Description

Butanoic Acid, 3-Oxo-, 2-Propenyl Ester, Polymer With Butyl 2-Propenoate, Methyl 2-Methyl-2-Propenoate, 2-Methyl-2-Propenoic Acid And 2-Propenoic Acid is a specialized acrylic copolymer designed to deliver high-performance characteristics in demanding formulations. This multi-monomer polymer is engineered to provide an optimal balance of film-forming properties, adhesion, and chemical resistance, making it a critical component for advanced industrial coatings and adhesives. It is essential for manufacturers in the paints & coatings, pressure-sensitive adhesives, and specialty polymer industries seeking to enhance product durability and functionality.

Application

• Industrial and Protective Coatings: Used as a key resin binder in high-performance metal, wood, and plastic coatings requiring excellent weatherability and chemical resistance.
• Pressure-Sensitive Adhesives (PSAs): Serves as a primary polymer for labels, tapes, and graphic films, offering tunable tack, peel strength, and holding power.
• Printing Inks: Functions as a vehicle resin in flexographic and gravure inks, providing good pigment wetting, gloss, and adhesion to various substrates.
• Textile and Leather Finishes: Employed in coatings and binders to impart water repellency, flexibility, and abrasion resistance to fabrics and leather goods.
• Construction Materials: Incorporated into sealants, caulks, and concrete modifiers to improve elasticity, adhesion, and durability.
• Specialty Polymer Modifications: Acts as an additive or compatibilizer to enhance the properties of other polymer systems, such as impact strength or surface characteristics.

Quality Control

Our production of this acrylic copolymer adheres to stringent quality management systems to ensure batch-to-batch consistency and performance reliability. Each lot undergoes comprehensive testing for critical parameters including solids content, viscosity, acid value, and glass transition temperature (Tg). Certificates of Analysis (COA) documenting these specifications are available upon request, supporting your quality assurance and regulatory compliance needs.

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 changes in viscosity.
