Description

2-Propenoic Acid, 2-Methyl-, Butyl Ester, Polymer With Dodecyl 2-Methyl-2-Propenoate And Octadecyl 2-Methyl-2-Propenoate is a high-performance, multi-component acrylic copolymer designed for advanced material formulations. This polymer is engineered to deliver a unique balance of properties, including excellent film formation, durability, and compatibility with various substrates and additives. It serves as a critical raw material for industrial manufacturers seeking to enhance the performance of their coatings, adhesives, and sealants.

Application

• Industrial and Protective Coatings: Used as a key film-forming agent in solvent-based and high-solids coatings for metal, wood, and plastic substrates, providing corrosion resistance and weatherability.
• Pressure-Sensitive Adhesives (PSAs): Imparts tack, peel strength, and cohesive strength in adhesive tapes and labels.
• Construction Sealants and Caulks: Enhances flexibility, adhesion, and long-term durability in elastomeric sealants for joints and gaps.
• Printing Inks: Serves as a resin component in specialty inks, improving gloss, rub resistance, and substrate adhesion.
• Textile and Leather Finishes: Applied as a coating to provide water repellency, softness, and abrasion resistance to fabrics and leather goods.
• Plastic Modifiers: Used as an impact modifier or processing aid to improve the toughness and surface characteristics of thermoplastic compounds.

Quality Control

Our production of this acrylic copolymer adheres to strict quality management systems, ensuring batch-to-batch consistency for your formulations. Key parameters such as molecular weight distribution, monomer residue, viscosity, and glass transition temperature (Tg) are rigorously monitored. A comprehensive Certificate of Analysis (COA) detailing all relevant specifications is provided with each shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from heat, sparks, and open flame. Ensure containers are kept tightly sealed when not in use to prevent skinning or changes in viscosity.
