Nubifer Y-7050 - A heat-resistant Yellow Iron Oxides
Yellow Iron Oxides are not heat resistant and can only be used below 180ºC-190ºC. At such temperature, the goethite structure of the Yellow Iron Oxides turns into the hematite structure characteristic of the Red Iron Oxides. Therefore a color change from yellow to red is clearly observed.
The way to prevent such color fading is to protect the Yellow Iron Oxide structure with an encapsulation to withstand high temperatures (260ºC, 5 min), allowing its use in Plastics.
The encapsulation, specially developed by Nubiola, is made of inorganic compounds only and guarantees high compatibility with any polymers in all sort of Plastic applications.
Moreover, Nubifer Y-7050, being a Yellow Iron Oxide, shows all the excellent attributes which are characteristics of such range of pigments.
As well as our Nubifer K Series Zinc Ferrites, Nubifer Y-7050 can be used as a replacement for Pigment Brown 24 (PBr24) and red organic pigments both in Plastics and high temperature cured Coatings. This substitution allows formulating beige, green, red and brown color shades at reduced cost keeping the same chemical and physical properties, therefore, Nubifer Y-7050 and Nubifer K Series are cost-efficient high performance solutions for Plastics and high temperature cured Coatings
