Description

2-Propenoic Acid, 2-Methyl-, Polymer With Butyl 2-Propenoate And Ethyl 2-Propenoate, Ammonium Salt is a water-soluble acrylic copolymer dispersion, specifically an ammonium salt of a terpolymer of methyl acrylate, butyl acrylate, and ethyl acrylate. This product is valued for its excellent film-forming properties, adhesion, and stability in aqueous systems. It is primarily used by formulators in the coatings, adhesives, and construction industries seeking high-performance, environmentally friendly binder solutions.

Application

• Architectural Coatings: Acts as a primary binder in interior and exterior paints, providing durability, scrub resistance, and low-temperature film formation.
• Industrial Coatings: Used in water-based primers, topcoats, and maintenance paints for metal, wood, and plastic substrates.
• Adhesives & Sealants: Serves as a key component in pressure-sensitive adhesives (PSAs), laminating adhesives, and caulks, offering good tack and cohesion.
• Construction Chemicals: Incorporated into cement modifiers, tile adhesives, and waterproofing membranes to improve flexibility, adhesion, and water resistance.
• Textile & Nonwovens: Functions as a binder and stiffener for fabrics and nonwoven materials, enhancing durability and hand feel.
• Paper Coatings: Used to improve the surface properties, printability, and strength of paper and paperboard.

Quality Control

Our production of this acrylic polymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance. Key parameters including solids content, pH, viscosity, and particle size are rigorously monitored. Certificates of Analysis (COA) detailing these specifications are provided with every shipment to guarantee the material meets your formulation requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 5°C and 30°C. This product is hygroscopic (moisture-sensitive). Protect from freezing and prolonged exposure to extreme heat to maintain product stability and prevent coagulation or viscosity changes.
