Gilsonite in oil drilling industry
Gilsonite is used in drilling mud fluids and oil well cementing. The addition of specially-treated Gilsonite to water-based drilling fluids helps minimize hole washout by stabilizing troublesome shale’s, and seals off highly permeable sands while reducing torque and drag. The addition of Gilsonite to oil well cements reduces slurry weight without loss of compressive strength and acts as an effective bridging and plugging agent to seal fractures in weak formations while cementing.
Gilsonite in foundry
Gilsonite is combined with coal and other ingredients as an additive in foundry sands to insure the quality of the molded part. In sand case, by adding Gilsonite and asphalts at approximately one third the level of sea coal the pitch had the same 900°F (482.2°C) volatiles. At this level, loss on ignition with asphalt, and Gilsonite was less than 50% of that obtained with seacoal and pitch while the Gilsonite and asphalts evolved less total gas when compared to seacoal and pitch Gilsonite had the least visible smoke generated in the laboratory tests. The lower gas evolution should reduce ventilation load on the pouring floor. The physical property relationships developed in new sand mixes were confirmed on system sand using Gilsonite as an additive. Casting finish of a Gilsonite mix was equal to seacoal.
Gilsonite in pipe coating
Gilsonite is used for preventing the pipes from corrosion and it acts as an additive in pipe isolator, which increases the pipe life significantly. Gilsonite is used in different industries as a resin for waterproofing purposes, for example in Automobile industry it is used as an additive in coating car’s under body.
Gilsonite in paint and ink
Gilsonite is used in ink manufacture principally as a carbon black dispersing agent or wetting agent. It performs this function at concentrations of 2% to 5% of the finished ink recipe. Gilsonite itself is a hard, high softening point resin, and it could be used in the finished ink formula for its resinous abilities to offset the hydrocarbon and other resins. However, this requires a concentration on 10% to 15% Gilsonite in the finished ink recipe before it performs this function. This is possible, but difficult, because of dealing with Gilsonite's ash and aromatic contents at such high concentrations. At such high concentrations, there is too much as to filter, the viscosities start too high and increase even higher, etc. Therefore, most ink makers use Gilsonite at low concentrations for carbon black dispersing only and use other resins such as "C5/C9" hydrocarbons or modified rosin phenolics for the ink's resinous ingredients.
Gilsonite in rubber
In the Rubber industry adding Gilsonite (Natural Asphalt) with Carbon black will result in having a much more reinforced rubber. This will take effect as Gilsonite facilitates the absorption of carbon black in natural rubber during the mixture with other components, as Gilsonite has high amount of Carbon content it performs well in situations that Carbon black is used in hot mixes also due to special Gilsonite characteristics it will result in a rubber with higher abrasion wear strengths which is perfect for using in tire industry. Natural Asphalt acts as a perfect binder and provides better results with cheaper costs while using in synthetic rubber manufacturing or natural rubber mixtures.
Gilsonite in asphalt and road paving
Gilsonite is used as a performance-enhancing agent for asphalt mixes. Gilsonite can partially or totally replace, or complement, the use of SBS polymers in modified asphalts at a fraction of the cost. Gilsonite-modified asphalts have higher stability, reduced deformation, reduced temperature susceptibility and increased resistance to water stripping than non-modified asphalts. Gilsonite is also used to make both solvent-based and emulsion pavement sealers with superior appearance and weathering properties.
