gilsonite usage in asphalt drilling ink print paint pavement Gilsonite has an extremely wide range of uses; these uses have changed over time with new technology and industrial needs. Current uses of Gilsonite are discussed in the following subsections.

Gilsonite has an extremely wide range of uses; these uses
have changed over time with new technology and industrial needs. Current uses
of Gilsonite are discussed in the following subsections.

Gilsonite is oil welldrilling mud additive

For many years, Gilsonite has been added to drilling fluids to stabilise
boreholes through shale stratigraphic intervals, preventing borehole
enlargement. It is plugs micro fractures, bedding plane voids, and pore spaces
and forms a thin film on the borehole wall. Gilsonite is added at about 1 to 3 kg per barrel
of drilling mud. It is also reduces drill string torque and drag, and thus
reduces the likelihood of stuck drill strings Bore-Plate, a speciality product
for this application, is a mixture of grades (75% to 85% of the formula),
surfactants, and dispersants designed for use in water-based oil well drilling
fluids. Oil Well Cementing is added to oil well cement for use in primary
cementing of lost-circulation zones in surface, intermediate, and production

It also is used for secondary cementing such
as squeezing, recementing above inadequate fill-up, and plugging back to
reestablish drilling fluid circulation. It is used because of its low density,
low water absorption, chemical inertness, mechanical strength, granular nature,
and minor deformation under high pressure. These properties allow it to
effectively enter, bridge, and seal lost-circulation zones. Typically 11 to 23
kg of Gilsonite is
used per sack of cement.

Gilsonite is asphalt
pavement binder modifier

Is added to asphalt paving mixes to Improve pavement
performance. It is increases stiffness and viscosity of the binder Improves
load-bearing capacity and reduces highway rutting Improves ductility and
resistance to low-temperature cracking Increases durability of the pavement
Improves workability of the mixture during paving. Typically 5% to 15% is added
to the mixture’s binder.

Gilsonite asphalt
driveway coat sealer

Preparations of Gilsonite, solvents, and other additives are used to coat weathered asphalt driveways, playgrounds, and other asphalt surfaces to improve appearance, reduce water infiltration, and slow deterioration of the asphalt pavement. Built-up Roofing Component is added to roofing asphalts. The compound acts as a water proofing agent and as an adhesive that binds layers of roofing felt together.

Gilsonite is
stabilizer of foundry sand

Is an additive in sand mixtures used to make molds for casting
gray iron and pig iron. Adding such useful material makes a better mold that
imparts a smoother finish to the cast piece and is easier to remove from the
cast item.

Ink Component

And Gilsonite resin, derived by solvent extraction of raw
material is used as carbon black wetting agents for black news ink and heat set
and gravure ink. In addition to wetting and dispersing the carbon black
pigment, The resin binds the pigment to the paper, yielding high-gloss print
that resists rubbing off. It can be mixed with other natural and synthetic
oils, resins, and other additives to yield ink suitable for different types of
printing presses and printing applications.

Gilsonite typically comprises 2% to 5% of ink formulations. Refined resin issued in offset printing ink in concentrations of 15% or more to replace more expensive resins. Miscellaneous Applications is used as an organic fuel in fireworks; for manufacture of high purity carbon electrodes in the nuclear industry; as a binder in metallurgical additives and refractories; and in manufacture of con-tact and hot melt adhesives, friction products, and pipe coatings.

Gilsonite component

Gilsonite added to bitumen-based paints to increase hardness, adhesion, UV stability, and water and chemical resistance. Paint formulations are often used on automobile frames and radiators. It is also an ingredient in wood stains.
