Dispersion processing of high viscosity materials

When making polyurethane caulking materials, the viscosity of component B is too high when adding fillers and the dispersion is uneven. I would like to ask if any experts have any good solutions. The mixer used in our laboratory is a shear emulsification mixer with a maximum speed of 11,000r/min.

Not only in the laboratory, but also in industrial production, if you add too much filler, it is also a problem that the viscosity is too high, making it difficult to disperse.

Change the fineness of added fillers or treat fillers with surfactants

Thanks, I'll give it a try! We are contacting you to buy 400 mesh calcium carbonate powder. 4# altair77
