Description

Urea, Polymer With Formaldehyde And Phenol, Methylated is a thermosetting amino resin, specifically a methylated urea-formaldehyde (UF) resin modified with phenol. This chemical modification enhances the resin's performance characteristics, offering superior durability, water resistance, and thermal stability compared to standard UF resins. It is a critical industrial polymer for manufacturers requiring high-performance, formaldehyde-based binding and coating systems.

Application

• Wood Adhesives: Primary binder for manufacturing plywood, particleboard, and medium-density fiberboard (MDF), where improved moisture resistance is required.
• Surface Coatings: Key component in industrial baking enamels and can coatings, providing excellent hardness, gloss, and chemical resistance.
• Foundry Sand Binders: Used as a core binder in metal casting processes for its fast curing and good collapsibility properties.
• Textile Finishing: Employed in durable press and wash-and-wear fabric treatments to impart crease resistance and dimensional stability.
• Paper Impregnation: Used to saturate paper for producing laminates, decorative overlays, and electrical insulation materials.
• Friction Materials: Serves as a binder in brake linings and clutch facings, contributing to thermal stability and wear resistance.

Quality Control

Our Urea, Polymer With Formaldehyde And Phenol, Methylated is manufactured under a strict quality management system. Each batch is tested against key parameters including viscosity, solids content, free formaldehyde, and gel time to ensure batch-to-batch consistency and performance reliability for your formulations. Certificates of Analysis (COA) are provided with every shipment and are available upon request.

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/59-77°F). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent absorption of atmospheric moisture, which can alter viscosity and performance. Keep away from heat sources and incompatible materials.
