Description

1,3-Bis(Methoxymethyl)Urea is a versatile chemical building block and cross-linking agent characterized by its reactive methoxymethyl groups. This compound is valued for its ability to introduce durable, formaldehyde-free cross-links in polymer systems, enhancing material performance. It is primarily sought after by manufacturers in the resin, textile, leather finishing, and specialty polymer industries for applications requiring improved water resistance, dimensional stability, and mechanical properties.

Application

• Formaldehyde-Free Cross-Linking Agent for textile and leather finishing resins.
• Reactive Intermediate in the synthesis of thermosetting resins, including urea-formaldehyde and melamine-formaldehyde modifiers.
• Durable Press Finishes for cellulose-based fabrics to impart wrinkle resistance.
• Paper Wet-Strength Resins to improve the tensile strength of paper products when wet.
• Wood Adhesive Component for producing low-emission composite wood panels.
• Coating Formulations to enhance the hardness and chemical resistance of surface coatings.
• Pharmaceutical Intermediate in the synthesis of certain active pharmaceutical ingredients (APIs).
