Description

Biodent CAS NO 12650-29-2 is a high-purity chemical compound, also known as 2,2-Bis(4-methacryloxyphenyl)propane, primarily utilized as a key monomer in advanced dental and medical polymer formulations. Its significance lies in its ability to form durable, biocompatible, and high-strength polymer networks, which are essential for long-lasting medical applications. This product is critically needed by manufacturers in the dental materials, orthopedic cement, and specialty medical device industries seeking reliable, high-performance raw materials.

Application

• Dental Composite Resins: A fundamental cross-linking agent for restorative materials, fillings, and crowns.
• Bone Cements: Used in orthopedic applications to create strong, adhesive cements for prosthetic fixation.
• Denture Base Materials: Imparts strength and durability to acrylic resins used in dentures.
• Medical Adhesives & Sealants: Serves as a core monomer in formulations requiring biocompatibility and strong bonding.
• Specialty Coatings: For medical devices and implants where a hard, wear-resistant, and biocompatible surface is required.
• 3D Printing Resins (Biomedical): A critical component in photopolymer resins for printing surgical guides, models, and custom implants.
