Carbon black Powder in the application process must be dispersed to the composite optical properties of the microparticle state, so the dispersion of carbon black will affect some other indicators of carbon black, such as colour, blackness, etc., which may affect the user’s experience.
Carbon Black Powder is better dispersed and finer than granular carbon black. This results in more contact points between the carbon black aggregates, which does more work for the dispersion to separate the carbon black particles and ultimately achieve the highest blackness and colouration.
The dispersion of carbon black is affected by the degree of structure, the better the dispersion the better the colouring strength. Carbon Black Powder is easy to disperse in paint, so the colouring effect is a little better.
