Product Description

YELLOW 3420/3422

Special AttentionRegular iron oxide yellow has limited heat stability, decomposing at

However, withourThermoxideIronYellow pigments, the heat stability has drastically increased to the range between
240~ 265

ThermoxideIronYellow3420/3422 uses an inorganic after treatment (silica & aluminum oxide) to encapsulate regular iron oxide yellow to achieve the heat stability of 240~265.  

Thermoxide Yellow Color Shade

The particle shape is acicular/elongated and can be clearly seen under the electronic microscope (see picture onbelow).

Compare with Bayferrox 3920 and Y-20


Thermoxide Yellow 3420/3422 Attributes¼
  • High Heat Resistant specific grades are stable over240C which makes the most temperature demanding applications possible.
  • Environmental withSGS certification, the major heavy metals are not detected in our products to comply with safety and environmental requirements.
  • High lightfastness / weatherfastness the chemical structure of iron oxides carries in itself the high light fastness / weather fastness resistance.
  • Micronized for ease of dispersion micronized through air-pressure pulverization process, the ease of dispersion can also help increase productivity.
  • Cost effectiveness with the above product features, there are no other products available in the market at this price value.

Main Applications:
Due to ultra high weather resistance and over 240 degrees of temperature resistance,itwill be amost optimal value of the application direction fortheoutdoor artificial grass coloring above.

Outdoor wood plastic products.

Extruded sections
Many section masterbatch pigment has high weatherability requirements, this is the application of the strengths of yellow envelope.
