Sinomer® 4-META

4-甲基丙烯酰氧乙基偏苯三酸酐 (4-META), CAS 70293-55-9, dental adhesive monomer, PSPI 粘接促进剂

Sinomer® 4-META is a unique 双官能 monomer that serves as a powerful 粘接促进剂. Its structure combines a polymerizable methacrylate group with a reactive anhydride group, enabling strong chemical bonding to substrates like metals and tooth structure while copolymerizing with resin systems. This amphiphilic nature promotes resin infiltration, making it essential for enhancing bond strength in dental adhesives, cements, and industrial applications such as photosensitive polyimides (PSPI) and specialty coatings.
