Dispersing Agents for Solvent Based Systems

Dispersing agents are used extensively in the coatings industry to help disperse solid particles into a liquid medium.
Dispersing agents perform by the anchoring of the surfactant onto the particle substrate and then acting as a barrier to stop re-agglomeration of the particles. This concept is often referred to as steric stabilisation. The new hyperdispersant has three functions, firstly a powerful amine anchoring group that latches onto the pigment substrate, secondly a tail section that floats within the solvent medium and thirdly a capping group that further enhances steric hindrance between pigment particles.
