Description

Isobornyl Acrylate CAS NO 5888-33-5 is a monofunctional acrylate monomer characterized by its bulky, rigid isobornyl group. This structure is critical for imparting excellent adhesion, low shrinkage, and enhanced chemical resistance to polymer formulations. It is an essential raw material for formulators in the coatings, adhesives, and photopolymer industries seeking to improve the performance and durability of their products.

Application

• UV-Curable Coatings & Inks: A key reactive diluent and crosslinker in formulations for wood, plastic, and metal coatings, providing fast cure speeds, high hardness, and good flexibility.
• Adhesives & Sealants: Used in pressure-sensitive adhesives (PSAs) and structural adhesives to enhance tack, peel strength, and environmental resistance.
• Photopolymer Resins: Serves as a fundamental component in resins for 3D printing (SLA/DLP), printing plates, and optical fibers, contributing to low volatility and precise curing.
• Thermoset Composites: Incorporated into fiber-reinforced plastics (FRP) and gel coats to improve surface finish, weatherability, and mechanical properties.
• Modifier for Acrylic Polymers: Acts as a co-monomer to modify the glass transition temperature (Tg), solubility, and toughness of acrylic copolymers.
• Dental & Medical Materials: Employed in the synthesis of biocompatible polymers for dental restoratives and other medical devices requiring specific physical properties.

Quality Control

Our Isobornyl Acrylate is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including assay, purity, and impurity profile analysis, to ensure it meets precise specifications for performance-critical applications. A Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15-25°C (59-77°F). Keep away from heat, sparks, open flames, and incompatible materials such as strong acids, bases, and oxidizing agents. For long-term storage, consider under an inert atmosphere to prevent premature polymerization.
