Why Add Gilsonite to Paint?
If you’re in the paint or coatings industry, you’re likely looking for ways to improve durability, gloss, and chemical resistance. One additive that does exactly that is gilsonite. This naturally occurring bitumen is becoming increasingly popular in paint manufacturing—and for good reason.
Gilsonite for paint acts as a powerful binder and performance enhancer. It strengthens coatings, boosts water and chemical resistance, and improves adhesion to various surfaces.
At Basekim, we supply high-quality gilsonite tailored specifically for the paint and coatings industry. With consistent particle size and purity, our gilsonite helps manufacturers achieve superior results—without adding unnecessary cost.
What Is Gilsonite?
Gilsonite is a natural, solid hydrocarbon. It’s also called natural asphalt or uintaite. Found mostly in the United States and the Middle East, gilsonite is mined in its solid state and then crushed into fine powder for industrial use.
Chemically, gilsonite is rich in carbon and hydrogen, and it has a unique molecular structure that allows it to dissolve in aromatic solvents and certain oils. Because of this, it blends easily with paint resins, alkyds, and other binding agents.
How Gilsonite Enhances Paint and Coatings
Adding gilsonite to paint formulas can significantly boost their performance. Let’s explore the main benefits:
✔ Increases Hardness and Durability
Gilsonite improves the abrasion resistance of paint, making it ideal for surfaces that experience frequent contact, like floors, industrial machinery, or fences.
✔ Improves Water and Chemical Resistance
Paints with gilsonite resist moisture, salt, acids, and chemicals better than standard formulations. This is especially useful in marine coatings, pipes, and chemical storage tanks.
✔ Boosts Gloss and Black Color Depth
Gilsonite has a natural jet-black color and high gloss potential. When used in dark paints or primers, it deepens the color tone and improves visual appeal.
✔ Enhances Adhesion
Because of its natural binding ability, gilsonite helps paint stick better to metal, concrete, and wood surfaces. This means fewer re-coats and longer-lasting results.
✔ Reduces Cost of Formulation
Since gilsonite is a natural and cost-effective additive, it can replace part of more expensive resins or binders—without sacrificing quality.
Common Paint Applications for Gilsonite
Gilsonite is used in several types of paints and protective coatings:
Industrial and Protective Coatings
In factories and construction sites, surfaces need tough protection. Gilsonite-enriched paints provide resistance to wear, chemicals, and weathering.
Marine Paints
Saltwater, UV rays, and moisture demand a strong barrier. Gilsonite-based coatings are popular for ship hulls, docks, and offshore structures.
Tank and Pipe Coatings
Storage tanks and pipelines need paint that resists corrosion and chemical spills. Gilsonite strengthens these coatings for longer life.
Foundation and Concrete Sealers
Gilsonite improves penetration and bonding to concrete. As a result, it’s often used in waterproof coatings and sealers for basements and foundations.
Black Primers and Bituminous Coatings
Because of its black color, gilsonite is ideal for black primers, bitumen-based paints, and rust-proofing agents.
How to Use Gilsonite in Paint Formulation
Using gilsonite in paint production is straightforward, but the particle size and compatibility must be correct. Here’s a general guideline:
Choose the Right Grade
Gilsonite comes in various mesh sizes. For paint, fine powders like 200 mesh are preferred for smooth blending.Dissolve in Compatible Solvents
Gilsonite dissolves in aromatic solvents (like toluene, xylene) and blends with alkyd resins. Always test for compatibility before large-scale mixing.Add to Resin or Binder Phase
Incorporate gilsonite during the resin phase of your formulation for even dispersion.Mix and Filter
Blend the mixture thoroughly and filter to remove impurities. This ensures a clean, smooth final product.
At Basekim, we help our clients choose the right gilsonite grade for their application and provide technical guidance throughout the process.
Safety and Storage Tips
While gilsonite is a natural product, it still requires safe handling. Follow these simple tips:
Store in a dry, cool place, away from open flames
Use dust masks and gloves when handling powdered forms
Ensure good ventilation during mixing and application
Always review the Material Safety Data Sheet (MSDS) before use
Basekim supplies gilsonite in moisture-proof bags and drums to preserve quality during shipping and storage.
