Wetting and Dispersing agents

Wetting and dispersing agents

Dispersing agents playing a very important role for the wetting and stabilization of pigments.
The faster the wetting is taking place the faster the stabilization can take place. in this process it is important to be able to reduce the particle size back to the primary particle of the pigment. Than you will achieve the maximum color strength. Very good dispersing agents will offer you very good viscosity reduction, color strength, transparency, reduction in processing time. UNIQCHEM offers a full range of different chemistry of wetting and dispersing agents, low molecular weight to very high molecular weight.
