Description

Siloxanes and Silicones, di-Me, methoxy Ph, polymers with Ph silsesquioxanes, methoxy-terminated, polymers with adipic acid, diethylene glycol, isophthalic acid, trimethylolethane and trimethylolpropane is a specialized, high-performance hybrid polymer designed for advanced material science applications. This compound matters because it combines the thermal stability and flexibility of silicones with the structural integrity and compatibility of organic polyester/polyol components, creating a unique material platform. It is primarily needed by formulators and manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as for developing high-temperature resistant composites and specialty release agents.

Application

• High-Performance Coatings: Used as a key resin or additive to enhance heat resistance, weatherability, and gloss retention in industrial and protective coatings.
• Specialty Adhesives & Sealants: Serves as a base polymer for formulating adhesives and sealants that require excellent flexibility, adhesion, and durability under extreme temperature cycles.
• Advanced Composite Materials: Acts as a matrix resin or modifier in fiber-reinforced composites for aerospace and automotive applications, improving impact resistance and thermal stability.
• Release Coatings: Formulated into non-stick and easy-release coatings for industrial molding processes, such as in tire manufacturing or plastic molding.
• Elastomer Modification: Employed as a plasticizer or compatibilizer to improve the low-temperature flexibility and processing characteristics of silicone and organic rubber compounds.
• Electronic Encapsulants: Utilized in potting and encapsulation compounds to protect sensitive electronic components from moisture, thermal shock, and mechanical stress.

Quality Control

Our production of this hybrid silicone-polyester polymer adheres to strict quality management protocols. Each batch undergoes rigorous analytical testing to ensure consistency in key parameters such as viscosity, hydroxyl value, and silicone content. Certificates of Analysis (COA) documenting these specifications are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive). Store in a cool, dry, and well-ventilated area at room temperature (15-25°C/59-77°F). Keep the container tightly sealed when not in use to prevent moisture absorption, which can affect product performance.
