Description

Urea, N,N'-Bis(Hydroxymethyl)-, Polymer With Formaldehyde And (Hydroxymethyl)Urea CAS NO 62073-57-8 is a thermosetting amino resin, a key chemical intermediate derived from the controlled reaction of urea with formaldehyde. This polymer is valued for its excellent cross-linking properties, which impart durability, hardness, and water resistance to final products. It is primarily sought after by manufacturers in the coatings, adhesives, and textile finishing industries for producing high-performance surface treatments and binders.

Application

• Coatings & Paints: As a cross-linking agent in industrial and automotive coatings to enhance film hardness, chemical resistance, and gloss.
• Adhesives & Binders: A core resin component in wood adhesives (e.g., particleboard, MDF) and foundry sand binders, providing strong, water-resistant bonds.
• Textile Finishing: Used in durable press (DP) and wash-and-wear finishes for cotton and cellulose blends to impart wrinkle resistance and dimensional stability.
• Paper & Packaging: As a wet-strength resin to improve the tear resistance and durability of paper products, especially under moist conditions.
• Leather Processing: Employed in retanning and finishing to improve the fullness, grain tightness, and water repellency of leather.
• Fiberglass Sizing: Acts as a coupling agent and binder in fiberglass reinforcements for composites, improving fiber-matrix adhesion.
