Thiopropionic Acid

Thiopropionic Acid

MPA can be used to esterify Polyols resulting in Polythiols which are used as crosslinking additives in Coatings, Adhesives and Sealants and as monomers to manufacture Optical Resins. They react rapidly with isocyanates, unsaturated monomers (thiol-ene reaction) and epoxies.

Laboratory Chemical Safety Summary (LCSS)

The esters of MPA, like 2-Ethylhexyl 3-Mercaptopropionate, also called 2-EHMP, and Iso-Octyl 3-Mercaptopropionate, also called IOMP, react like regular mercaptans and show long term stability. Both are also key intermediates in the manufacture of tin heat-stabilizers for PVC.

MPA can be used to esterify Polyols resulting in Polythiols which are used as crosslinking additives in Coatings, Adhesives and Sealants and as monomers to manufacture Optical Resins. They react rapidly with isocyanates, unsaturated monomers (thiol-ene reaction) and epoxies.
