DM675

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.


The solids content of DM675, measured at 110 °C, is approximately 17.5 %. DM675 usually requires appropriate dilution with water prior to use; although DM675 is partially formulated with organic adhesion promoters, additional additives may need to be included in the final coating recipe.



WHY USE MICASHIELD DM675?

  • Protective coating for Fibre Glass Textiles
  • Flame and Heat Protective Barriers
  • Specialist Films/Coatings



HOW TO APPLY MICASHIELD

  • Conventional industrial textile coating techniques.
  • Dilute with de-mineralised water to the appropriate solids content for the level of coating required; a commonly used dilution is: 65 % DM675 to 35 % water and additives.
  • It is the user’s responsibility to establish the correct dilution for their process / application.
