Trimethylolmelamine

Trimethylolmelamine (CAS 1017-56-7), also known commercially as Lyofix DM and Glazamine M, is a trifunctional melamine-formaldehyde resin intermediate used as a crosslinker and curing agent.

Where is Trimethylolmelamine used?

• Textile finishing: crease resistance and dimensional stability for cellulosic fabrics
• Coatings and adhesives: crosslinking alkyd, acrylic and polyester resins for hardness and chemical resistance
• Paper and leather: wet-strength agent and surface binder
• Printing and packaging: binder resin component for rheology and substrate adhesion
• It reacts with hydroxyl, carboxyl and amide groups to build durable network structures.

Good to know: Buyers should confirm methylol group content and free formaldehyde levels when evaluating grades for low-emission or regulated-end-use applications.

Commercial specifications

• Solids content typically 70–80%
• Less commonly a dry powder
