Description

N,N''-(Methylene-p-Phenylene)-Bis-[N'-(2-Hydroxyethyl)]Urea is a specialized chemical compound widely utilized as a formaldehyde scavenger and crosslinking agent in polymer chemistry. Its primary commercial value lies in its ability to effectively bind and neutralize free formaldehyde, enhancing product safety and stability. This product is essential for manufacturers in the resin, adhesive, textile finishing, and coatings industries seeking to improve material performance and meet stringent regulatory standards for formaldehyde emissions.

Application

• Formaldehyde Scavenger in Urea-Formaldehyde (UF) and Phenol-Formaldehyde (PF) Resins: Effectively reduces free formaldehyde content in resins used for wood composites like particleboard and MDF, ensuring compliance with emission standards such as CARB Phase 2 and E1/E0.
• Crosslinking Agent for Textile Finishing: Imparts durable press and wrinkle-resistant properties to cellulose-based fabrics, enhancing fabric quality and longevity.
• Stabilizer and Modifier in Adhesives and Coatings: Improves the shelf-life, water resistance, and mechanical strength of adhesive formulations and industrial coatings.
• Intermediate for Specialty Polymer Synthesis: Serves as a building block in the production of polyurethanes, epoxy hardeners, and other thermosetting polymers requiring hydroxyl and urea functionalities.
• Additive in Leather Tanning and Paper Processing: Acts as a retanning agent and wet-strength additive, improving material properties and process efficiency.
