Gilsonite and Gilsonite resin, derived by solvent extraction of raw Gilsonite, arc 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, Gilsonite or Gilsonite resin binds the pigment to the paper. yielding the high-gloss print that resists rubbing off. Gilsonite 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 Gilsonite resin is used in offset printing inks in concentrations of 15% or more to replace more expensive resins.

Gilsonite is readily soluble without heating in solvent especially in Xylene, Toluene, and Benzene and in the most chlorinated solvent. A non-petroleum base newspaper printing ink comprising a blend of Gilsonite flakes and tall oil fatty acids, together with carbon black pigment.

Gilsonite powder blending in newspaper offset printing inks as non-petroleum additive comprising a blend of Gilsonite flakes and tall oil fatty acid together with carbon black pigment. The proportions of the gilsonite powder and the tall oil fatty acid may be varied, as viscosity requirements change due to differences in press speeds, newsprint characteristics, and the like. The ink thus has readily adjustable viscosity, together with an enhanced flow and penetration characteristics, while being extremely economical to manufacture.

Gilsonite inks powder is readily soluble without heating in aromatic solvents (Benzene, Toluene, Xylene) and in most chlorinated solvents. It is also soluble without heating in aliphatic and low aromatic solvents (VM&P and other Naphthas, Ink Oils and Mineral Spirits), but mixing time is longer. Without heating, the pulverized grade is recommended.
Films developed from Gilsonite ink powder have a dark color with little bronzing effect. Solutions do not thicken upon aging. Gilsonite ink powder is compatible with drying oils, vegetable oils, resins, hydrocarbon resins, elastomers, asphalts, and waxes for specialty applications. It has limited solubility in most alcohols and ketones.

Printing Inks, Gilsonite is an important cost-effective ingredient in the manufacture of high-quality vehicles for dark printing inks.

RAHA GILSONITE Inks grade is a quick drying high gloss and corrosion resistant asphalt enamel. It is using for fully resistance to water, acids, alkalies, electrolysis and natural elements.

RAHA GILSONITE Resin competes advantageously with petroleum-based hydrocarbon resins, phenolic resins, and metal resinates, all of which it can complement or replace to various degrees. Various concentrations of RAHA Gilsonite Resin are used to manufacture law-rub-off news inks with superior gloss and tack properties.
