General definition
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. Gilsonite is readily soluble without heating in solvent especially in Xylene, Toluene, and Benzene and in the most chlorinated solvent.
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 ink powder is compatible with drying oils, vegetable oils, resins, hydrocarbon resins, elastomers, asphalts, and waxes for specialty applications.
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.
Gilsonite Usage in Ink
Gilsonite has been used as the first wet carbon agent in black and brown inks for newspapers and magazines. High concentrations of Gilsonite have been used in newspaper printing inks. Gilsonite competes with oil-based hydrocarbon resins, phenolic resins and metal resins. The main usage of this material is for dispersing black carbon particles which comprise the black color of the printing inks. This material is used in black ink as a cost-effective replacement for other resins.
When you read a newspaper or magazine, you touch the benefits of Gilsonite. The jet black in many heatset printed magazines and high-quality publications simply would not be possible without the excellent carbon black dispersion properties of Gilsonite. Gilsonite delivers economic performance too. It is more cost effective than hydrocarbon and phenolic resins. Gilsonite and Gilsonite resin, derived by solvent extraction of raw Gilsonite, are 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.
How to make stabilized ink with Gilsonite powder
- Carbon black in the range 10% to 27.8%
- Asphalt powder in the range 17.6% to 23.5%.
- Asphalt powder in the range 17.6% to 23.5%.
Advantages of gilsonite in ink
Superior binding and carbon black dispersion make gilsonite the ideal inks additive.
The unique natural properties of Gilsonite make it the must-have, high-performance ink additive for top quality newspapers, magazines, and other publications.
Gilsonite in Inks industry is used basically as Carbon Black Dispersion Ink Additive considering the specifications of Gilsonite to be highly solvable in natural and synthetic oils. In Black Inks, Gilsonite Selects a better approach naturally to bond well with the paper and provides a more sustainable print.
Gilsonite Powder Solubility
Gilsonite 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 Naphtha, Oils and Mineral Spirits), but mixing time is longer. Without heating, the pulverized grade is recommended. Gilsonite is not soluble in water, alcohols, or acetone.
Films developed from Gilsonite ink powder have a dark colour with little bronzing effect. Solutions do not thicken upon ageing. powder is compatible with drying oils, vegetable oils, rosins, hydrocarbon resins, elastomers, asphalts, and waxes for speciality applications. It has limited solubility in most alcohols and ketones.
Gilsonite Ink Additive
A non-petroleum base newspaper printing ink comprising a blend of Gilsonite flakes and tall oil fatty acids, together with carbon black pigment. the proportion of the ink Gilsonite and tall oil fatty acids may be varied as viscosity requirements change due to differences in press speeds, newsprint characteristics and the like. The ink Gilsonite thus has readily adjustable viscosity together with an enhanced flow and penetration characteristics, while being extremely economical to manufacture.
