General description
Polyurethane diol solution (PUD) is a synthetic polymeric solution that is used as a modifier that is formed by condensation of isocyanates and polyalcohols. It modifies water soluble resins and emulsions which can be used in automotive coating applications.
Application
Modifier for water-soluble resins and emulsions in wood, appliance and auto coatings.
PUD may be used to control the cohesion of silver (Ag) inks which can be printed to form transparent conducting electrodes. These printed electrodes can be used in the fabrication of organic solar cells (OSCs). It may also be used as an electrolyte for dye sensitized solar cells (DSSCs).
Features and Benefits
Hydrolytically stable, improves flow and leveling and gives high film hardness.
