Description

Poly(Ethyl Acrylate/Acrylic Acid) is a synthetic copolymer derived from ethyl acrylate and acrylic acid monomers, offering a unique balance of properties from its constituent polymers. This material is valued for its film-forming capability, adhesion promotion, and responsiveness to pH changes, making it a versatile functional additive and binder. It is primarily needed by manufacturers in the coatings, adhesives, textiles, and personal care industries seeking to modify rheology, enhance durability, or create stimuli-responsive formulations.

Application

• Coatings & Paints: Acts as a film-forming agent and rheology modifier in water-based architectural and industrial coatings, improving application properties and final film integrity.
• Adhesives & Sealants: Serves as a key polymeric binder in pressure-sensitive adhesives (PSAs) and construction sealants, providing tack, cohesion, and adhesion to various substrates.
• Textile Finishing: Used as a durable hand modifier and finishing agent for fabrics, imparting softness, wrinkle resistance, and improved drape.
• Personal Care Products: Functions as a film former and stabilizer in hair styling gels, mousses, and skin care products, offering hold and a non-tacky feel.
• Paper Coatings: Enhances the strength, printability, and gloss of paper and paperboard as a component of coating formulations.
• Thickening & Dispersing Agent: Utilizes its carboxylic acid groups to act as a thickener and dispersant in aqueous systems, including in detergents and agrochemical suspensions.

Quality Control

Our Poly(Ethyl Acrylate/Acrylic Acid) is manufactured under a strict quality management system. Each batch undergoes rigorous testing for critical parameters including monomer content, molecular weight distribution, solids content, viscosity, and pH to ensure consistent performance and batch-to-batch reproducibility. Certificates of Analysis (COA) documenting these specifications are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product properties.
