2-Hydroxyethyl acrylate Usage And Synthesis

Description

2-Hydroxyethyl acrylate (HEA) forms homopolymers and copolymers. HEA is used mainly either as a co-monomer in the manufacture of polymers or as a chemical reactant in the manufacture of chemical intermediates. In the manufacture of polymers, HEA can be co-polymerized with acrylic acid, acrylates, methacrylates, vinyl acetate, vinyl chloride, vinylidene chloride, styrene, butadiene, and the like. Co-reactants with HEA include aromatic and aliphatic isocyanates, anhydrides, and epoxides. The polymers and chemical intermediates made with HEA find applications in automotive top coatings, architectural coatings, photocure resins, and adhesives. Globally about half of the HEA produced is used in the production of acrylic enamels for the automotive industry, where a clear topcoat is applied to a pigmented base coat to increase corrosion protection and durability.

Chemical Properties

Hydroxyethyl acrylate is a clear colorless liquid. miscible with water, soluble in general organic solvents. The commodity generally contains 400ppm of hydroquinone methylether, a polymerization inhibitor. Hydroxyethyl acrylate is a difunctional acrylate monomer with the characteristic high reactivity. Hydroxyethyl acrylate is used in a crylics for coatings, adhesives and UV reacitve oligomers. It can be used for crosslinking with isocyantes or melamines.

Uses

As a reactive monomer 2-Hydroxyethyl acrylate is used as a crosslinking agent for resins, plastics and rubber modifiers. Further, it is used in the synthesis of amphilic block copolymers by nitroxide mediated living radical polymerization. In addition to this, it is used to prepare tuned poly(hydroxyethyl acrylate) by atom transfer radical polymerization.

Uses

2-Hydroxyethyl acrylate is an acrylic monomer for use in UV inks, adhesives, lacquers, artificial nails, etc.

Definition

ChEBI: 2-Hydroxyethyl acrylate is a functional monomer for the manufacture of thermosetting acrylic resins.

General Description

A clear colorless liquid. Less dense than water. Vapors heavier than air. Corrosive to tissue. Flash point 120°F. May polymerize exothermically if heated or contaminated. If the polymerization takes place inside a container, the container may rupture violently. Used to make plastics.

Air & Water Reactions

Flammable. Slightly soluble in water.

Reactivity Profile

A functional monomer of thermosetting acrylic resins.

Health Hazard

Inhalation causes irritation of nose and throat. Contact with liquid irritates eyes and skin.

Fire Hazard

Behavior in Fire: Containers may explode

Flammability and Explosibility

Non flammable

Potential Exposure

2-Hydroxyethyl acrylate is contained in Lowicryl 4KM and K11M resins. It caused contact dermatitis in workers embedding media for electron microscopy. It may also be contained in ultraviolet-curable nail gel used for photobonded sculptured nails.
