Tetraethylene glycol dimethacrylate
Tetraethylene glycol dimethacrylate, identified by CAS number 109-17-1, is a difunctional methacrylic monomer characterized by its relatively long, flexible ethylene oxide backbone. This clear, low-viscosity liquid serves as an effective crosslinking agent in various polymerization processes. Its chemical structure, featuring two reactive methacrylate groups separated by a tetraethylene glycol chain, allows it to bridge polymer chains, thereby enhancing the mechanical and thermal properties of the resulting materials.
In industrial and research settings, this monomer is valued for its ability to impart flexibility and impact resistance to cured systems while maintaining a high degree of crosslinking density. Its low volatility and high boiling point make it a stable component during formulation and processing. As a reactive diluent, it helps manage the viscosity of resin systems without significantly compromising the final performance characteristics of the polymer matrix.
• Used extensively as a crosslinking agent in the production of specialized polymers and copolymers. Its difunctional nature enables the formation of three-dimensional networks, which significantly improves the structural integrity, solvent resistance, and thermal stability of plastics and elastomers. It is particularly effective in systems where a balance between rigidity and flexibility is required.
• Functions as a high-performance reactive diluent in UV-curable and electron-beam-curable coatings, inks, and adhesives. By reducing the viscosity of the formulation, it facilitates easier application and better substrate wetting. During the curing process, it integrates into the polymer backbone, contributing to reduced shrinkage and enhanced adhesion to various surfaces.
• Serves as a key component in the synthesis of hydrogels and other hydrophilic polymer systems. The ethylene glycol units in its structure provide a degree of hydrophilicity, making it suitable for applications involving moisture-sensitive environments or where controlled swelling behavior is desired. This makes it a versatile building block for advanced material science research.
• Employed in the formulation of anaerobic adhesives and sealants due to its excellent polymerization characteristics in the absence of oxygen. It helps provide the necessary strength and durability for thread-locking and pipe-sealing applications, ensuring reliable performance in mechanical assemblies and industrial maintenance.
