Description

2-Propenoic Acid, 2-Methyl-, Butyl Ester, Polymer With Methyl 2-Methyl-2-Propenoate, 2-Methylpropyl 2-Methyl-2-Propenoate And 2-Sulfoethyl 2-Methyl-2-Propenoate is a specialized acrylic copolymer designed to deliver enhanced performance characteristics. This multi-monomer polymer is engineered to provide a unique balance of adhesion, flexibility, and water solubility, making it a critical component in advanced formulations. It is primarily utilized in industries requiring high-performance film-forming agents and binders with specific rheological and surface-active properties.

Application

• Pressure-Sensitive Adhesives (PSAs): Used as a key binder to provide tack, peel strength, and cohesive balance in label and tape formulations.
• Water-Based Inks and Coatings: Acts as a film-forming resin, offering excellent pigment binding, gloss, and substrate adhesion for paper, plastic, and metal coatings.
• Textile Finishing and Nonwovens: Serves as a durable binder for fiber bonding, providing softness, wash resistance, and dimensional stability.
• Leather Finishing: Imparts flexibility, scuff resistance, and a uniform finish to leather surfaces.
• Hair Styling and Personal Care Products: Functions as a film-forming polymer in gels and sprays, providing hold and humidity resistance.
• Construction Chemicals: Used as an additive in cementitious coatings and tile adhesives to improve workability, adhesion, and water retention.

Quality Control

Our production of this acrylic copolymer adheres to stringent quality management protocols to ensure batch-to-batch consistency and performance reliability. Each lot is characterized for critical parameters including solid content, viscosity, pH, glass transition temperature (Tg), and acid value. Comprehensive Certificates of Analysis (COA) detailing these specifications are provided with every shipment. Our quality system is designed to support compliance with relevant global regulatory frameworks for industrial and specialty chemical applications.

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). This product is hygroscopic (moisture-sensitive). Prolonged exposure to high humidity or extreme temperatures should be avoided to prevent changes in viscosity or performance. Keep away from incompatible materials such as strong oxidizing agents.
