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.

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.

Notclassified
storage
: Color Code—Red: Flammability Hazard: Store ina flammable liquid storage area or approved cabinet awayfrom ignition sources and corrosive and reactive materials.Prior to working with this chemical you should be trainedon its proper handling and storage. Store in tightly closedcontainers in a cool, well-ventilated area or refrigeratoraway from oxidizers and light. Where possible, automatically pumpliquid from drums or other storage containers toprocess containers.
Shipping
Note: Unless inhibited, this material is a polymerization hazard. May be classified as a Combustible liquid, n.o.s. This class of compounds requires no particularshipping label. It falls in Hazard Class 3 and Packing GroupIII. Each reference to a Class 3 material is modified to read“COMBUSTIBLE LIQUID” when that material is reclassified in accordance with y173.150 (e) or (f) of this subchap_x0002_ter, or has a flash point above 60.5℃/141° F but below93℃/200°F.
Toxics Screening Level
The initial threshold screening level (ITSL) for 2-ethylhexyl acrylate is 18 μg/m3 based on an annual averaging time.
