Description

2-Butenedioic acid (2E)-, dibutyl ester, polymer with ethenylbenzene, 2-hydroxyethyl 2-methyl-2-propenoate, methyl 2-methyl-2-propenoate and 2-methyl-2-propenoic acid CAS NO 118270-86-3 is a specialized multi-component polymer designed to deliver specific performance characteristics in advanced coating and adhesive formulations. This engineered copolymer is valued for its ability to enhance film formation, adhesion, and durability across diverse substrates. It is primarily sought by manufacturers in the industrial coatings, specialty adhesives, and polymer modification sectors seeking to improve product performance and reliability.

Application

• Industrial and Protective Coatings: Used as a key resin component to improve gloss, chemical resistance, and weatherability in metal, wood, and plastic coatings.
• High-Performance Adhesives: Enhances tack, peel strength, and cohesive strength in pressure-sensitive and structural adhesive formulations.
• Polymer Modification: Acts as an impact modifier or compatibilizer to improve the toughness and processing characteristics of other polymer systems.
• Printing Inks: Incorporated into ink vehicles to promote adhesion, rub resistance, and color development on non-porous surfaces.
• Sealants and Caulks: Provides flexibility, adhesion, and durability in construction and automotive sealant applications.
• Textile and Leather Finishes: Used in coatings to impart water repellency, abrasion resistance, and a soft hand feel.

Quality Control

Our production of this specialty copolymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as monomer conversion, molecular weight distribution, acid value, and glass transition temperature (Tg) are monitored. Certificates of Analysis (COA) detailing specific lot specifications are available upon request 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 room temperature (15-25°C). Keep away from heat sources and open flames. For long-term storage, consider using under an inert atmosphere to prevent oxidation or moisture uptake, which could affect polymer properties.
