Description

2-Propenoic Acid Polymer With Butyl 2-Propenoate, Ethenylbenzene, (1-Methylethenyl)Benzene And Methyl 2-Methyl-2-Propenoate, Ammonium Salt is a specialized ammonium salt of a multi-component acrylic copolymer designed for high-performance applications. This product is engineered to deliver consistent rheological modification, binding, and film-forming properties in demanding industrial formulations. It is a critical raw material for manufacturers in the coatings, adhesives, and construction chemical sectors seeking reliable performance and supply chain stability.

Application

• Waterborne Industrial Coatings: Acts as a key binder and rheology modifier, providing excellent film formation, adhesion, and durability.
• Pressure-Sensitive Adhesives (PSAs): Used to formulate adhesives with balanced tack, peel strength, and shear resistance.
• Construction Chemicals: Enhances the performance of tile adhesives, grouts, and cementitious renders by improving workability, water retention, and bond strength.
• Textile and Non-Woven Binders: Provides fiber binding and coating with good hand feel and wash durability.
• Paper Coating and Sizing: Improves surface strength, printability, and water resistance of paper and paperboard.
• Leather Finishing: Used in topcoat formulations to provide a flexible, protective, and aesthetically pleasing finish.

Quality Control

Our production of this acrylic copolymer ammonium salt adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Quality is verified through parameters including solids content, pH, viscosity, particle size, and mechanical stability. A Certificate of Analysis (COA) documenting these specifications 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 temperatures between 15°C and 25°C (59°F - 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. Protect from freezing.
