Description

2-Propenoic Acid, 2-Methyl-, Methyl Ester, Polymer With 1,1-Dichloroethene is a high-performance copolymer of methyl methacrylate (MMA) and vinylidene chloride (VDC). This material is engineered to deliver an exceptional balance of barrier properties, chemical resistance, and optical clarity. It is a critical raw material for formulators and manufacturers requiring durable, protective coatings and films. The product, identified by CAS No. 25120-29-0, serves advanced applications in packaging, specialty paints, and industrial finishes.

Application

• High-Barrier Packaging Coatings: Used as a key resin for food, pharmaceutical, and technical packaging films to provide superior oxygen and moisture barrier properties.
• Protective Industrial Coatings: Formulated into corrosion-resistant and chemical-resistant paints for metal, concrete, and plastic substrates in harsh environments.
• Adhesive and Sealant Formulations: Serves as a base polymer to enhance the adhesion, cohesion, and durability of high-performance adhesives and sealants.
• Specialty Inks and Overprint Varnishes: Imparts gloss, scratch resistance, and weatherability to inks and protective varnishes for printed materials.
• Fiber and Textile Finishes: Applied as a coating or binder to improve the water repellency, stain resistance, and feel of technical textiles and non-wovens.
• Automotive and Transportation Finishes: Used in primer and topcoat formulations for components requiring excellent gloss retention and resistance to fuels and cleaners.
