Butyl Acrylate (BA) [MC-RM-AC-005]

Product Description

Butyl Acrylate (BA) is an important organic chemical compound with the chemical formula C₁₂H₂₂O₂. It is commonly used as a monomer in polymerization reactions and has widespread applications in industries such as coatings, adhesives, plastics, and inks. It is synthesized from acrylic acid and butanol. Below is a detailed explanation of Butyl Acrylate (BA):

Basic Information:
  • Chemical Formula: C₁₂H₂₂O₂
  • Molecular Weight: 186.3 g/mol
  • Appearance: A colorless or pale yellow liquid with a characteristic fruity odor.
  • Boiling Point: Approximately 142°C.
  • Melting Point: Approximately -78°C.
  • Solubility: Butyl acrylate is insoluble in water but soluble in most organic solvents like alcohols, ethers, and benzene.
Chemical Properties:
  • Good Polymerization Ability: Butyl acrylate is an important acrylate monomer with strong polymerization properties. It can undergo free radical polymerization to form polymers such as polybutyl acrylate (PBA).
  • Reactivity of the Ester Group: The ester group (-COO-) in butyl acrylate has high reactivity and can participate in esterification, crosslinking, and polymerization reactions.
  • Weather and Chemical Resistance: Polymers made from butyl acrylate typically exhibit good weather resistance, chemical resistance, and flexibility, making them suitable for applications that require durability.
Safety and Precautions:
  • Flammability: Butyl acrylate is a flammable liquid. It should be stored and used away from fire sources and high-temperature environments.
  • Irritant: Butyl acrylate has some irritant properties, particularly at high concentrations, and may irritate the skin, eyes, and respiratory system. Protective equipment such as gloves and goggles should be worn during use.
  • Storage Conditions: It should be stored in a cool, dry, and well-ventilated place, away from oxidizing agents, and moisture, to prevent polymerization or decomposition.
Main Applications:
  1. Coatings Industry:
    • Butyl acrylate is commonly used as one of the main components in coatings, especially in water-based coatings and industrial coatings. It serves as a monomer to synthesize polymers that improve adhesion, weather resistance, and gloss of the coatings.
    • It is widely used in automotive coatings, architectural coatings, and anticorrosion coatings.
  2. Adhesives:
    • Due to its good adhesion and flexibility, butyl acrylate is often used as a raw material in adhesives, especially in the production of pressure-sensitive adhesives (PSA). It helps to improve the adhesive strength and weather resistance of the glue.
  3. Textiles:
    • Butyl acrylate is widely used in textile coatings and fiber treatments. Polymers formed from butyl acrylate improve the durability, flexibility, and water resistance of textiles.
  4. Plastics:
    • Butyl acrylate is also used in the plastics industry, particularly in the production of thermoplastic plastics as a plasticizer to enhance flexibility and impact resistance.
  5. Inks and Coatings:
    • Butyl acrylate is used in inks and printing coatings to improve the flow properties, adhesion, and durability of the ink, enhancing the quality and longevity of printed materials.
  6. Other Uses:
    • Cosmetics and Personal Care Products: Butyl acrylate is used in some cosmetics and skincare products as a plasticizer or film-forming agent to improve the smoothness and comfort of the product.
    • Sealers and Tapes: Due to its excellent adhesion, butyl acrylate is also used in the production of sealants and adhesive tapes for sealing and waterproofing applications.
