhesives, and rubber compounds.
• Carbon & Graphite Products: Used as a binder in the production of carbon electrodes, refractory materials, and batteries.
