  • Applications

    2-(tert-Butylamino)ethyl methacrylate (CAS 3775-90-4) is primarily used as a protected amino-functional methacrylate monomer for copolymerization to introduce pendant amine groups in polymers. It serves as a key intermediate for synthesizing amino-containing polymers and materials for coatings and adhesives, where deprotection yields cationic functionalities that enhance adhesion and crosslinking performance. It also functions as a monomer for UV-curable coatings and inks, enabling improved pigment binding and network formation through reactive amine sites. Additionally, the compound is used as a protected monomer for surface-modification resins intended for electronics and optoelectronic substrates, allowing post-synthesis modification of polymer surfaces. In industrial formulations and polymer research, it is commonly evaluated for use in thermally or UV-curable systems, with suitability subject to local regulations and formulation limits.
