Equipment Guidance
The SDF400 Laboratory Disperser handles high-shear dispersion and homogenisation. It is used for Architectural Paints, Printing Inks, Industrial Coatings, normally ahead of milling or filling.
It handles viscosity up to up to approximately 20,000 cP. Product-contact parts are Stainless steel 304 / 316L.
The sawtooth or rotor-stator head breaks agglomerates and wets out powder into the liquid phase. Final dispersion quality is confirmed by a material trial.
Capacity is 0.5 - 20 L with motor power 0. Models cover batch and in-line duties depending on the process route.
Batch dispersion suits multiple products and frequent changes; in-line dispersion suits continuous or high-volume single products. POLYC recommends after reviewing your route.
