Ethyl Acrylate (CAS 140-88-5) is the ethyl ester of acrylic acid, a reactive monomer supplied as a clear, colorless liquid with a sharp, pungent odor, and it acts as a building block for polymers and resins, aqueous dispersions, acrylic elastomers and industrial coatings. It is typically supplied in Industrial Grade with a purity of 99.5% min and is inhibited with MEHQ to prevent premature polymerization.
This colorless, volatile liquid is characterized by its Highly Flammable nature and sharp, pungent odor. It serves as a critical building block for aqueous dispersions, acrylic elastomers, and specialty industrial coatings that require weather resistance.
The chemical’s ability to copolymerize with various monomers allows for the customization of resin hardness and flexibility. Its role as a Chemical Intermediate is vital for the development of modern paints, textile finishes, and high-performance adhesives.
