聚氨酯二醇溶液（PUD）是一种合成的聚合物溶液，可用作修饰剂，通过异氰酸酯和多元醇缩合而成。 它修饰水溶性树脂和乳化液，可用于汽车涂料应用。 组成：urethane, 37% 浓度：88 wt. % in H2O 折射率：1.47 粘度：8,000 cP(25 °C)(lit.) 酸值：0.6 mg KOH/g(dry basis) 羟基值：350 mg KOH/g(dry basis) 溶解性：H2O: soluble 密度：1.14 g/mL at 25 °C 应用 PUD可用于控制银（Ag）墨水的附着力，这种银墨水打印后可以形成透明的导电电极。这些打印的电极可用于有机太阳能电池（OSC）的制造。它也可用作染料敏化太阳能电池（DSSC）的电解液。用作水溶性树脂的调节剂，以及木材、家电和汽车涂料中的乳液。 外形 二羟基官能化低聚物。具有专用组成的脂肪族聚氨酯 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.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).
