{wiki=Polyurethane_dispersion}
Polyurethane dispersion (PUD) is a type of polymer material that consists of polyurethane particles dispersed in water or another solvent. It is created through a process that typically involves the emulsification of a polyurethane prepolymer in water, often using a surfactant or other stabilizing agents to maintain the dispersion. \#\#\# Key Features of Polyurethane Dispersions: 1. **Water-Based**: Unlike traditional polyurethane formulations that may contain organic solvents, PUDs are primarily water-based.
