Description

1,3-Adamantanediol Dimethacrylate is a high-purity, multifunctional methacrylate monomer featuring the rigid adamantane core. This compound is valued for its ability to impart exceptional thermal stability, chemical resistance, and hardness to polymer networks. It is primarily sought after by formulators and researchers in the advanced photoresists, dental materials, optical lenses, and high-performance coatings industries.

Application

• Photoresist Formulations: A key monomer in advanced photoresists for semiconductor manufacturing (KrF, ArF lithography) due to its low shrinkage and high etch resistance.
• Dental Composites & Restoratives: Enhances the mechanical strength, wear resistance, and biocompatibility of dental filling materials and crown & bridge resins.
• Optical Materials: Used in the production of high-refractive-index, transparent polymers for optical lenses, waveguides, and LED encapsulants.
• Coatings & Inks: Imparts superior surface hardness, adhesion, and chemical durability to UV-curable coatings, inks, and adhesives.
• 3D Printing Resins: Serves as a performance additive in stereolithography (SLA) and digital light processing (DLP) resins to improve part toughness and thermal properties.
• Modifier for Specialty Polymers: Incorporated as a cross-linking agent or co-monomer to enhance the thermal and mechanical properties of engineering plastics.
