Cationic monomers contribute to outstanding adhesion to glass and metals, excellent water resistance after curing, and compatibility with various curing mechanisms. They are used in electronic assemblies, glass bonding, and specialty packaging.
Types include quaternary ammonium compounds, vinyl ethers, and epoxy-functional materials combining cationic polymerization benefits with epoxy performance properties. Recent developments focus on cationic photoinitiator systems with reduced sensitivity to cure inhibition by moisture or basic compounds and utilization in UV-curable systems for fast processing speeds.
