Full Description

2-Ethylhexyl acrylate (CAS 103-11-7), a soft, low-Tg acrylic ester monomer. It is used to make pressure-sensitive adhesives, water-based paints and coatings, printing inks, and paper and textile treatments, and it copolymerizes with vinyl acetate and vinyl chloride.

Frequently Asked Questions

What is 2-ethylhexyl acrylate (2-EHA) used for?

2-Ethylhexyl acrylate (CAS 103-11-7) is a soft, low-Tg acrylic ester monomer. It is used to make pressure-sensitive adhesives, water-based paints and coatings, printing inks, and paper and textile treatments, and it copolymerizes with vinyl acetate and vinyl chloride.

Why is 2-EHA used in pressure-sensitive adhesives?

As a low-glass-transition (low-Tg) monomer, 2-EHA imparts softness and tack to the resulting copolymer, which is the key property profile for pressure-sensitive adhesives. It is also used as a soft comonomer in water-based paint binders.

What is the chemical formula and CAS number of 2-EHA?

The molecular formula is C11H20O2 and the CAS number is 103-11-7. It is an acrylic acid ester, classified within the ester family and under HS 2916.12 (esters of acrylic acid).

Does 2-ethylhexyl acrylate require an inhibitor for storage?

As a reactive acrylate monomer, 2-EHA is typically supplied with a polymerization inhibitor (such as MEHQ) and handled to prevent premature polymerization. Consult the SDS and technical data sheet for the inhibitor level and storage conditions of the supplied grade.

What is the bulk price of 2-EHA and is an SDS available?

An SDS and CoA accompany bulk shipments. Pricing depends on volume and packaging; submit a bulk RFQ with your required quantity for a current quote.
