Sinomer® 10-MDP is a high-purity, phosphate-based functional monomer widely used as a key adhesion promoter in self-etch dental adhesive systems. Its molecular structure combines a polymerizable methacrylate group with a strongly acidic phosphoric acid ester group, enabling simultaneous etching of tooth substrate and copolymerization with resin matrices. This results in a stable and durable hybrid layer, providing outstanding bond strength to enamel, dentin, and even zirconia ceramics.
