Controlled Oxidative Curing of Tung Oil

摘要

Antiskinning agents are used to control the oxidative curing of tung oil catalyzed using a cobalt drier.Additives agents that are too volatile result in the premature formation of a cured oil (e.g.,shin),whereas antiskinning agents that are usKRv to release from the fatty oil may delay drying altogether.Methyl ethyl ketoxime is currently the most popular antiskinning agent;but due to its relatively high volatility coupled with associated health hazards,new antiskinning agents are being ;sought for aqueous and solvent-based alkyds.In this article,new formulations containing an antiskin agent and a co-promoter to activate the metallic drier,providing excellent antiskinning performance while providing improvement in dry-through performance,are presented.
