EMPEROR 1800 provides formulators of base-coats for automotive and other high-colour applications with high-black colour performance, rapid and economical dispersion and long-term performance stability.
Cabot was the first carbon black supplier to develop black pigments specifically for water-borne applications, and the new product underlines the company’s commitment to remain the leader in this sector. Like the existing EMPEROR 2,000 pigment, the new product consists of small-particle carbon black that is chemically modified in order to attach specific functional groups to the pigment surface. As a result, the pigment is fully compatible with water-borne systems and delivers better performance than conventional oxidised carbon black pigments.
The surface treatment allows the pigment to disperse to individual aggregates, resulting in a black colour that is superior to other comparable products currently on the market and provides a combination of high jetness and deep blue undertone. Colour is very consistent because the variability caused by dispersion quality variation is also reduced.
EMPEROR 1800 disperses quickly and easily as a result of electro-static stabilisation in aqueous solutions, which causes the pigment particles to automatically separate during production and remain separated afterwards.
As a result, grinding times are shortened and the quantity of dispersion additives required to achieve optimum performance can be considerably reduced – typically by more than 50 per cent – compared with conventional oxidised carbon black.
Owing to the stability of the pigment, shelf life of mill-bases and final formulations in which it is used is greatly extended and final film properties are consistently maintained.
