Isobornyl Acrylate: The Eco-Friendly Acrylate Fueling Innovation in Coatings and Polymers
As the demand for high-performance, sustainable materials grows, Isobornyl Acrylate (IBOA) is emerging as a key monomer in advanced coatings, adhesives, and polymer systems. Known for its excellent balance of rigidity, adhesion, and low volatility, IBOA is particularly prized in UV-curable formulations and high-gloss coatings.
What is Isobornyl Acrylate?
Isobornyl Acrylate is a monofunctional acrylate monomer derived from isoborneol and acrylic acid. It belongs to a class of bio-based acrylates with a rigid bicyclic structure, which imparts unique performance benefits. With a high glass transition temperature (Tg) and low viscosity, IBOA is often used to improve hardness and weather resistance in polymer films and coatings.
Chemical Formula: C13H20O2CAS Number: 5888-33-5
Key Properties
Low Shrinkage: Minimizes warping or dimensional changes during polymerization.
High Tg (~90°C): Enhances hardness and heat resistance in cured resins.
Low Odor & Volatility: Ideal for consumer-facing or indoor applications.
UV-Curability: Fast curing under UV light makes it valuable in digital printing and electronics.
Applications of Isobornyl Acrylate
UV-Curable Coatings: IBOA is a common reactive diluent in wood finishes, automotive clear coats, and floor coatings due to its low yellowing and excellent surface hardness.
Adhesives & Sealants: It improves bond strength and weatherability in structural adhesives and pressure-sensitive adhesives (PSAs).
3D Printing Resins: IBOA enhances print resolution and mechanical strength in photopolymer formulations for SLA and DLP printing.
Optical Applications: Its high refractive index and clarity make it suitable for lenses, displays, and optical fibers.
Electronics & PCB Coatings: Provides dielectric strength and chemical resistance in electronic encapsulants and conformal coatings.
