Description

Poly(Urea-Co-Formaldehyde), Methylated is a synthetic, thermosetting amino resin derived from the co-condensation of urea and formaldehyde, followed by methylation. This chemical modification enhances its solubility and stability in various organic systems, making it a valuable polymeric intermediate. It is primarily used in the formulation of high-performance industrial coatings, adhesives, and cross-linking agents where controlled reactivity and film-forming properties are required.

Application

• Industrial Coatings: As a cross-linking resin in automotive, coil, and can coatings to improve hardness, chemical resistance, and durability.
• Adhesives & Binders: A key component in wood adhesives (e.g., for particleboard and plywood) and foundry sand binders.
• Textile Finishing: Used as a durable press reagent and cross-linker for cellulose fibers to impart wrinkle resistance.
• Paper Sizing: Enhances wet strength and water resistance in specialty paper products.
• Surface Modification: Acts as a modifier for pigments and fillers to improve dispersion and compatibility in polymer matrices.
• Encapsulation Resins: For electrical components and controlled-release fertilizer systems.
