Description

Isodecyl Acrylate (CAS 1330-61-6) is a high-purity monoacrylate ester with the molecular formula C₁₃H₂₄O₂, widely utilized in advanced polymer and adhesive formulations. This clear, colorless to pale yellow liquid is characterized by its low volatility, excellent adhesion properties, and resistance to hydrolysis, making it a preferred choice for UV-curable coatings, pressure-sensitive adhesives (PSAs), and specialty elastomers. Its IUPAC name, 8-methylnonyl prop-2-enoate, reflects its branched alkyl chain structure, which enhances flexibility and compatibility with hydrophobic substrates. Isodecyl acrylate is supplied with stringent quality control to ensure minimal inhibitors (e.g., MEHQ) for optimal reactivity in free-radical polymerization. Suitable for industrial and research applications, it is stored under inert conditions to maintain stability.

Application

Isodecyl acrylate is primarily used as a reactive diluent in UV/EB-curable coatings and inks, imparting low viscosity and improved flexibility to cured films. In adhesive formulations, it enhances tack and peel strength in PSAs for automotive and medical tape applications. The monomer’s branched structure also makes it valuable in synthesizing impact-resistant acrylic copolymers for plastic modifiers.
