Aqueous Vermiculite Dispersion (DM160)

Description

Dupre Dispersion can be used to provide a fire or temperature resistant coating onto a variety of substrates including woven fabrics. It is formed by the chemical exfoliation of Vermiculite and the tiny platelets which are produced will overlap and adhere to themselves without the use of organic binders giving rise to an impermeable layer. These layers can also be created for use in the production of thin films.
