Description

Urea, Polymer With Formaldehyde And Phenol CAS NO 25104-55-6 is a thermosetting amino resin formed by the polycondensation of urea, formaldehyde, and phenol. This versatile polymer is valued for its excellent adhesive properties, high mechanical strength, and good chemical resistance, making it a critical component in durable composite materials. It is primarily needed by manufacturers in the woodworking, foundry, and abrasives industries for producing high-performance bonded products.

Application

• Wood Adhesive Binder: A key resin for manufacturing plywood, particleboard, and medium-density fiberboard (MDF), providing strong, water-resistant bonds.
• Foundry Sand Binder: Used as a core binder in metal casting processes to create precise sand molds with good collapsibility and thermal stability.
• Abrasive Wheel Production: Serves as a bonding agent in the manufacture of grinding wheels and abrasive cut-off discs, offering high strength and heat resistance.
• Friction Material Component: Incorporated into brake pads and clutch facings to enhance thermal stability and reduce noise.
• Surface Coating Resin: Utilized in industrial coatings and finishes to improve hardness, durability, and chemical resistance.
• Electrical Laminates: Acts as an impregnating resin for paper or fabric used in electrical insulating laminates and circuit boards.
• Molding Compounds: A base resin for compression or injection molding compounds requiring good dimensional stability and electrical properties.

Quality Control

Our Urea, Polymer With Formaldehyde And Phenol is manufactured under a strict quality management system. Each batch undergoes rigorous testing for key parameters such as viscosity, solid content, gel time, and free formaldehyde to ensure consistency and performance for industrial applications. Certificates of Analysis (COA) are available upon request to support your quality assurance protocols.

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); ensure containers are sealed after each use to prevent moisture absorption, which can affect product performance.
