설명

일반 설명

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.

애플리케이션

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).

특징 및 장점

Hydrolytically stable, improves flow and leveling and gives high film hardness.

물리적 형태

Dihydroxy-functional oligomer. Aliphatic urethane of proprietary composition

기타 정보

This product contains both primary and secondary hydroxyl functionality.
