Description

2-Propenoic Acid, Polymer With Ethyl 2-Propenoate And n-(Hydroxymethyl)-2-Methyl-2-Propenamide is a high-performance, cross-linkable acrylic copolymer designed for demanding industrial applications. This versatile polymer is valued for its ability to form durable, chemically resistant films and coatings upon curing. It is an essential raw material for manufacturers in the adhesives, coatings, textile, and paper industries seeking to enhance product performance and durability.

Application

• Industrial Adhesives & Sealants: Used as a key binder in pressure-sensitive adhesives (PSA), laminating adhesives, and construction sealants, providing excellent tack, cohesion, and water resistance.
• Protective & Decorative Coatings: Serves as a film-forming agent in water-based paints, industrial maintenance coatings, and wood finishes, offering good gloss, hardness, and weatherability.
• Textile & Nonwoven Binders: Applied as a durable binder for fabric coatings, pigment printing, and nonwoven fabrics, imparting wash fastness, soft hand feel, and dimensional stability.
• Paper & Packaging Coatings: Enhances the surface strength, printability, and oil/water resistance of paperboard, release papers, and packaging materials.
• Leather Finishing: Used in topcoat formulations for leather goods to provide a flexible, abrasion-resistant, and attractive finish.
• Cross-linking Component: The reactive N-methylolacrylamide (NMA) moiety allows for thermal or acid-catalyzed cross-linking, enabling the formulation of high-performance, thermoset coatings and composites.
