Description

Siloxanes And Silicones, Di-Me Polymers With 3-Aminopropyl Me 3-(Oxiranylmethoxy)Propyl Silsesquioxanes, Hydroxy-Terminated is a highly functionalized, reactive silicone hybrid polymer that combines the flexibility of polydimethylsiloxane (PDMS) with the robust, cross-linkable functionality of a silsesquioxane cage. This unique structure provides exceptional adhesion promotion, surface modification, and cross-linking capabilities, making it a critical performance additive in advanced material formulations. It is essential for industries requiring materials with enhanced thermal stability, mechanical strength, and compatibility with diverse substrates.

Application

• Advanced Adhesives & Sealants: Acts as a key adhesion promoter and coupling agent in epoxy, polyurethane, and silicone-based formulations for demanding aerospace, automotive, and construction applications.
• High-Performance Coatings: Used to improve surface wetting, adhesion to difficult substrates (metals, glass, plastics), and corrosion resistance in protective and decorative coatings.
• Composite Materials: Serves as a functional additive or sizing agent for glass and carbon fibers to enhance the interfacial bonding and mechanical properties of polymer composites.
• Electronics Encapsulation & Potting: Provides excellent moisture resistance and thermal stability in resins used for protecting sensitive electronic components.
• Specialty Elastomers: Incorporated into silicone rubber formulations to modify cross-link density, improve tear strength, and introduce reactive sites for further functionalization.
• Surface Modification & Release Agents: Utilized to create low-surface-energy, non-stick, or chemically tailored surfaces for industrial and manufacturing processes.

Quality Control

Our production of this advanced functional polymer adheres to strict quality management systems. Each batch is characterized using advanced analytical techniques including GPC, NMR, and FT-IR to confirm structure, functional group content, and molecular weight distribution. Certificates of Analysis (COA) detailing key parameters such as amine value, epoxy equivalent weight, hydroxyl value, and viscosity are provided to ensure consistency and performance for your specific application.

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). Keep container tightly sealed when not in use to prevent moisture absorption and potential premature reaction. Keep away from heat and incompatible materials.
