Top 10 Uses of Gilsonite in Industry

Gilsonite appears in an impressive number of products. Here are the ten most important industrial uses.

1. Drilling fluids

Fine gilsonite seals micro-fractures and pores, reduces fluid loss and stabilizes shale. See drilling fluid grade gilsonite.

2. Oil well cementing

Added to cement slurries, it lowers density, improves bonding and helps stop gas migration.

3. Asphalt paving

A few percent of gilsonite makes asphalt binder stiffer and more rut-resistant.

4. Foundry sand

Gilsonite releases gas during casting, creating a clean surface on iron and steel castings.

5. Printing inks

In black news and publication inks, it acts as a resin and colour enhancer.

6. Paints and varnishes

It gives deep black colour, gloss and chemical resistance in industrial coatings.

7. Pipe coatings

Gilsonite-based enamels and mastics protect buried steel pipes from corrosion.

8. Waterproofing

Roofing compounds, foundation coatings and membranes benefit from its water resistance.

9. Sealers and fillers

Pavement sealers, crack fillers and joint compounds use gilsonite for hardness and durability.

10. Additives and blends

It is used in rubber compounding, adhesives, briquetting binders and many specialty blends.

Each application uses a slightly different grade. Our gilsonite powder covers most needs, while micronized and granular grades serve specialty markets. Explore gilsonite grades and mesh sizes to find the right fit.
