For chemists, formulators, and product development specialists, understanding the fundamental chemical properties of a compound is the first step towards unlocking its full application potential. Triisopropylsilyl Acrylate (TISA), identified by CAS number 157859-20-6, is a prime example of a specialty chemical whose unique properties dictate its valuable use in advanced materials, particularly in coatings and polymer science.

Key Chemical Properties of Triisopropylsilyl Acrylate

Triisopropylsilyl Acrylate is an ester of acrylic acid and triisopropylsilanol. Its structure, C12H24O2Si, with a molecular weight of approximately 228.41 g/mol, provides distinct characteristics:

  • Appearance: It is typically described as a colorless to almost colorless clear liquid, indicating high purity.
  • Reactivity: As an acrylate, it readily undergoes free-radical polymerization, making it an excellent monomer for creating vinyl polymers. The bulky triisopropylsilyl group influences the polymerization process and the properties of the resultant polymer.
  • Hydrolytic Sensitivity: Organosilicon esters like TISA can exhibit some sensitivity to moisture, potentially undergoing hydrolysis. Proper storage conditions (e.g., in a dry, cool place, often at 0-10°C) are recommended to maintain its integrity.
  • Thermal Properties: Information from various sources indicates a boiling point around 230.7°C at atmospheric pressure or approximately 102°C at 10 mmHg, with a flash point around 77.6°C. These properties are crucial for process safety and formulation design.
  • Solubility: While specific data may vary, compounds with silyl groups generally exhibit solubility in many organic solvents.

Applications Driven by Chemical Properties

The combination of acrylate reactivity and the bulky, hydrophobic triisopropylsilyl group makes TISA highly sought after:

  • Marine Anti-fouling Coatings: This is its most prominent application. The silyl group can influence surface properties and aid in the controlled release of biocides, preventing marine growth on ship hulls.
  • Polymer Modification: TISA can be copolymerized with other monomers to modify the thermal stability, hydrophobicity, and mechanical properties of the resulting polymers for use in specialty adhesives, sealants, or advanced composites.
  • Resin Manufacturing: It serves as a key monomer in the production of specialized resins designed for demanding applications.
