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