1,12-Dodecanediol dimethacrylate
1,12-Dodecanediol dimethacrylate, identified by CAS 72829-09-5, is a high-performance bifunctional monomer characterized by its long, linear aliphatic chain. This hydrophobic dimethacrylate serves as an effective cross-linking agent in various polymer systems, offering a unique balance of flexibility and chemical resistance. Its molecular structure, consisting of a twelve-carbon spacer between two reactive methacrylate groups, allows for the development of polymers with reduced shrinkage and enhanced toughness compared to shorter-chain counterparts.
In industrial and research settings, this material is valued for its low volatility and excellent compatibility with a wide range of organic resins. It is typically handled as a liquid monomer and requires stabilization with inhibitors to prevent premature polymerization. Its inherent hydrophobicity makes it particularly suitable for applications where moisture resistance and long-term durability are critical requirements. As a versatile building block, it enables the fine-tuning of mechanical properties in specialized coatings, adhesives, and composite materials.
• In the formulation of advanced adhesives and sealants, 1,12-Dodecanediol dimethacrylate acts as a reactive diluent and cross-linker. The long aliphatic chain provides significant internal plasticization, which improves the impact strength and flexibility of the cured adhesive. This makes it an ideal component for bonding substrates that undergo thermal expansion or mechanical stress, ensuring the integrity of the bond remains intact under demanding environmental conditions.
• Within the coatings industry, this monomer is utilized to enhance the water repellency and weatherability of protective films. Its hydrophobic nature reduces water uptake, while the bifunctional methacrylate groups ensure a dense, chemically resistant cross-linked network. It is frequently incorporated into UV-curable and electron-beam curable systems to achieve high-performance finishes that resist degradation from moisture, chemicals, and abrasion.
• In the development of dental materials and specialized composites, 1,12-Dodecanediol dimethacrylate is employed to minimize polymerization shrinkage. The relatively high molecular weight and long spacer group contribute to a lower volumetric contraction during the curing process compared to standard monomers. This property is essential for maintaining dimensional stability and improving the marginal fit of composite restorations or precision-molded industrial components.
