摘要：
Amide modified saturated polyester polyols having an acid number of from about 0 to about 27, a hydroxyl number of from about 12 to about 360 and an amine number of from about 0.1 to about 6.5 are disclosed. The amide modified saturated polyester polyols are useful as part of a two-package urethane coating system.
