Description

Polyethyleneglycol Bisphenol A Epichlorohydrin Copolymer 15,000-20,000 Da is a high molecular weight, non-ionic polymeric surfactant and resin modifier derived from bisphenol A, epichlorohydrin, and polyethylene glycol. This copolymer is valued for its unique combination of hydrophilicity, flexibility, and structural integrity, making it an essential performance additive. It is primarily used in industries requiring advanced material properties, such as specialty coatings, adhesives, and pharmaceutical formulations, where it acts as a dispersant, viscosity modifier, or compatibilizer.

Application

• Specialty Coatings & Inks: Used as a rheology modifier and dispersing agent to improve flow, leveling, and pigment stability in high-performance industrial and automotive coatings.
• Adhesives & Sealants: Functions as a flexibilizer and tackifier, enhancing adhesion strength and elasticity in epoxy and polyurethane-based systems.
• Pharmaceutical Excipients: Employed as a matrix former or release modifier in controlled-release tablet and capsule formulations.
• Electronic Materials: Serves as a component in photoresists, encapsulants, and dielectric materials for its thermal stability and film-forming properties.
• Textile & Fiber Processing: Acts as a lubricant and antistatic agent during fiber spinning and finishing processes.
• Personal Care Products: Utilized as a film-forming agent and emulsifier in hair styling gels, creams, and lotions.

Quality Control

Our Polyethyleneglycol Bisphenol A Epichlorohydrin Copolymer is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent molecular weight distribution, purity, and performance characteristics. Certificates of Analysis (COA) documenting key parameters such as assay, viscosity, and residual solvents are available upon request. We can support compliance with relevant standards for industrial and pharmaceutical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); keep the container tightly sealed to prevent absorption of atmospheric moisture.
