polyurethane dispersion - wikipedia
Polyurethane dispersion, or PUD, is understood to be a polyurethane polymer resin dispersed in water, rather than a solvent, although some cosolvent may be used.
fundamental insight into anionic aqueous polyurethane dispersionsThe term Polyurethane Dispersion (PUD) describes a PU dispersed in a suitable solvent for coating applications. When the conventional solvents are replaced with water owing to its green nature, we get Aqueous Polyurethane Dispersions (APUD).
polyurethane dispersion | formula, properties & applicationPolyurethane dispersion, often referred to as PUD, is a high-performing class of polyurethane resins that have found extensive applications in several industries due to their versatile properties.

polyurethane dispersion - an overview | sciencedirect topicsPolyurethane dispersions (PUDs) are urethane polymers finely dispersed in water that are used both in waterborne one-component formulations and increasingly also in two-component systems.
recent developments in waterborne polyurethane dispersions ... - springerWaterborne polyurethane dispersions used in surface coatings have recently gained a lot of interest as the need for more and more alternatives in the case of chemical components has arisen. Nevertheless, WPUDs can be used to obtain coatings with superior qualities.
introduction to polyurethane chemistry - acs publicationsIntroduction. Polyurethanes are an immensely versatile class of polymers used in insulators, foams, elastomers, synthetic skins, coatings, adhesives, and so forth. Polyurethane was first developed through basic diisocyanate polyaddition reactions by Dr. Oto Bayer and partners (1).
