Description

Cinnamyl Methacrylate is a specialty acrylate monomer featuring a cinnamyl group, which imparts unique properties to polymer chains. This compound is valued for its ability to introduce UV-absorbing characteristics, enhanced refractive index, and improved adhesion in advanced polymeric materials. It is primarily sought by R&D and production teams in the photoresist, optical lens, adhesive, and high-performance coating industries for formulating products with specific functional attributes.

Application

• Photoresists & Photopolymers: A key monomer for formulating UV-curable resins used in semiconductor fabrication and 3D printing, leveraging its photoreactive cinnamyl moiety.
• Optical Materials: Used in the synthesis of polymers for optical lenses, waveguides, and films where a high refractive index and UV stability are critical.
• Adhesives & Sealants: Incorporated to enhance the adhesion, cross-linking density, and environmental resistance of acrylic-based pressure-sensitive and structural adhesives.
• Specialty Coatings: Serves as a functional monomer in hard, protective coatings for electronics, automotive, and industrial finishes, improving scratch and chemical resistance.
• Dental & Biomedical Polymers: Employed in the development of biocompatible polymers for dental composites and other medical devices requiring specific mechanical and curing properties.
• Modifier for Synthetic Resins: Used to copolymerize with other acrylates or styrene to tailor the flexibility, glass transition temperature (Tg), and weatherability of the final resin.
