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.
