Description

2-Butenedioic Acid (2E)-, Polymer With 1,3-Butadiene, 2-Methyl-2-Prope Noic Acid And 2-Propenenitrile, Ammonium Salt is a high-performance, water-soluble copolymer designed for demanding industrial applications. This specialized ammonium salt polymer offers excellent film-forming, binding, and dispersing properties, making it a critical component in formulations requiring stability and controlled rheology. It is primarily utilized by manufacturers in the coatings, adhesives, construction chemicals, and textile processing industries seeking reliable performance additives.

Application

• Industrial Coatings & Paints: Acts as a binder and rheology modifier in water-based architectural and industrial coatings, enhancing film integrity and application properties.
• Adhesives & Sealants: Serves as a key polymeric component in pressure-sensitive adhesives (PSAs) and construction sealants, providing tack and cohesion.
• Construction Chemicals: Used as a dispersant and plasticizer in cementitious products, tile adhesives, and self-leveling compounds to improve workability and water retention.
• Textile & Leather Processing: Functions as a finishing agent, binder for pigments and dyes, or a component in polymer emulsions for fabric coating and non-woven binders.
• Paper Coating & Sizing: Employed to improve strength, printability, and surface properties of paper and paperboard.
• Specialty Dispersions: Utilized as a stabilizer and compatibilizer in the formulation of pigment dispersions and ceramic slurries.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product performance. Keep away from incompatible materials such as strong oxidizing agents.
