Description

Siloxanes And Silicones, Di-Me, Hydroxy-Terminated, Reaction Products With Trimethoxymethylsilane And n-3-(Trimethoxysilyl)Propyl-1,2-Ethanediamine is a specialized organosilicon compound engineered as a reactive intermediate and adhesion promoter. This product matters for its unique bifunctional chemistry, combining hydroxy-terminated siloxane flexibility with amine and alkoxysilane reactivity for superior crosslinking and substrate bonding. It is essential for formulators in the coatings, sealants, and advanced composites industries who require enhanced durability, chemical resistance, and adhesion to challenging surfaces.

Application

• Adhesion Promoter: A key component in primers and coupling agents for coatings and adhesives on glass, metals, and plastics.
• Crosslinking Agent: Used in silicone resin and RTV (Room Temperature Vulcanizing) silicone formulations to modify cure profiles and final material properties.
• Surface Modifier: Imparts hydrophobic, release, or specific functional properties to surfaces in textile and fiber treatments.
• Composite Interfacial Agent: Enhances the interfacial bonding between inorganic fillers (e.g., silica, glass fiber) and organic polymer matrices.
• Epoxy & Polyurethane Modifier: Incorporated to improve flexibility, impact resistance, and adhesion of high-performance thermoset systems.
• Waterborne Coating Additive: Functions as a stabilizer and performance enhancer in aqueous coating systems.

Quality Control

Our production of this advanced silicone intermediate adheres to strict quality management systems. Each batch undergoes comprehensive analysis to ensure consistency in reactivity, viscosity, and functional group content. Certificates of Analysis (COA) detailing key parameters are provided to guarantee the material meets your specific formulation requirements and supports your own quality assurance protocols.

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 material is hygroscopic (moisture-sensitive). Keep the container tightly sealed under a dry inert atmosphere (e.g., nitrogen) to prevent moisture absorption and premature reaction. Keep away from heat and incompatible materials.
