Description

Siloxanes And Silicones, Di-Me, Polymers With 3-(2-Aminoethyl)Aminopropyl Silsesquioxanes, Hydroxy-Terminated is a specialized functionalized silicone polymer that combines the flexibility and thermal stability of polydimethylsiloxane (PDMS) with the reactivity of amino and hydroxy groups. This unique dual-functional chemistry makes it a critical component for creating high-performance, cross-linked networks and surface modifications. It is essential for formulators and manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking to enhance material properties like adhesion, compatibility, and mechanical strength.

Application

• Adhesion Promoter: Used as a coupling agent in epoxy, polyurethane, and silicone-based adhesives and sealants to improve bonding to difficult substrates like metals, glass, and plastics.
• Surface Modification Agent: Imparts hydrophilic or reactive surface properties to inorganic fillers (e.g., silica, glass fibers) and pigments for better dispersion in polymer matrices.
• Cross-linking Agent/Chain Extender: Functions as a reactive intermediate in the synthesis of modified silicones, polyurethanes, and epoxy resins, contributing to tailored mechanical and thermal properties.
• Coating Additive: Enhances the scratch resistance, weatherability, and surface slip of industrial and protective coatings.
• Release Coating Intermediate: Serves as a key component in formulating cured silicone release liners for pressure-sensitive adhesives.
• Fiber Treatment: Applied to textiles and fibers to provide softness, durability, and water repellency with improved handle.

Quality Control

Our production of this functional silicone polymer adheres to strict quality management systems. Each batch is characterized for critical parameters including amine value, hydroxy content, viscosity, and molecular weight distribution to ensure consistent performance. Certificates of Analysis (COA) detailing these specifications are provided and available upon request, supporting compliance in regulated formulation environments.

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/59-77°F). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect reactivity and performance.
