Description

1,3-Isobenzofurandione, Polymer With 2,5-Furandione And 2,2-Oxybisethanol CAS NO 26123-45-5 is a specialized polymeric material derived from phthalic anhydride, maleic anhydride, and diethylene glycol. This compound is valued for its unique chemical structure, which imparts properties suitable for advanced material synthesis. It is primarily sought by manufacturers in the coatings, adhesives, and specialty polymer industries seeking to modify resin characteristics such as flexibility, adhesion, and chemical resistance.

Application

• Polymer Modifier: Used as a reactive intermediate or additive to enhance the flexibility, adhesion, and durability of alkyd, polyester, and polyurethane resins.
• Industrial Coatings: Serves as a key component in the formulation of high-performance protective coatings for metal, wood, and plastic substrates.
• Adhesives & Sealants: Incorporated to improve the bonding strength and environmental resistance of structural and specialty adhesives.
• Composite Materials: Acts as a compatibilizer or cross-linking agent in fiber-reinforced plastics and other composite systems.
• Electrical Insulation: Utilized in the production of insulating varnishes and encapsulants for electronic components.
• Textile & Leather Auxiliaries: Functions as a finishing agent to provide water repellency, softness, or other desired surface properties.

Quality Control

Our production of 1,3-Isobenzofurandione, Polymer With 2,5-Furandione And 2,2-Oxybisethanol adheres to stringent quality management protocols. Each batch is characterized for critical parameters including acid value, hydroxyl value, viscosity, and color to ensure consistency and performance. 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). This material is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product properties.
