Description

2-Propenoic acid, butyl ester, polymer with ethyl 2-propenoate and N-(hydroxymethyl)-2-propenamide is a high-performance, crosslinkable acrylic copolymer designed for demanding industrial applications. This versatile polymer provides an excellent balance of film-forming properties, adhesion, and chemical resistance, making it a critical component in advanced coating and adhesive formulations. It is primarily utilized by manufacturers in the paints and coatings, textiles, and pressure-sensitive adhesive industries seeking to enhance product durability and performance. The compound is also known by several other names including butyl acrylate, ethyl acrylate, N-methylolacrylamide polymer.

Application

• Textile Finishing & Coatings: As a key binder and crosslinker for wash-resistant, durable-press (DP) finishes, providing wrinkle resistance and dimensional stability to fabrics.
• Industrial Paints & Protective Coatings: Used in water-based or solvent-based coating systems to improve film hardness, chemical resistance, and adhesion to various substrates like metal, plastic, and wood.
• Pressure-Sensitive Adhesives (PSAs): Serves as a functional copolymer to enhance tack, peel strength, and heat resistance in label, tape, and graphic film adhesives.
• Paper Coatings: Improves surface strength, printability, and water resistance of paper and paperboard products.
• Leather Finishing: Applied in topcoat formulations to provide a flexible, durable, and glossy finish with good handle.
• Fiberglass Sizing: Acts as a coupling agent and film-former to protect glass fibers and improve their compatibility with polymer matrices in composite materials.
• Non-Woven Binders: Provides cohesion and strength to non-woven fabrics used in hygiene products, filters, and wipes through thermal or chemical curing.

Quality Control

Our acrylic copolymer is manufactured under a stringent quality management system to ensure batch-to-batch consistency and performance reliability. Each lot undergoes comprehensive analysis, including tests for solids content, viscosity, pH, and residual monomer levels. Certificates of Analysis (COA) documenting these specifications are provided with every shipment. We support compliance with relevant global regulatory frameworks, including REACH.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (typically 15-25°C). Avoid exposure to extreme heat or freezing conditions to maintain product stability and prevent premature reaction or viscosity changes. Keep away from strong oxidizing agents.
