Description

Urea, Polymer With Ammonium Chloride ((Nh4)Cl), Cyanoguanidine And Formaldehyde CAS NO 9075-85-8 is a specialized amino resin co-polymer formed through the condensation reaction of urea, cyanoguanidine (dicyandiamide), and formaldehyde, subsequently modified with ammonium chloride. This compound matters for its ability to provide enhanced thermosetting properties, chemical resistance, and binding strength in demanding industrial applications. Key industries that need this high-performance polymer include the adhesives, coatings, and textile finishing sectors, where it serves as a critical cross-linking agent and modifier.

Application

• Adhesive Formulations: As a cross-linking resin in wood adhesives (e.g., particleboard, plywood) and laminating adhesives to improve water resistance and bond strength.
• Industrial Coatings: Used in thermosetting powder coatings and coil coatings to enhance durability, hardness, and chemical resistance.
• Textile Finishing: Acts as a durable press resin and cross-linker for cellulose-based fabrics, providing wrinkle resistance and dimensional stability.
• Paper Saturation: Employed in wet-strength resins for paper and packaging products to improve performance under humid conditions.
• Foundry Binders: Serves as a core binder in sand casting processes for metal foundries.
• Flame Retardant Systems: Utilized as a component in intumescent coatings and materials due to the nitrogen-rich structure from cyanoguanidine and urea.
• Composite Materials: Functions as a matrix resin or modifier in fiber-reinforced plastics and molding compounds.

Quality Control

Our production of Urea, Polymer With Ammonium Chloride, Cyanoguanidine And Formaldehyde adheres to stringent quality management protocols. Each batch undergoes rigorous testing to ensure consistency in key parameters such as viscosity, solids content, gel time, and free formaldehyde levels. Certificates of Analysis (COA) documenting these specifications are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed after opening to prevent moisture absorption, which can affect product performance. Keep away from heat sources and incompatible materials.
