Polyoxymethylene Urea

Polyoxymethylene Urea (CAS 68611-64-3), also known as urea-formaldehyde resin, is a condensation polymer produced by reacting urea with formaldehyde.

Where is Polyoxymethylene Urea used?

• Textile finishing: imparts wrinkle resistance and dimensional stability to cotton and blended fabrics, forming the basis of durable press treatments
• Wood-based panel manufacturing: primary binder adhesive for particleboard, MDF, and plywood
• Paper and pulp: wet-strength agent improving resistance to moisture-induced tearing in packaging and specialty papers
• Coatings and surface treatments: cross-links with alkyd or acrylic systems to improve hardness, chemical resistance, and film integrity
• It functions as a cross-linking and curing agent.

Good to know: Cure speed and bond strength directly affect production throughput in panel and textile applications.

Commercial specifications

• Formulations differentiated by molar ratio, solids content, and free formaldehyde levels
• Technical and industrial grades; panel or textile industry standard grades available upon request
