A grade-specific Safety Data Sheet (SDS) — with the complete hazard classification, handling precautions, and transport information — is supplied with every shipment and available on request. Confirm all safety and regulatory details against the SDS for your specific grade.
Request SDS →2-Hydroxyethyl methacrylate (HEMA, CAS 868-77-9) is a reactive hydroxy-functional methacrylate monomer. It is used in UV-curable inks, coatings and adhesives, acrylic resins, dental materials, and as a comonomer in hydrogels and contact-lens polymers.
Frequently Asked Questions
What is HEMA (hydroxyethyl methacrylate) used for?
HEMA (2-hydroxyethyl methacrylate, CAS 868-77-9) is a reactive hydroxy-functional methacrylate monomer. It is used in UV-curable inks, coatings, and adhesives, in acrylic resins, in dental methacrylate resins, and as a comonomer in hydrogels and contact-lens polymers. The free hydroxyl group enables crosslinking and further functionalization.
What products contain hydroxyethyl methacrylate?
HEMA is a building-block monomer found in UV/EB-curable coating and ink systems, acrylic adhesives, hydrogel and contact-lens polymers, and dental resin formulations. RawSource supplies the monomer in bulk to manufacturers who polymerize or formulate it; we do not sell finished consumer goods.
Is 2-hydroxyethyl methacrylate the same as hydroxyethyl methacrylate?
Yes. "Hydroxyethyl methacrylate" and "HEMA" are the common names for 2-hydroxyethyl methacrylate, CAS 868-77-9, formula C6H10O3. The "2-" denotes the hydroxyl position on the ethyl ester group.
What is the cost of bulk HEMA?
HEMA pricing is volume- and grade-dependent and tied to methacrylate feedstock markets, so we do not list a fixed price. Send your target quantity and packaging (drums, totes, or IBCs) for a current bulk quote; CoA and SDS accompany each shipment.
What is the HS code for hydroxyethyl methacrylate?
HEMA classifies under HS 2916.14 (esters of methacrylic acid). As a reactive monomer it is typically stabilized with inhibitor; confirm grade, inhibitor level, and the destination tariff line when ordering.
