Aluminium powder 7 µm "MillEx-H", flake-shaped, stabilized

Product information "Aluminium powder 7 µm "MillEx-H", flake-shaped, stabilized"

Thanks to a special manufacturing process, this aluminum powder, despite its extremely small particle size, is not classified among the dark varieties such as German Dark (5413HS), Chinese Dark or Indian Dark.

The otherwise common addition of carbon in the form of graphite has been omitted. In return, however, the fatty acid content is higher. This makes this aluminum powder very suitable for applications as a silver metallic pigment or screen printing ink, even though reactive properties were the focus during development.

Compared to the dark aluminum powders mentioned, MillEx-H has approximately 50 to 60% lower bulk density.

As a pigment, it demonstrates the highest opacity of all our aluminum powders, with the gloss being slightly lower due to the small particle size. It is classified as a leafing pigment.

Brass powder, 9μm, Rich gold, flaky / flaky-shaped, Metallic Pigment, stabilized
pack size: 1,0kg

This Brass powder ist speziell für optische und funktionelle Anwendungen hergestellt worden. Es wurde 1,5 % stabilized with 1.5% oleic acid.In der plastics processing erzielt es herausragende Effekte bei HDPE, LDPE,ABS oder gar PVC. Gerade in diesem Bezug sollte bei der Fertigung von masterbatches darauf geachtet werden, dass das Pulver nur geringstmöglichen Scherkräften und Verweildauern bei hohen Temperaturen ausgesetzt wird. Beide Faktoren könnten sonst das optische Endergebnis negativ beeinflussen. Ebenfalls ist dieses Pulver bestens auf den Einsatz in Farben/Lacken/2K-Harz und screen-printingverfahren abgestimmt. Bereits ein Verhältnis von 5/100 (Pigment/Bindemittel) ist für ein optisch hochwertiges Ergebnis ausreichend. Sie erhalten einen beeindruckenden gold-metallic effect - die Oberfläche sieht anschließend wie ein polished brass sheet aus. Please observe the following during processing: screen-printing: The mesh size should be three times larger than the powder D90 value. aerosol spray cans: The powder D90 value should be at least three times smaller than the nozzle diameter. coatings/paints: Avoid mechanical stress from very fast-running agitators. This would damage the particles and destroy the metallic effect.

This copper powthe is specially designed for optical and functional applicationsdeveloped and manufactured worden. This is pure copper, which has been stabilized with 1,5 % oleic acid. In Kunststoffverarbeitung produces outstanding effects in HDPE, LDPE,ABS othe gar PVC. In this context should during the Fertigung of Masterbatches care must be taken to ensure that the powthe nur geringstmöglichen Scherkräften and Verweildauern during hohen Temperaturen ausgesetzt wird. Beide Faktoren könnten sonst the optical Endergebnis negativ beeinflussen. Ebenfalls is this powthe bestens auf den Einsatz in paints/coatings/2K-Harz and screen-printing processes abgestimmt. A ratio of 5/100 (Pigment/Bindemittel) is for ein optisch high-quality result . This produces an impressive copper-metallic effect - the surface sieht anschließend wie ein polished copper sheet aus. Bitte beachten Sie during the processing: screen printing: Maschenweite should drei mal größer als the D90-Wert des powders sein. Aerosol spray cans: Der D90-Wert des powders sollten mindestens drei mal kleiner als the Düsendurchmesser sein. Lacke/paints: Mechanische Einflüsse durch sehr schnell drehende agitators avoid. Dies würde the Partikel beschädigen and den Metallic-Effekt zerstören.

Aluminum powder 70 µm, flake, stabilized
pack size: 500g

This aluminium powder is made in Germany. A previously produced aluminum spray grit is ground in ball mills with the help of fatty acids . Here the primary particles undergo a change in size, but more importantly a change in shape. The resulting particles are now platelet-shaped and act like tiny mirrors.The powder is therefore an excellent metallic effect pigment for varnishes, paints or, more recently, screeds. Preferred areas of applicationFiller in polymer processing (2K systems, fillers, varnishes, paints)Aerated concreteChemical reducing agent / gas generatorsPyrotechnicsTypical analysis valuesFormula: AlActive metal content: 93.2%Sieve residue: 0.1% (at 45µm)Acetone-soluble components: 1.7%Wetting on water: 9260cm²/gParticle shape: platelet-shaped (flaky)CAS No.: 7429-90-5Signal word: ATTENTION!
