DUPRÉ Minerals’ Micashield is a stable, water based, dispersion of high aspect ratio platelets produced by the controlled exfoliation of specially selected vermiculite ores; vermiculite is the name given to a group of hydrated laminar aluminium-iron-magnesium silicate minerals.

The Micashield product range offers temperature resistant coatings up to 1100 °C that are non-flammable (unformulated) or, for formulated products incorporating organic additives, of limited flammability.

Micashield products are safe and easy to use, non-toxic and environmentally-friendly. They are commonly used to coat glass textiles where they are the main constituent of the cloth finish along with organic adhesion aids and water to control the viscosity.

DM382 is a highly beneficiated vermiculite product with the addition of an organic adhesion aid.
