Description

2-Propenoic Acid, 2-Methyl-, Polymer With Ethenylbenzene, Ethyl 2-Propenoate And 2-Propenenitrile, Ammonium Salt is a high-performance, water-soluble acrylic copolymer designed for demanding industrial applications. This specialized polymer offers excellent binding, thickening, and film-forming properties, making it a critical component in formulations requiring durability and stability. It is primarily utilized by manufacturers in the coatings, adhesives, construction chemicals, and textile processing industries seeking to enhance product performance and process efficiency.

Application

• Architectural and Industrial Coatings: Acts as a key binder and thickener in water-based paints, providing improved scrub resistance, adhesion, and stability.
• Adhesives and Sealants: Used as a film-forming agent and rheology modifier in pressure-sensitive adhesives (PSAs) and construction sealants.
• Construction Chemicals: Serves as a redispersible polymer powder or additive in cementitious formulations, tile adhesives, and self-leveling compounds to enhance flexibility and water resistance.
• Textile and Non-Woven Binders: Provides durable binding and hand feel improvement in fabric coatings, pigment printing, and non-woven fabric production.
• Paper Coatings: Enhances the strength, gloss, and printability of paper and paperboard coatings.
• Leather Finishing: Used in topcoat formulations to provide a flexible, protective film with good adhesion.

Quality Control

Our production of this acrylic copolymer adheres to strict quality management systems. Every batch undergoes comprehensive testing for critical parameters including solids content, viscosity, pH, particle size, and mechanical stability to ensure consistent performance and batch-to-batch uniformity. Certificates of Analysis (COA) documenting all test results 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 affect product properties. Protect from freezing.
