Dupre 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 flammibilty. MicaShield products are safe and easy to use, non-toxic and enviromentally-friendly.

As it is a fully formulated product with organic adhesion promoters, DM677 only requires appropriate dilution with water prior to use. The solids content of this product, measured at 110 °C, is approximately 15.5%.
