Dispersing agents form an essential part of a pigmented coating formulation. Their use would generally improve grinding efficiency, color development, transparency and gloss.
But the physical properties of the coating layer can be compromised.
Efka PX 4780, Efka PX 4785 and Efka PX 4787 have been specifically designed to alter this dynamic. When cross-linked with the main resin matrix, these high-performance dispersing agents offer excellent dispersing efficiency and significantly improves coating properties, such as solvent resistance and hardness.
Other benefits include improved gloss and exceptional jetness with carbon black pigments.
