Specialty Coatings

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
• Gaskets
• 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.
