Barium sulfate: For perfect coatings
Nowadays, automotive paints have to be genuine all-rounders. They not only need ideal optical characteristics, they must also provide protection and be mechanically and chemically stable. Our Blanc fixe products provide the optimum basis for all these requirements.In the medical field, Blanc fixe XR used as a contrast agent not only permits X-ray examination of the gastro-intestinal tract; in X-ray opaque plastics, as used for catheters, drainage tubes and hypodermic cannulae, X-ray barytes incorporated as an additive into the raw plastic compound is able to render such implants visible on the X-ray screen.
Thanks to their high density, low Mohs' hardness and low binder demand, natural barytes are suitable for a broad range of diverse applications in plastics and also in the paints and coatings industry.
As a functional additive based on an extremely fine-particled synthetic barium sulfate, Sachtoperse opens up innovative potentials for optimization of the properties of plastics and paints. The specific nature of the Sachtoperse particles permits this product's use as a nucleation agent for PET plastics, for efficient deflocculation of colored pigments and for reduction of the solvent content in paints and coatings.
