Gilsonite Ink Grade:
PUB-LTD Gilsonite Ink Grade 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 (VMP and other Naphtha, Ink Oils and Mineral Spirits), but mixing time is longer. Without heating, the pulverized grade is recommended.
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 Gilsonite resin binds pigment to paper, to wetting and dispersing carbon black pigment. Yielding high-gloss print that resists rubbing off. Gilsonite can mixed with natural and synthetic oils, resins, and other additives. Uses to yield ink suitable for different types of printing presses and uses. Gilsonite typically comprises 2% to 5% of ink formulations.
Also refined Gilsonite resin, replaces for expensive resins in offset printing inks by doping of 15% or more. Gilsonite powder blending in offset printing inks. It uses as non-petroleum additive comprising a blend of Gilsonite flakes and tall oil fatty acid together with carbon black pigment. Proportions of gilsonite powder and tall oil fatty acid may be varied, as viscosity requirements change due to differences in press speeds, newsprint specs. The ink thus has readily adjustable viscosity, together with an enhanced flow and penetration characteristics. Also is extremely economical to manufacture.
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, rosins, hydrocarbon resins, elastomers, Asphalts, and waxes for speciality applications. It has limited solubility in most alcohols and ketones.
