Water based black pigment paste for coloring

Carbon black is an important raw material for black pigment paste production. Different kinds of carbon black will bring different color hue pigment black paste, and the funtion will also be different.  Now we share some important information about carbon black and black pigment paste selection.

According to the production process of carbon black, there are furnace carbon black, tank black and so on;

According to the application of carbon black, there are rubber carbon black, ink carbon black and conductive carbon black;

Carbon black is in the form of particles, it needs to be fully moist and dispersed in the water based black pigment paste material formula. Experienced pigment paste engineers all know that carbon black is difficult to be dispersed, it needs to spend more time than other raw materials to be wet, pre-dispersing time is longer.  Oil absorption is an important indicator of carbon black, the carbon black with higher oil absorption will be smaller particle size, its specific surface area will be bigger, and more black. Of course, it is more difficult to be dispersed well.

So the black pigment paste is more black, the price is more expensive!  As the particle size of black pigment paste is fine, when the light through the black coloring layer, scattering effect of short-wave blue light will be stronger than long-wave red light. The figure is that spraying effect  on bicycle metal parts by water-based black paint, the right one is colored by CAISON 8 series water based pigment paste 8501 Black; the left one is colored by black pigment paste from another pigment paste supplier. Obviously, the right one is more black.
