文章

Redi-Dri™ prevents hygroscopic powders, such as inorganic salts, from absorbing moisture and forming clumps, leaving the salts free-flowing every time.

Questions

  1. What is the particle size of RDD007? The website states that it is a powder and that it is free flowing.

    1 answer
    1. The exact particle size of RDD007 is not available. The description of it being a powder and free-flowing indicates that the powder is allowed to pass through a mesh to remove large solids, and only the portion that flows through the mesh screens is utilized. However, the specific mesh screens used are not documented.
