Polyurethane-58

Čo to je?

Polyurethane-58 is a complex polymer made by reacting polytetramethylene ether glycol, 2,2-dimethylolpropionic acid and meta-tetramethylenexylenediisocyanate to form a prepolymer. The prepolymer is dispersed in water with 2-dimethylamino-2-methylpropanol as neutralizer and chain-extended with ethylenediamine.
