Description

2-Propenoic Acid, 2-Methyl-, Polymer With Butyl 2-Propenoate, Chloroethene, Ethenyl Acetate And 2-Propenoic Acid CAS NO 68845-03-4 is a specialized multi-component polymer designed to deliver a balanced profile of adhesion, flexibility, and chemical resistance. This engineered copolymer is critical for formulators seeking to enhance the durability and performance of coatings and adhesives in demanding environments. It is primarily utilized by manufacturers in the industrial coatings, pressure-sensitive adhesives, and sealants sectors.

Application

• Industrial Protective Coatings: Used as a key binder in metal primers and topcoats for machinery, automotive parts, and structural steel, offering excellent corrosion resistance and substrate adhesion.
• Pressure-Sensitive Adhesives (PSAs): Serves as a primary polymer in tapes and labels, providing a strong yet flexible bond with good peel strength and tack.
• Construction Sealants and Caulks: Imparts flexibility, weatherability, and adhesion to concrete, glass, and metal joints in building applications.
• Textile and Non-Woven Binders: Applied as a durable coating or binder for fabrics, providing water resistance and structural integrity.
• Paper and Packaging Coatings: Enhances the surface strength, gloss, and moisture barrier properties of paperboard and packaging materials.
• Specialty Inks: Used in formulations for flexographic and gravure inks to improve adhesion on plastic films and metallic surfaces.

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) are available upon request, detailing key parameters such as solid content, viscosity, glass transition temperature (Tg), and residual monomer levels. We adhere to a cGMP compliant quality management system to ensure batch-to-batch consistency and reliability for your formulations.

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). Keep away from heat sources and open flame. For long-term storage, ensure containers are sealed to prevent skin formation or moisture absorption.
