Description
2-Ethylhexyl methacrylate (CAS 688-84-6) is a long-chain alkyl methacrylate monomer, also known commercially as Acryester EH and Blemmer EHMA 25, and referenced under synonyms including H 22 and NSC 32647. It carries no assigned E-code and is classified under HS code 29161290.
In polymer manufacturing, it copolymerises with harder monomers such as methyl methacrylate to introduce flexibility and lower the glass transition temperature of acrylic resins used in coatings and adhesives. In personal care formulations, its ester structure contributes emollient character, and it functions as a reactive crosslinker in UV-curable printing and packaging systems.
Supplied as an inhibited liquid grade meeting REACH registration requirements, it is available in standard drum and IBC packaging formats. Buyers should confirm inhibitor type and concentration for storage compatibility. No Ph.Eur. or FCC monograph applies to this substance.
