Pentaerythritol triacrylate (PETA)
What is it?
PentaerythritolPentaerythritol triacrylate is an acrylate monomer used in manufacturing coatings, inks, and adhesives. It can be used in materials to make them resistant to weather, water, and abrasion.
What is a monomer? A monomer is a starting material or single unit from which a polymer is built. It refers to the repeat units that make up the polymer chains. Example: Ethylene is the monomer for polyethylene, and styrene for polystyrene.
How can I avoid it?
Avoidance requires reading the product 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.
