How Many Types Of Red Pigment Paste?

How does paint formulation engineer choose the applicable pigment paste?  This question is very complicated, because the types of pigment paste is too much. This article will introduce one kind of larger amount sold pigment pastes---red pigment paste.

Firstly, we would learn something about red pigment types, because pigment is the key material for producing pigment paste. Red pigment color paste is made by red pigments, and the characteristics of the red pigment also determines the key characteristics of the red pigment paste.

The red pigment is divided into organic red pigment and inorganic red pigment according to the structure.  Organic red pigments can be divided into azo red pigment, disazo red pigment, azo fine red pigment, heterocyclic red pigment, quinacridone red pigment, dioxazine red pigment, vat red pigment and etc ; inorganic red pigment also can be divided into molybdenum red, cadmium red, antimony sulfide, transparent iron red, natural iron red, molybdenum cadmium red, mercury sulfide, red lead (lead red) and so on.

Due to the different structures of red pigments, it has an important effect on the physical properties, chemical properties and safety parameters of red pigment pastes. So the paint formula engineers will always ask the pigment paste manufacturer s for red pigment color index, in order to know whether the pigments performance meets their application requirement.

Here we introduce some main red pigments on the market, pigment C.I. number is international common pigment color index. paint formulation engineers and pigment paste engineers can learn the red pigment performance based on the pigment color index:

C. I. Pigment Red 176, C. I. Pigment Red 258, C.I. Pigment Red 179,

C.I. Pigment Red 178, C. I. Pigment Red 104, C. I. Pigment Red 101,

C. I. Pigment Red 112, C. I. Pigment Red 149, C. I. Pigment Red 254,

C. I. Pigment Red 276, C. I. Pigment Red 277, C. I. Pigment Red 3,

C. I. Pigment Red 52: 2, C. I. Pigment Red 53: 3.

Red pigment paste can be produced by different types red pigments, and sometimes some types red pigments are mixed to produce red pigment paste.  Coatings formula engineers should select the right red pigment to manufacture red color pigment paste.
