2-Hydroxyethyl acrylate (CAS 818-61-1), a hydroxyl-functional acrylic monomer. It is used as a comonomer in thermosetting acrylic resins, where its hydroxyl group provides crosslinking sites with isocyanates, melamine, and epoxies. End uses include automotive and architectural coatings, photocure resins, adhesives, and acrylate grouts.
Frequently Asked Questions
What is hydroxyethyl acrylate used for?
2-Hydroxyethyl acrylate (HEA, CAS 818-61-1) is a hydroxyl-functional acrylic monomer used as a comonomer in thermosetting acrylic resins, where its hydroxyl group provides crosslinking sites with isocyanates, melamine, and epoxies. End uses include automotive and architectural coatings, UV/photocure resins, adhesives, and acrylate grouts.
What is the chemical formula of hydroxyethyl acrylate?
Hydroxyethyl acrylate has the molecular formula C5H8O3 and CAS number 818-61-1. It is an ester of acrylic acid bearing a 2-hydroxyethyl group, which gives it both polymerizable acrylate functionality and a reactive hydroxyl group.
Why does HEA provide crosslinking sites in acrylic resins?
The pendant hydroxyl group on HEA reacts with isocyanates, melamine, and epoxy curatives, so copolymerizing HEA into an acrylic resin builds in hydroxyl functionality for two-component crosslinking. This is the basis for its use in automotive clearcoats and topcoats.
Is hydroxyethyl acrylate DOT-regulated for shipping?
Yes. Hydroxyethyl acrylate ships under UN 2927. The correct shipping name, packing group, and any required stabilizer/inhibitor handling are detailed on the SDS, which ships with every order; confirm requirements with your carrier.
How is hydroxyethyl acrylate supplied in bulk?
RawSource supplies HEA in drums, IBC totes, and bulk for coatings and resin manufacturers. It is inhibited to control premature polymerization; confirm inhibitor type and level on the CoA. Request a bulk quote for current pricing and lead time.
