What is it?
BIS-MA is a methacrylic monomer based on bisphenol A which is used in dental composites and adhesives.

How do I avoid it?
You should avoid any contact with this substance. Avoidance requires reading labels, package inserts, Safety Data Sheets (SDS), and, on occasion, direct communication with the manufacturer.

It is optimal to completely avoid exposure to the ingredients to which you are allergic. If you must be exposed to this acrylate (for example, because of your job), you may try to wear nitrile gloves and change them every 10 minutes. Acrylates pass through nitrile gloves if they are worn for longer periods of time. Other gloves such as rubber latex gloves are less desirable since acrylates pass through them quickly.
