Description

4,8-Bis(Methacryloyloxymethyl)Tricyclo[5.2.1.02,6]Decane is a high-purity, cross-linking monomer featuring a rigid tricyclodecane core and two reactive methacrylate groups. This compound is valued for its ability to impart exceptional hardness, thermal stability, and low shrinkage to polymer networks, making it a critical performance additive. It is primarily sought by manufacturers in the advanced photoresist, optical lens, dental composite, and high-performance coating industries for developing next-generation materials.

Application

• Photoresists & Semiconductor Materials: A key cross-linker for high-resolution, chemically amplified photoresists used in semiconductor lithography, providing excellent etch resistance and pattern fidelity.
• Optical Polymers & Lens Manufacturing: Used to formulate optical adhesives, coatings, and plastic lenses (e.g., for eyeglasses and cameras) due to its high refractive index, clarity, and dimensional stability.
• Dental Composites & Restoratives: Enhances the mechanical strength, wear resistance, and biocompatibility of dental filling materials and restorative resins.
• High-Performance Coatings: Serves as a reactive diluent and cross-linker in UV-curable coatings, inks, and adhesives, improving surface hardness, chemical resistance, and cure speed.
• 3D Printing Resins (SLA/DLP): A vital component in formulations for stereolithography (SLA) and digital light processing (DLP) 3D printing, contributing to part accuracy and material toughness.
• Fiber-Reinforced Composites: Improves the interfacial adhesion and overall thermal/mechanical properties of fiberglass or carbon fiber reinforced polymer composites.
