Description

2-Propenoic Acid, 2-Methyl-, Butyl Ester, Polymer With Butyl 2-Propenoate, Methyl 2-Methyl-2-Propenoate And 2-Propenoic Acid is a high-performance acrylic copolymer designed to deliver exceptional durability and versatility in demanding formulations. This multi-monomer polymer offers a balanced profile of chemical resistance, adhesion, and film-forming properties critical for industrial applications. It is essential for manufacturers in the coatings, adhesives, and sealants industries seeking to enhance product performance and longevity.

Application

• Industrial and Protective Coatings: Used as a key binder in metal primers, automotive topcoats, and corrosion-resistant paints for machinery and structural steel.
• Adhesives and Sealants: Provides strong adhesion and flexibility in pressure-sensitive adhesives (PSAs), construction sealants, and assembly bonding agents.
• Textile and Leather Finishes: Serves as a durable coating and finishing agent to improve water repellency, abrasion resistance, and handle of fabrics and leather goods.
• Printing Inks: Formulated into overprint varnishes and ink vehicles to enhance gloss, rub resistance, and drying characteristics.
• Plastic Modifiers: Acts as an impact modifier or processing aid to improve the toughness and surface characteristics of various plastic compounds.

Quality Control

Our acrylic copolymer is manufactured under a strict quality management system to ensure batch-to-batch consistency and performance reliability. Each lot is tested against stringent internal specifications for critical parameters such as solids content, viscosity, acid value, and glass transition temperature (Tg). Certificates of Analysis (COA) documenting these results are 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 and 77°F). Avoid exposure to extreme heat or freezing conditions to maintain product stability and prevent phase separation.
