Description

Siloxanes And Silicones, Di-Me, Ethoxy Me, Ethoxy Ph, Polymers With Me Silsesquioxanes And Ph Silsesquioxanes, Ethoxy-Terminated is a specialized hybrid silicone polymer engineered with a unique combination of methyl, phenyl, and ethoxy-terminated functional groups. This product matters for its ability to impart exceptional thermal stability, hydrophobicity, and compatibility with organic matrices, making it a versatile performance additive. It is primarily needed by formulators in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as in advanced composites and release agents, where enhanced surface properties and durability are critical.

Application

• High-Performance Coatings: Used as an additive to improve water repellency, gloss, scratch resistance, and thermal stability in industrial, automotive, and architectural coatings.
• Specialty Adhesives & Sealants: Enhances flexibility, adhesion to diverse substrates, and environmental resistance in silicone-modified polymers and hybrid formulations.
• Release Agents & Molding: Serves as a key component in non-stick release coatings for plastics, rubber, and composite molding processes.
• Advanced Composites: Acts as a coupling agent or resin modifier to improve interfacial bonding and mechanical properties in fiber-reinforced plastics.
• Electronic Encapsulants: Provides protective, moisture-resistant properties in potting and encapsulation materials for electronic components.
• Personal Care & Cosmetic Ingredients: Utilized in formulations requiring film-forming, conditioning, and water-resistant characteristics.

Quality Control

Our production of this hybrid silicone polymer adheres to strict quality management systems. Each batch undergoes rigorous analytical testing to ensure consistency in functional group content, viscosity, and reactivity. Certificates of Analysis (COA) detailing key parameters 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, 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 and maintain product integrity.
