Description

2-Propenoic Acid, 2-Methyl-, Methyl Ester, Polymer With Butyl 2-Propenoate, Dihydro-3-Methylene-2,5-Furandione And Ethenylbenzene CAS NO 116889-76-0 is a specialized multi-component polymer designed to deliver enhanced performance characteristics in demanding coating and adhesive formulations. This engineered copolymer is valued for its ability to provide an optimal balance of durability, adhesion, and chemical resistance. It is primarily sought after by manufacturers in the industrial coatings, pressure-sensitive adhesives, and specialty sealants sectors who require high-performance, tailored polymeric solutions.

Application

• Industrial and Protective Coatings: Used as a key film-forming resin to enhance weatherability, corrosion resistance, and mechanical strength in metal and concrete coatings.
• Pressure-Sensitive Adhesives (PSAs): Serves as a primary polymer backbone to provide excellent tack, peel adhesion, and cohesive strength for labels, tapes, and graphic films.
• Architectural Paints: Imparts superior scrub resistance, stain resistance, and durability in high-performance interior and exterior paint formulations.
• Specialty Sealants and Caulks: Provides flexibility, adhesion to diverse substrates, and long-term durability in construction and automotive sealant applications.
• Printing Inks: Used as a binder to improve pigment dispersion, gloss, and adhesion on various printing substrates.
• Textile and Leather Finishes: Applied as a coating to enhance the water repellency, abrasion resistance, and handle of fabrics and leather goods.

Quality Control

Our production of this advanced copolymer adheres to strict quality management systems, ensuring batch-to-batch consistency and performance reliability. Each lot is characterized for critical parameters including monomer conversion, molecular weight distribution, glass transition temperature (Tg), and solution viscosity. Certificates of Analysis (COA) detailing these specifications are provided with every shipment. We support compliance with relevant global regulatory frameworks for industrial chemicals.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (typically 15-25°C). Keep away from heat sources and open flame. For long-term storage, consider under an inert atmosphere to prevent oxidation. Ensure containers are kept tightly sealed to prevent moisture absorption and skin formation.
