Off-Color Barytes

In many applications, dry grounded off-color barytes can be an economical alternative to white barytes with a high brigthness. These products are the perfect solution for all applications non-critical in regard to color, but still requiring a controlled particle size distribution and a guaranteed high density.

Range of use:

Sound insulation (construction and plastic industry), friction pads and clutch linings, drilling industry,  floor linings, mastics, joint sealer and sealents, pigment preparations, plastic, rubber, adhesives, glass and polishing agents, radiation protection (medicine and nondestructive testing), paints

White Barytes

The white barytes offered by Sachtleben Minerals GmbH & Co. KG are characterized by a high brightness and a guaranteed low yellowness. They are color neutral due to their low refractive index. They hardly contain calcium carbonate, offer a low electrical conductivity and guarantee a low binder demand. Due to their low silica content they hardly cause any abrasivity, what results in decreasing maintenance costs and increasing equipment life times.

Range of use:

Paints, floor coverings, filler and pigments, pigment preparations, primers and putties, adhesives,   plastic, rubber, glass and polishing agents.

Albawhite

Dry grounded white Barytes, produced from sorted raw materials with extremely low silica and iron contents.
L* (powder) > 96

Range of use

Albawhite-grades are favourable used in fillern, primern and putties and due to the high brightness in topcoats and pigment preparations as well. They are also excellent suitable for anti-corrosive paints. The Albawhite-grades increase the hiding power of a standard powder coating and provide for a partial pigment replacement.

Albawhite 10 can be used for the matting of various powder coating qualities. The matting effect was tested in a hybrid-system (60/40) as well as in a PUR-system. Albawhite 10 can be inserted easily and straightforward. The concentration of barium sulfate applied was 30 weight-%. Depending on the system it is possible to achieve a gloss level below 70 at 60°. Albawhite 10 is suitable for co-extrusion processes very well.

Albawhite 80 and Albawhite 90 are used for high gloss finished topcoats with outstanding mechanical properties favourably. Due to the high purity level, these grades are guaranteed colour neutral. In thermoplastic resin both grades can be used as a filler for synthetics with high gloss finished surfaces

Albawhite H90

This finely powdered quality is easy to disperse and provided with an hydrophobic character

Albawhite 100 will enhance the mechanical and optical properties as well as the gloss positively. It is excellent suitable as a filler for elastomer. We highly recommend Albawhite 100 for the colour matching of thermosetting plastics.

Fleur/EWO

EWO (wet grounded white barytes): produced of best raw materials by chemically bleaching up to a guaranteed high brightness. EWO can be used as an absolutely colour stable alternative to synthetic barium sulfates. This product is characterized by its stable brightness, its chemically resistance and the high purity.

FLEUR can be a commercially interesting alternative to EWO. Both products are guaranteed free of calcium carbonate.

L* (powder):  Fleur > 96, EWO: > 97

Range of use:

Due to the high purity level of EWO this product is favourably used for top-quality primers, anti-corrosive and latex paints, in putties, pigment preparations and floor coverings as well. EWO increases the hiding power in standard powder coatings and provides for a partial pigment replacement.
The product is widely used in plastic and rubber: for plastic it is used as a color-neutral and chemically resistant filler.
The unique production process for EWO guarantees a low yellowness and therefor the product can be used for colour-sensitive systems with a high long-term stability (e.g.: PVC-films and joint sealings). EWO has an outstanding dispersability in plastisol and UP-resins. Due to the low coarse grit-level superior synthetic surfaces are achievable.

Albasoft/Albasoft 90/Albasoft 100

Wet grounded white barytes: produced of selected raw materials by chemically bleaching up to a guaranteed premium high brightness. Specially dedicated to applications with high requirements to gloss. Therefor we produce finely grounded specialties which be characterized by their narrow particle size distribution.
L* (powder): > 97

Range of use:

Utilizing Albasoft-grades will enhance the mechanical and optical properties as well as the gloss positively. The products increase the hiding power of a recipe and allow pigment replacement partly. They are highly suitable as a filler for elastomer.
Albasoft is used in topcoats, fillern and pigment preparations favourably. It is typically also used in plastic.
Albasoft 90 and Albasoft 100 are favourable used for top-quality powder coatings, high gloss finished topcoats, in fillern and pigment preparations as well. In thermoplastics both can be used to partially replace color pigments in masterbatches.
