Description

2-Propenoic Acid, 2-Methyl-, Butyl Ester, Polymer With Dodecyl 2-Methyl-2-Propenoate, Ethenylbenzene And Oxiranylmethyl 2-Methyl-2-Propenoate is a specialized acrylic copolymer designed for high-performance applications. This multi-component polymer offers a unique balance of properties derived from its constituent monomers, including flexibility, adhesion, and chemical resistance. It is primarily utilized in the formulation of advanced industrial coatings, adhesives, and sealants where durability and specific functional characteristics are required.

Application

• Industrial and Protective Coatings: Used as a key resin binder in high-performance coatings for metal, plastic, and wood substrates, providing excellent weatherability and chemical resistance.
• Adhesive Formulations: Serves as a base polymer in pressure-sensitive adhesives (PSAs) and structural adhesives, contributing to tack, peel strength, and cohesion.
• Automotive Finishes: Employed in primer, basecoat, and clearcoat systems for automotive OEM and refinish applications due to its durability and gloss retention.
• Can and Coil Coatings: A critical component in coatings for food packaging (can linings) and pre-coated metal coils, offering necessary flexibility and barrier properties.
• UV-Curable Systems: The oxiranylmethyl (glycidyl) methacrylate component can facilitate cross-linking in radiation-curable coatings and inks for fast curing and high performance.
• Specialty Inks: Used in the formulation of printing inks for plastics and metals, enhancing adhesion and rub resistance.

Quality Control

Our production of this acrylic copolymer adheres to stringent quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as monomer residue, molecular weight distribution, viscosity, solids content, and epoxy equivalent weight (for the glycidyl functionality) are rigorously monitored. Certificates of Analysis (COA) documenting these specifications 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). Keep away from heat sources and open flame. For long-term storage under warm conditions, monitoring for viscosity stability is recommended.
