Sinomer® Bis-GDMAP is a high-purity, multifunctional phosphate methacrylate monomer engineered for advanced dental restorative materials. As a critical reactive component, it performs several essential functions: it copolymerizes with other resin monomers (e.g., Bis-GMA, UDMA, HEMA) to form a robust polymer matrix, provides strong and durable adhesion to tooth structure through its reactive phosphate group, and allows for the fine-tuning of the composite’s refractive index and aesthetics to ensure seamless integration with natural dentition. This unique combination of properties makes it indispensable for formulating high-performance, biocompatible dental composites, adhesives, and cements.
