Safety Data Sheet

Getting an SDS for 2,2'-methylenebis-(3,4,6-t…

A Safety Data Sheet is written for a product, not for a substance: the supplier of the grade you actually buy issues it, so two suppliers of 2,2'-methylenebis-(3,4… issue two different sheets. That is why there is no single authoritative SDS for a substance to download — what there is, is the job of collecting the sheets for the products you hold and keeping them current as suppliers revise them.
