Stainless steel powder is in the shape of particles. It has good corrosion resistance and durability. Its flaky particles can be positioned parallel to the surface of the coating film and distributed throughout the coating film to form a shielding layer with excellent hiding power to block moisture.

Silver Powder

Submitted by admin on Mon, 06/03/2019 - 01:16

Aluminum powder has silver-white metallic luster, so it is commonly known as ALUMINIUM-SILVER powder or silver powder. Its chemical composition is actually "aluminium", not "silver".

Aluminum powder is mainly used in powder coatings, inks, plastic masterbatches, printing, imitation gold paper, imitation gold cards, gold film, textiles, but in water-based paints and paints with acid and alkali, it will be oxidized and blackened. It is not recommended for applications requiring acid and alkali resistance and combination with rainwater.
