Kinetic Analysis of Storage Modulus Using the NETZSCH DMA 303 Eplexor^®

The Application: UV-Cured Resin Systems

UV-cured resin systems rely on Curing (Crosslinking Reactions)Literally translated, the term “crosslinking“ means “cross networking”. In the chemical context, it is used for reactions in which molecules are linked together by introducing covalent bonds and forming three-dimensional networks.crosslinking reactions to form robust three-dimensional networks, which impart vital material properties such as hardness, elasticity, and chemical resistance. Optimal Curing (Crosslinking Reactions)Literally translated, the term “crosslinking“ means “cross networking”.
