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.

Sinomer® Bis-GDMAP is specifically designed as a key monomer for next-generation dental materials:
Dental Composite Resins: Functions as a co-monomer and adhesion promoter, contributing to the mechanical strength, aesthetic match (via optical property adjustment), and durable bonding of fillings, crowns, and bridges.
Dental Adhesives & Cements: Serves as a primary adhesive monomer in self-etch and universal bonding systems, creating a stable hybrid layer between the tooth substrate and restoration.
Specialty Restorative Formulations: Used where enhanced bond strength to enamel, dentin, or ceramics is required.
Available in sealed, light-resistant containers. Standard packaging is 25 kg/drum. Custom packaging is available upon request.
