IR reflective Pigment C.I.77428 copper chromite black spinel PBK28 for ceramic and paint

Mixed metal oxide pigments offer a multitude of benefits for the coatings formulator, including excellent outdoor durability, chemical resistance and heat stability.

Mixed metal oxide (MMO) pigments, also known as complex inorganic color pigments (CICPs), have been around since the early 1800s. Their use in the ceramic and pottery industries is well known due to their overall inertness, which contributes to outstanding heat, chemical and UV resistance. The use of MMOs in industrial coatings is less common and more for special purposes. This paper will discuss the benefits of formulating coatings with MMOs as a replacement for, or in conjunction with, the more common organic types.


Heat Resistance
The thermal stability of MMOs is well known in the ceramic and pottery industries. This class of pigments is processed for hours at temperatures ranging from 800 to 1300 °C in their manufacture. Consequently, they are chemically and color stable at these temperatures in service. As mentioned, the ceramic industry has used mixed metal oxides for color glazes for centuries. The glazes used in ceramics are regularly fired at temperatures of 985 to 1300 °C (1800 to 2350 °F) without significant color shift. The use of MMOs in thermally stable coating formulations such as those based on silicone (polysiloxane) resins brings a palette superseding the traditional black and silver high-heat choices. This brings an attractive array of color possibilities to the designer of specialized and sport transportation such as motorcycles, ATVs and jet skis.

1. May I have sample to test?
----Yes, we can offer you free sample, and you pay for the shippment.

2. Why colors are not the same to powder pigment color?
----Calcination temperature, Allocation proportion of ceramic & pigment, these two factors may lcaused color difference. Usually, factory producing formula are different, so even the same factory, may produce different cobalt blue pigment.

3. Could I be you agent?
----We warmly welcome a experieced trading company to be our agent in his area.
