Description

2-Propenoic Acid, Ethyl Ester, Polymer With Sodium 2-Propenoate is a synthetic copolymer of ethyl acrylate and sodium acrylate, known for its excellent film-forming and thickening properties. This versatile polymer is engineered to provide superior performance as a rheology modifier and binder in aqueous systems. It is a critical raw material for formulators in the adhesives, coatings, and personal care industries seeking to enhance product stability and texture.

Application

• Pressure-Sensitive Adhesives (PSAs): Acts as a primary film-forming agent and tackifier for labels and tapes.
• Water-Based Paints & Coatings: Serves as a binder and thickener to improve application properties and film integrity.
• Personal Care Products: Used as a stabilizer and viscosity modifier in creams, lotions, and hair styling gels.
• Textile & Nonwoven Binders: Provides durable binding and hand-feel modification for fabrics and fibers.
• Paper Coatings: Enhances strength, printability, and gloss in paper finishing applications.
• Construction Chemicals: Functions as a redispersible powder or additive in tile adhesives and cementitious mortars.

Quality Control

Our 2-Propenoic Acid, Ethyl Ester, Polymer With Sodium 2-Propenoate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent performance, including checks for solids content, viscosity, pH, and particle size. Certificates of Analysis (COA) documenting full specifications are available upon request to support your quality assurance protocols.

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/59-77°F). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed when not in use to prevent absorption of atmospheric moisture, which can alter product characteristics.
