Gemme Micron, a nano-fine barium-sulfate-based functional additive permits innovative potentials for the optimization of paint properties.

Gemme Micron, a nano-fine barium-sulfate-based functional additive permits innovative potentials for the optimization of paint properties. A special production process combined with extremely effective after-treatment (coating) guarantees extreme fineness and the product's low conductivity at consistently high levels.


Thanks to Gemme Micron's small particle diameter of less than 0.3 μm and its low refractive index, no loss of transparency or gloss in the coated surface occurs. On the contrary: The spherical geometry of the Gemme Micron particles means that gloss is actually enhanced in most cases. Gemme Micron is used for stabilization of organic and inorganic pigments against flocking. Gemme Micron adsorbs on the surface of the pigment and thus prevents agglomeration of the pigment particles. This stabilizing mechanism can be attributed on the one hand to purely steric effects and, on the other hand, this repelling action can also be explained by the electrostatic charge carried on the surface of the Gemme Micron. The use of Gemme Micron B-30 in particular permits effective improvement of the orientation of the aluminium flakes in metallic-finish paints.


This product's low binder requirement makes it possible to use Gemme Micron to precisely control the rheological properties of a paint or coating. Gemme Micron additive permits formulation of haze-free high-gloss paints, water-based paint systems, and paints and coatings with a high solids and low solvent content. The addition of a number of percentage points of Gemme Micron reduces the solvent content of the paint system significantly. An increased solids content in a paint reduces the readily-volatile solvents content significantly, thus contributing decisively to the achievement of a lower pollution burden for humans and the environment.
