Description

Urea, Polymer With 2,2-Bis(Hydroxymethyl)-1,3-Propanediol, Formaldehyde And Methanol CAS NO 125302-11-6 is a specialized, cross-linked amino resin polymer derived from urea, pentaerythritol, and formaldehyde, modified with methanol. This engineered polymer is valued for its excellent thermosetting properties, chemical resistance, and ability to form durable, high-performance coatings and adhesives. It is a critical raw material for manufacturers in the industrial coatings, wood composite, and specialty adhesive sectors seeking to enhance product durability and performance.

Application

• Industrial & Automotive Coatings: As a cross-linking agent in high-performance baking enamels and primers, providing excellent hardness, chemical resistance, and gloss retention.
• Wood Finishes & Panel Laminates: A key resin component in melamine-urea-formaldehyde (MUF) systems for decorative laminates, furniture finishes, and parquet sealants.
• Paper & Textile Saturation: Used in wet-strength resins for paper and as a stiffening or water-repellent agent for textiles.
• Foundry Sand Binders: Acts as a core binder in the foundry industry for creating precise metal casting molds.
• Electrical Laminates: Employed in the production of printed circuit board (PCB) substrates and other electrical insulating materials.
• Specialty Adhesives: Formulation of high-strength, water-resistant adhesives for plywood, particleboard, and other engineered wood products.
