What Makes Gilsonite a Key Ingredient in Ink
In the ink industry, Gilsonite acts as a binder, carbon black enhancer, and viscosity modifier. It brings brilliance to colors and creates fast-drying, smudge-resistant finishes, especially useful in newspaper, gravure, and packaging inks.
Technical Specifications
Viscosity Enhancer and Resin Alternative
- Softening Point: 150°C – 220°C
- Melt Viscosity: Optimized for ink dispersion
- Color: Jet black to dark brown
- Purity: Low ash (under 5%) for ink-grade use
Solubility Profile in Ink Solvents
Gilsonite dissolves well in:
- Aromatic hydrocarbons (e.g. toluene, xylene)
- Aliphatic blends
- Some alcohols and esters (with modifications)
This makes it compatible with solvent-based and hybrid ink systems.
Gilsonite Grades for Ink Production
- Fine Powder (<100 mesh) – For black offset & newsprint inks
- Ultra-Fine Powder (<200 mesh) – For gravure and flexographic inks
- Special-Processed Low-Ash Grade – To meet high-clarity and low residue requirements
Grades are tailored for pigment dispersion and optimized flow characteristics.
Standard Packing Options for Export
We deliver Gilsonite for ink in the following packaging types:
- 25 kg paper or PE-lined bags
- 500 kg jumbo bags
- 1 MT moisture-protected jumbo bags
- Custom-branded bags available upon request
All packaging complies with international export standards.
Gilsonite’s Role in Ink Applications
Gilsonite is used in:
- Newspaper ink – fast-drying, smear-resistant
- Packaging ink – good adhesion to plastic/metal films
- Gravure ink – excellent flow and brilliance
- Offset ink – improves gloss and carbon black dispersion
- General purpose ink – economic resin substitute
How to Incorporate Gilsonite into Ink Formulas
- Pre-dispersion: Blend fine Gilsonite powder in a solvent like toluene
- Resin Phase: Replace or blend with synthetic resins
- Mixing: Use high-speed mixers to ensure even particle distribution
- Stability Check: Adjust temperature and solvent ratio for desired viscosity
The amount typically ranges from 5–25% of the total formula, depending on ink type.
Performance Benefits in Printing Inks
- Gloss Enhancement – Boosts print sharpness and black depth
- Improved Abrasion Resistance – Less smudging on contact
- Faster Drying Time – Excellent for high-speed printing
- Ink Film Strength – Better rub and scratch resistance
- Cost Efficiency – Reduces dependency on synthetic resins
Industries That Rely on Gilsonite-Based Inks
- Newspaper Publishers
- Packaging and Label Printing
- Book and Stationery Printers
- Industrial Printing Facilities
Its versatility across sectors makes it a preferred choice for mass ink production.
Shelf Life and Storage Conditions
- Shelf Life: Over 2 years in sealed containers
- Storage: Store in cool, dry areas away from moisture and direct sunlight
- Avoid: Exposure to humidity or open air for long periods
Handling & Safety Advice
- Use gloves and goggles during handling
- Avoid inhalation of fine dust
- Work in well-ventilated spaces or use fume extraction when melting
Gilsonite is not classified as a hazardous substance but should be handled with standard industrial safety protocols.
Eco-Friendly Nature of Gilsonite in Ink
Gilsonite is natural, non-toxic, and biodegradable. Compared to petroleum-based additives, it has a lower carbon footprint and can contribute to cleaner production practices in the printing industry.

FAQs
- Can Gilsonite be used in water-based inks?
Primarily used in solvent-based systems. Water-based compatibility is limited without modification. - What mesh size is ideal for offset ink?
100–200 mesh is optimal for uniform dispersion and quick drying. - Is Gilsonite better than petroleum resins in ink?
Yes, for certain applications—it offers better bonding and environmental friendliness at a lower cost. - How is Gilsonite stored during humid seasons?
Use sealed containers in a dry, temperature-controlled warehouse. - Does Gilsonite affect ink color?
It enhances black and can improve depth and sheen in dark inks but should be tested in colored formulations.
