Hyperdispersant - UV and LED Cured Systems

Quick Links

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:

  • A powerful amine anchoring group that latches onto the pigment substrate

  • A tail section that floats within the solvent medium

  • A capping group that further enhances steric hindrance between pigment particles. Lansperse UV51 has been specifically designed to offer optimum performance in monomer systems commonly used in UV formulations.
