Description

Diacrylamide is a high-purity, reactive bifunctional monomer featuring two acrylamide groups, making it a versatile cross-linking agent for advanced polymer synthesis. Its primary value lies in its ability to introduce stable covalent bonds into polymer networks, significantly enhancing mechanical strength, thermal stability, and chemical resistance. This compound is essential for R&D and production in industries such as specialty polymers, advanced coatings, and high-performance adhesives.

Application

• Cross-linking Agent for Acrylic Polymers: Used to create three-dimensional networks in superabsorbent polymers, hydrogels, and pressure-sensitive adhesives.
• Thermoset Resin Production: A key monomer for manufacturing high-performance, heat-resistant coatings and composite matrices.
• Photopolymer Formulations: Serves as a reactive diluent and cross-linker in UV-curable inks, coatings, and 3D printing resins.
• Bioconjugation and Immobilization: Utilized in biochemistry for covalently linking biomolecules to surfaces or other polymers.
• Ion-Exchange Resins: Incorporated into polymer backbones to enhance the stability and capacity of resins used in water treatment and purification.
• Analytical Chemistry Reagent: Employed in gel electrophoresis for the preparation of polyacrylamide gels with tailored pore sizes.
