摘要: Scavenging moisture from a polyisocyanate useful for preparing thermosetting polyurethane coatings therefrom is accomplished by admixing with the t-butylated hydroxytoluene and an alkyl ester of toluenesulfonic acid in which comprises at least 90% para ester, thereby improving shelf life polyisocyanate.
