คำอธิบาย

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.

Physical form

Dihydroxy-functional oligomer. Aliphatic urethane of proprietary composition

Other Notes

This product contains both primary and secondary hydroxyl functionality.
