| Hazard Information | Back Directory | [General Description]
A clear colorless liquid with a pleasant odor. Less dense than water and insoluble in water. Vapors heavier than air. Flash point 180°F. Used in making of paints and plastics. | [Reactivity Profile]
2-ETHYLHEXYL ACRYLATE(103-11-7) polymerizes readily in the presence of heat and light generating much heat; reacts with strong oxidants. REF [Handling Chemicals Safely, 1980. p. 235]. | [Air & Water Reactions]
Insoluble in water. | [Hazard]
Questionable carcinogen. | [Health Hazard]
Inhalation of concentrated vapor causes drowsiness and convulsions. Liquid causes irritation of eyes and may irritate skin on prolonged exposure. Ingestion produces same symptoms as inhalation. | [Potential Exposure]
A potential danger to those involved
in the use of this monomer as a feedstock for chemical syntheses; in the manufacture of plastics; protective coatings,
including water-based paints; in paper treatment; the production of emulsion polymers. | [Fire Hazard]
Behavior in Fire: Heat can result in a severe polymerization with rapid release of energy. Sealed containers may rupture explosively if hot. | [First aid]
Skin Contact: Flood all areas of body that
have contacted the substance with water. Don’t wait to
remove contaminated clothing; do it under the water
stream. Use soap to help assure removal. Isolate contaminated clothing when removed to prevent contact by others.
Eye Contact: Remove any contact lenses at once. Flush
eyes well with copious quantities of water or normal saline
for a least 2030 minutes. Seek medical attention.
Inhalation: If convulsions are not present, give a glass or
two of water or milk to dilute the substance. Assure that
the person’s airway is unobstructed and contact a hospital
or poison center immediately for advice on whether or not
to induce vomiting. Ingestion: If convulsions are not present, give a glass or two of water or milk to dilute the substance. Assure that the person’s airway is unobstructed and
contact a hospital or poison center immediately for advice
on whether or not to induce vomiting | [Incompatibilities]
Unless inhibited, sunlight, heat, contaminants, or peroxides can cause dangerous polymerization.
Vapors are uninhibited and may polymerize, blocking
vents. Violent reaction with strong oxidizers, with risk of
fire and explosions. May form explosive mixture with air.
Incompatible with strong acids; aliphatic amines;
alkanolamines. | [Description]

| [Waste Disposal]
Spray into incinerator with
added flammable solvent. | [Characteristics]
2-Ethylhexyl acrylate (2-EHA) is one of the main base monomers used to make copolymers for adhesives and sealants, paints and coatings, printing inks, super absorbent polymers, building materials, acrylic rubbers and emulsions among other applications. 2-EHA is a unique building block for copolymers that provide low temperature flexibility, performance, hydrophobicity, water resistance, good weatherability and UV (sunlight) resistance. 2-EHA monomer has a Tg of – 65°C and has various industrial applications. | [Definition]
ChEBI: 2-Ethylhexyl acrylate is an ester of enoic acid. It is commonly used as a plasticizing co-monomer in the production of resins, which are utilized in various applications such as adhesives, latex, paints, textile and leather finishes, and coatings for paper. | [Preparation]
2-Ethylhexyl acrylate is obtained by esterifying acrylic acid and 2-ethylhexanol with sulfuric acid as a catalyst, and subsequently neutralizing, dealcoholizing and rectifying the mixture. | [Flammability and Explosibility]
