SS316L Inline High Shear Homogenizer for Waterborne Polyurethane Dispersion and PU Prepolymer Emulsification

Vison Chemicals designs and builds SS316L inline high shear homogenizers for the production of waterborne polyurethane dispersion (PUD) and the emulsification of PU prepolymer into water. The rotor-stator workhead applies intense mechanical and hydraulic shear to break the hydrophobic polyurethane prepolymer and isocyanate-terminated chains into a stable aqueous dispersion with fine, uniform particle size. The result is a low-VOC polyurethane dispersion used as a binder in waterborne coatings, leather finishing and textile coatings. Modular units scale from 0.5 to 30 m3/h for pilot and full-scale PUD production lines.

Key Features

• Rotor-stator high shear workhead reduces polyurethane dispersion particle size to 1-5 micron for a stable, long-shelf-life PUD
• SS316L wetted parts with double mechanical seal suit waterborne polyurethane dispersion and PU prepolymer emulsification duty
• Variable frequency drive from 0 to 2900 rpm controls shear intensity for batch-to-batch reproducible dispersion quality
• Modular inline design integrates into the PUD production reactor loop for continuous prepolymer emulsification and chain extension
• Optional explosion-proof motor for solvent-assisted polyurethane dispersion processes
• CIP-compatible construction eases cleaning between waterborne coating and leather finishing dispersion batches
