Description

Dimethylol Ethylene Urea CAS NO 136-84-5 is a reactive, water-soluble urea-formaldehyde derivative widely recognized for its cross-linking properties. This compound is essential for imparting durable press and wrinkle-resistant finishes to cellulosic textiles, enhancing fabric performance and longevity. It is a critical raw material for manufacturers in the textile finishing, paper coating, and adhesive industries seeking to improve product durability and quality.

Application

• Textile Finishing Agent: Primary use as a durable press (DP) and wrinkle-resistant resin for cotton, rayon, and their blends.
• Paper Coating & Sizing: Used to improve wet strength, dimensional stability, and printability of paper and paperboard.
• Adhesive & Binder Formulation: Serves as a cross-linking agent in wood adhesives, leather finishing, and non-woven binders.
• Fiber Modification: Applied for anti-shrink and crease-recovery finishes on natural and synthetic fibers.
• Coatings & Polymers: Utilized as a monomer or cross-linker in thermosetting resin systems for coatings.
