Crosslinking Resin Fixative DMDHEU
CAS Number: 1854-26-8
DMDHEU (Dimethylol Dihydroxyethylene Urea) is a durable press and crosslinking resin that simultaneously imparts crease resistance and improves dye fastness on cotton and blended fabrics. When cured with a catalyst, it crosslinks cellulose chains to lock dye molecules, enhancing wash fastness and shape retention. The industry standard resin for easy-care cotton shirting and home textile finishing.
