Has there been any testing completed on common Tung Oil finishes to determine the % content? Or can we tell based on color that one is more Tung Oil than Linseed Oil for example?
I'm talking about Minwax Tung Oil Finish, Formby's Tung Oil, etc. I've heard the trope that they contain none, but tung oil is not hazardous and does not need to be present on the SDS. You'll see from most of Waterlox' SDS sheets have no mention of Tung Oil either except on their low VOC formulations.
