Description

Urea, Reaction Products With Formaldehyde CAS NO 68611-64-3 is a versatile class of amino resins formed by the controlled reaction of urea and formaldehyde. These products are essential for providing durable, cross-linked polymer networks in industrial applications. They are primarily required by manufacturers in the coatings, adhesives, textiles, and paper industries seeking to enhance product performance and durability.

Application

• Coatings & Paints: As a cross-linking agent in thermosetting industrial and automotive coatings to improve hardness, chemical resistance, and gloss.
• Adhesives & Binders: Key component in wood adhesives (e.g., for particleboard and MDF) and foundry sand binders, offering excellent bonding strength and water resistance.
• Textile Finishing: Used for durable press and wrinkle-resistant finishes on cotton and cellulose-based fabrics.
• Paper & Packaging: Employed as a wet-strength resin to improve the tear resistance and durability of paper products, especially in packaging.
• Molding Compounds: As a resin component in electrical components and decorative laminates for its good electrical properties and moldability.
• Leather Processing: Utilized in retanning and finishing processes to improve the fullness and dye affinity of leather.

Quality Control

Our Urea, Reaction Products With Formaldehyde is manufactured under strict process controls to ensure batch-to-batch consistency and performance. Quality is verified through parameters such as solids content, viscosity, free formaldehyde content, and gel time. A Certificate of Analysis (COA) documenting these specifications is provided with every shipment to guarantee compliance with your technical requirements.

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). Keep away from heat sources and incompatible materials. Prolonged storage at elevated temperatures may lead to increased viscosity or pre-gelation.
