Abstract:
Polyurethane systems that cure similarly to systems based on mercury catalysts contain 1,4-butanediol and a zinc carboxylate catalyst. These systems cure and develop green strength similarly to systems based on mercury catalysts. These systems are especially useful in making insulated pipe joints for subsea pipeline installations.
