2-(Tert-butylamino)ethyl methacrylate

2-(tert-Butylamino)ethyl methacrylate (CAS 3775-90-4) is a functional amino methacrylate monomer, commercially available under trade names including Ageflex FM 4 and Mhoromer BM 615. It carries no assigned E-code. The tert-butylamine group and polymerizable methacrylate double bond make it a reactive building block for polymer synthesis.

In coatings and adhesive formulations, it participates in free-radical polymerization to introduce basic amine functionality into polymer backbones, improving adhesion to metal substrates and enabling pH-responsive behavior. In automotive and industrial coatings, it serves as a cross-linking co-monomer and surface-modifying agent, enhancing wetting on low-energy surfaces.

This monomer is supplied as a clear liquid and is subject to REACH registration requirements within the European Economic Area. Procurement teams should confirm inhibitor levels and stabilization conditions with the supplier, as these affect shelf life and handling protocols. Standard packaging formats include drums and intermediate bulk containers.
