Description

Urea, Polymer With Formaldehyde, Isobutylated is a high-performance, modified amino resin widely used in industrial coatings and adhesives. This specialized polymer offers enhanced compatibility with non-polar systems and improved flexibility and water resistance compared to standard urea-formaldehyde resins. It is a critical raw material for formulators in the paints, coatings, printing inks, and adhesive industries seeking to develop high-quality, durable products.

Application

• Industrial & Automotive Coatings: Used as a crosslinking agent in baking enamels and coil coatings to provide excellent hardness, chemical resistance, and gloss.
• Wood Finishes: A key component in acid-curing lacquers and varnishes for furniture, cabinets, and flooring, offering fast cure and superior surface properties.
• Printing Inks: Employed in overprint varnishes and specialty inks to enhance rub resistance, gloss, and drying performance.
• Adhesives & Sealants: Functions as a curing agent and modifier in structural and assembly adhesives, improving bond strength and environmental durability.
• Metal Primers: Contributes to the corrosion resistance and adhesion promotion in primer formulations for metal substrates.
• Can & Container Coatings: Used in interior and exterior coatings for food and beverage containers due to its good resistance properties.
