4-META

Dental resin adhesive formulation: It is the most commonly used adhesion promoter in dental resins. The anhydride group in its structure can bond with dental metal substrates, while the methacrylate group can polymerize and copolymerize with composite resin monomers. This dual reactivity enables it to enhance the bonding strength between resin materials and dental tissues (such as dentin and enamel) as well as between resin and dental metal components. Moreover, it has both hydrophilic and hydrophobic groups, which can promote other dental resin monomers to diffuse into the tooth structure and form a resin-impregnated mixed layer, further improving the stability and durability of the bond.

Repair of dental fractures: It can be used to prepare special resins for bonding broken tooth fragments. Specifically, it can be applied to fix vertical root fractures of teeth by bonding the broken root fragments together, which provides an effective minimally invasive repair method for clinical dental fracture treatment and helps retain the integrity of the affected tooth to the greatest extent.

Improvement of bonding between dental metal and acrylic resin: In the production of dental restorations such as dentures and crowns, it can solve the problem of poor bonding between metal parts and acrylic resin. By adding 4-META to the material system, the firmness of the combination of the two materials is significantly improved, avoiding the problem of detachment of the resin part from the metal part during long-term use of the restoration.

Enhancement of interfacial adhesion of composites: In the production of thermosetting and thermoplastic composites, 4-META can enhance the interfacial adhesion between inorganic substrates (like glass fibers, mineral fillers, metal surfaces) and polymer matrices. This efficient adhesion ensures the effective transfer of stress between the matrix and the reinforcing materials, thereby improving the mechanical strength, rigidity and fracture resistance of the composites, and preventing problems such as delamination and premature failure of the materials.

Modification of existing resin systems: It can be easily integrated into free radical polymerization processes and mixed with conventional resin systems such as epoxy resin, acrylic resin and vinyl ester resin. This modification method can optimize the performance of the original resin without redeveloping a new production process, which is widely used in the development of lightweight structural components and high-strength composite materials.

Basic raw material for organic synthesis: As a dicarboxylic acid monomer derivative, it can be used as a raw material in organic synthesis experiments after hydrolysis. It is often used by researchers to develop new polymer materials or functional monomers, especially in the research of materials requiring adhesion and polymerization properties.

Research on material modification technology: In pharmaceutical and material science research, it is often used as a research object for adhesion promotion mechanisms. Its application characteristics in different material systems provide reference for the development of new adhesive materials and composite material modification technologies, such as the research on optimizing the bonding performance of medical polymer implants.
