Specialty coatings containing vermiculite are made from dispersions after the mineral has been finely delaminated, either chemically or physically. Vermiculite dispersions are used in high-temperature coatings or binders for:
- Construction materials
- Weld curtains
- Specialty papers/textiles
- Oxidation resistant coatings on carbon composites
- As barrier coatings for films
When combined with other fillers, milled exfoliated vermiculite and a ‘paint type’ binder can be used as a wet spray-applied anti-drumming compound. These products are used extensively to dampen the vibration of architectural panels, like those used in curtain wall construction or as claddings in railway stations and tunnels.
