Description

2-Propenoic Acid, 2-Methyl-, Polymer With Butyl 2-Propenoate, Methyl 2-Propenoate And 2-Propenenitrile, Sodium Salt is a specialized acrylic copolymer designed for high-performance applications requiring excellent film-forming, binding, and stability properties. This water-soluble polymer is valued for its ability to modify rheology, enhance adhesion, and provide consistent performance in demanding formulations. It is a critical raw material for manufacturers in the coatings, adhesives, construction chemicals, and textile processing industries seeking reliable and effective polymeric additives.

Application

• Coatings & Paints: Acts as a key binder and film-forming agent in water-based architectural and industrial coatings, providing durability and wash resistance.
• Adhesives & Sealants: Used as a primary polymer in pressure-sensitive adhesives (PSAs) and construction sealants for strong, flexible bonds.
• Construction Chemicals: Serves as a crucial additive in cementitious formulations, tile adhesives, and grouts to improve workability, water retention, and adhesion.
• Textile & Nonwovens: Functions as a binder and finishing agent for fabrics and nonwoven materials, enhancing stiffness, hand feel, and color fastness.
• Paper Coating: Employed in paper and paperboard coatings to improve surface gloss, printability, and ink holdout.
• Leather Processing: Used in finishing formulations to provide a protective, flexible topcoat with good aesthetic properties.

Quality Control

Our production of this acrylic copolymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters including solid content, viscosity, pH, and ionic character are rigorously monitored. A comprehensive Certificate of Analysis (COA) detailing all specification results is provided with every shipment 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 affect product performance. Keep away from incompatible materials such as strong oxidizing agents.
