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 maybe used.
polyurethane dispersions - lubrizolPolyurethane Dispersions. Polyurethane dispersions are resins supplied in water that bring a unique combination of toughness, mechanical properties and durability typically not achievable in other polymer chemistries. These resins are used on a wide range of surfaces and applications, including wood, metal, plastics, masonry and textiles.
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).
