Description

Isobornylmethacrylate CAS NO 16868-12-5 is a high-purity, monofunctional methacrylate monomer characterized by its bulky, rigid isobornyl group. This structure is critical for imparting exceptional properties such as high glass transition temperature (Tg), excellent hydrophobicity, and superior chemical resistance to polymer formulations. It is an essential raw material for manufacturers seeking to enhance the performance and durability of advanced polymeric materials. Key industries that rely on this specialty monomer include UV-curable resins, high-performance coatings, advanced adhesives, and optical polymers.

Application

• UV-Curable Coatings & Inks: A key component in formulations requiring fast curing, high cross-link density, and outstanding surface hardness for wood, plastic, and metal substrates.
• Adhesives & Sealants: Used to improve adhesion, flexibility, and environmental resistance in structural, pressure-sensitive, and anaerobic adhesives.
• Optical Polymers & Lens Materials: Imparts high refractive index, low color, and excellent clarity for optical fibers, lenses, and LED encapsulants.
• Engineering Plastics & Modifiers: Serves as a copolymer to enhance heat resistance, dimensional stability, and mechanical strength of acrylics and other polymers.
• Dental & Medical Composites: Employed in biocompatible resin systems for dental restoratives and medical devices due to its low shrinkage and good mechanical properties.
• Specialty Elastomers: Modifies the Tg and improves the oil and solvent resistance of acrylic and other synthetic rubbers.

Quality Control

Our Isobornylmethacrylate is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including Gas Chromatography (GC) and Infrared Spectroscopy (IR), to ensure it meets precise specifications for purity, color, and inhibitor content. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing all critical parameters to support your quality assurance protocols and regulatory compliance needs.

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). This product is easily oxidized and should be stored under an inert atmosphere (e.g., nitrogen) when in partially used containers to prevent premature polymerization and maintain optimal quality. Keep away from heat, sparks, and open flame.
