Transparent Iron Oxide

Transparent iron oxide pigment is known as nanometer iron oxide pigment with primary particle size less than 100nm and typical specific surface area of 80 – 120m2/g.

  • Product Description

Transparent iron oxide pigment is known as nanometer iron oxide pigment with primary particle size less than 100nm and typical specific surface area of 80 – 120m2/g. Because its size is smaller than wavelength of visible light (320 – 750nm), diffraction occurs in light irradiation and coating shows transparency property.

Usage:

Transparent iron oxide pigments can be used in automotive coatings, wood coatings, architectural coatings, industrial coatings, powder coatings, art paint, plastics, nylon, rubber, printing ink, cosmetics, tobacco packaging and other packaging coatings.
Transparent iron oxide pigments can be used in combination with organic pigments which can not only enrich the color and improve the chroma, but also can significantly improve the condition of poor weather resistance when organic pigments are used alone.
