Description

Maleic Anhydride, Polymer With 1,3-Butanediol And 2,2'-[(1-Methyl Ethylidene)Bis(4,1-Phenyleneoxy)]Bis Ethanol is a specialized polymeric resin derived from maleic anhydride, a bifunctional monomer, and a blend of diols. This compound is engineered to provide enhanced thermal stability, chemical resistance, and tailored reactivity, making it a critical intermediate for high-performance materials. It is primarily needed by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as for advanced composite and electronic applications.

Application

• High-Performance Coatings: As a key resin component in powder coatings, industrial finishes, and can coatings requiring excellent durability and adhesion.
• Advanced Adhesives & Sealants: Used to formulate structural adhesives and high-temperature sealants with superior bonding strength and flexibility.
• Engineering Thermoplastics & Composites: Serves as a modifier or cross-linking agent to enhance the mechanical and thermal properties of composite materials.
• Electronic Encapsulants: Employed in potting compounds and encapsulants for electronic components due to its good electrical insulation and thermal resistance.
• Ink Resins: A functional polymer in specialty printing inks, contributing to film hardness, gloss, and substrate adhesion.
• Polymer Modification: Used to introduce carboxyl functionality or improve compatibility in polymer blends and alloys.

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards and batch-to-batch consistency. Quality is monitored through parameters such as acid value, hydroxyl value, viscosity, and glass transition temperature (Tg). Certificates of Analysis (COA) documenting these specifications are available upon request. Our manufacturing processes adhere to ISO 9001 quality management principles.

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). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent absorption of atmospheric moisture which can affect product performance.
