5/1/2023 0 Comments Dispersio n![]() Our article on grading explains the different phases that make up the dispersion process: wetting, deagglomeration or actual dispersion, and stabilisation. These issues include phase separation, sedimentation, loss of gloss, greater viscosity or heterogeneous colour, which indicate issues in the dispersion phase of the manufacturing of such paint. When the dispersion process has not been carried out correctly, the finished product may show a series of issues after a certain storage time has elapsed. Some examples are the Supermill, Mill-ennium or Optimill equipment. Microelement mills that achieve higher dispersion degrees.A great example of which are the O+B Dispermix High-speed blade agitators which provide the dispersion needed for manufacturing plastic paints.Special mechanical equipment is used to achieve the desired goal in an efficient way, such as: One of the most important features to consider in the dispersion process is the need to combine and stabilise materials that, in many cases, are incompatible: pigments, additives of different chemical nature, water, etc. Market, use, and application of the paint will also be taken into account. The goal in the dispersion phase is to cause most of the agglomerated pigments and fillers that are part of the formula to be stably separated as individual particles.ĭepending on the properties desired for the paint being manufactured (colour, coverage, gloss, etc.), the amount of particles separated by the dispersion process shall vary. When it comes to emulsified paints, for example, it is widely considered as the most important phase. ![]() ![]() Dispersion is a key phase in paint manufacturing. ![]()
