Description

Silsesquioxanes, 3-Aminopropyl Me, Ethoxy-Terminated is a functionalized polyhedral oligomeric silsesquioxane (POSS) monomer featuring a reactive aminopropyl group and methoxy/ethoxy terminal units. This hybrid organic-inorganic structure is engineered to act as a versatile nanoscale building block, enabling the precise modification of material properties. It is particularly valuable for industries requiring enhanced thermal stability, mechanical reinforcement, and tailored surface chemistry, such as advanced composites, specialty coatings, and high-performance adhesives.

Application

• Advanced Polymer Composites: Acts as a reactive nanofiller to enhance thermal stability, mechanical strength, and dimensional stability in epoxy, polyimide, and silicone matrices.
• Surface Modification & Coupling Agent: Used to functionalize inorganic surfaces (glass, metals, silica) and improve adhesion between organic polymers and inorganic substrates.
• Specialty Coatings & Resins: Incorporated into formulations to create scratch-resistant, low-k dielectric, or hydrophobic coatings with improved durability.
• Hybrid Material Synthesis: Serves as a precise molecular precursor for constructing organic-inorganic hybrid networks via sol-gel processes.
• Adhesives & Sealants: Improves bonding performance, thermal resistance, and environmental stability in high-demand industrial applications.
• Drug Delivery & Biomedical Materials: Utilized as a functional platform for creating biocompatible carriers or scaffolds with controlled surface properties.

Quality Control

Our production of Silsesquioxanes, 3-Aminopropyl Me, Ethoxy-Terminated adheres to stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including NMR, FT-IR, and HPLC, to verify chemical structure, functional group content, and purity. Certificates of Analysis (COA) documenting all critical parameters are available upon request to ensure full traceability and compliance with your material specifications.

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). Keep the container tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption and degradation.
