Dimethylaminoethyl methacrylate

Dimethylaminoethyl methacrylate (CAS 2867-47-2), commercially known as DMAEMA, is a reactive amino-functional monomer used in the synthesis of specialty polymers and copolymers. Its tertiary amine group enables pH-responsive behavior and cationic character in finished polymer systems. This makes it a preferred building block for performance-driven formulations across coatings, adhesives, and textile treatment chemistries. In coatings and adhesives, DMAEMA is copolymerized to introduce adhesion-promoting and crosslinkable functionality.

It is frequently utilized in waterborne and UV-curable systems to enhance overall durability. The textile and leather industries use DMAEMA-based polymers as fixatives and softening agents, where cationic charge improves fiber affinity and treatment longevity. In paper manufacturing, it contributes to wet-strength resins and retention aid formulations that enhance process efficiency and end-product performance. Printing and packaging applications rely on these copolymers in inkjet coatings and binder systems.

These systems require controlled surface interaction and ink receptivity for high-quality results. DMAEMA is supplied as a clear liquid, typically stabilized with a polymerization inhibitor to ensure safe handling and storage during transit. It is available in technical grade, with purity levels commonly at 98% or higher as standard for industrial polymerization use. Bulk quantities are offered in drums and IBC containers to meet various logistical needs.

Inhibitor type and concentration are specified on request to meet downstream process requirements. This ensures the material remains stable and effective for specific manufacturing protocols and high-performance chemical applications.
