Description
Diethylene glycol ethyl ether acrylate (CAS 7328-17-8) is a reactive acrylic monomer commercially known under trade names including SR 256, RC 20, Reactomer RC 20, and Carbitol Acrylate. It carries no assigned E-code and is classified under HS code 29161290.
In UV-curable coatings and radiation-cured adhesives, this monomer functions as a reactive diluent, reducing viscosity while incorporating directly into the polymer network upon cure rather than evaporating as a solvent would. Its ether-glycol backbone also contributes plasticizing character, improving flexibility in cured films used in printing and packaging applications.
The material is supplied as a clear liquid and is subject to REACH registration requirements for European market use. Procurement teams should confirm supplier SDS documentation and purity grade specifications prior to ordering, as performance in formulation is sensitive to inhibitor levels and moisture content.
