Dispersing agents are used extensively in the UV coatings industry to help disperse solid particles into the UV medium, either UV monomers or oligomers.
​
Dispersing agents perform by anchoring the surfactant onto the particle substrate and then acting as a barrier to stop the 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 surface, secondly a tail section that is compatible with the UV medium and thirdly a capping group that further enhances steric hindrance between pigment particles.

Modifications to raw materials give a product with improved fluidity.
