Safety Data Sheet

Getting an SDS for Mecrilate

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 Mecrilate 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.

04 · Precautionary statements

Mecrilate precautionary statements

CLP Annex VI assigns 9 precautionary statements to Mecrilate. They are grouped the way a label groups them: what to do before handling, what to do when something has already happened, how to store it and how to dispose of it.

05 · Names in the regulation

Mecrilate name in 23 EU languages

CLP Annex VI Part 3 is published in every language edition of the regulation, and the identification column is written out in each of them. Nothing below is translated by us: each line is the name as that edition prints it. Under Art. 18(2) the substance name from Annex VI is a lawful product identifier, so this is the wording to put on a label going to that market — and where the cell lists several designations, any one of them qualifies.

Mecrilate occupational exposure limits

US occupational exposure limits reported for Mecrilate. PEL is enforceable (OSHA), REL is a recommendation (NIOSH), IDLH is the concentration at which escape becomes impossible without injury.
Limit Value Source
PEL none See Appendix G The National Institute for Occupational Safety and Health (NIOSH)
REL 2 ppm (8 mg/m³) Occupational Safety and Health Administration (OSHA)
REL 4 ppm (16 mg/m³) Occupational Safety and Health Administration (OSHA)

These are United States values. The European Union sets its own indicative and binding limits, and the figure that applies at a given workplace is the one in the local regulation — not the one shown here.

Mecrilate storage conditions

The effectiveness of phenolic inhibitors is dependent on the presence of oxygen and the monomers must be stored under air rather than an inert atmosphere. Temp must be kept low to minimize formation of peroxides and other products. ... The acrylic esters may be stored in mild or stainless steel, or aluminum. /Acrylic acid & derivatives/

Is Mecrilate a carcinogen?

CLP Annex VI records no harmonised carcinogenicity classification for Mecrilate. Annex VI is a list of agreed classifications, not a list of substances found safe, so this is an absence of a classification rather than a clean bill of health.
