Description

2-Propenoic acid, 2-methyl-, polymer with butyl 2-methyl-2-propenoate, butyl 2-propenoate, ethenylbenzene, methyl 2-methyl-2-propenoate and 1,2-propenoate is a high-performance, multi-component acrylic copolymer designed for demanding industrial applications. This polymer offers a unique balance of properties derived from its specific monomer composition, including excellent film formation, adhesion, and chemical resistance. It is a critical raw material for formulators in the coatings, adhesives, and specialty chemical industries seeking to enhance product durability and performance.

Application

• Industrial and Protective Coatings: Used as a key resin binder in high-durability paints, metal coatings, and corrosion-resistant finishes.
• Adhesives and Sealants: Serves as a primary polymer component in pressure-sensitive adhesives (PSAs), construction sealants, and industrial bonding agents.
• Textile and Leather Finishes: Employed in coatings and backings to provide water resistance, flexibility, and improved handle.
• Paper and Packaging Coatings: Enhances surface gloss, printability, and barrier properties in specialty paper and cardboard applications.
• Automotive Refinish: A component in primer and topcoat formulations requiring excellent adhesion and environmental resistance.
• Inks and Overprint Varnishes: Contributes to the formulation of fast-drying, scratch-resistant printing inks and protective varnishes.

Quality Control

Our production of this acrylic copolymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as molecular weight distribution, glass transition temperature (Tg), viscosity, solids content, and residual monomers are rigorously controlled. Certificates of Analysis (COA) documenting full specifications are provided with each shipment to support your quality assurance protocols.

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 sources and open flame. For long-term storage, an inert atmosphere is recommended to maintain polymer stability.
