Description

Siloxanes And Silicones, Di-Me, [[Dimethoxy[3-[[3-(Trimethoxysilyl) Propyl]Amino]Propyl]Silyl]Oxy]-Terminated is a specialized organofunctional silane-terminated siloxane, engineered to act as a high-performance coupling agent and adhesion promoter. This compound is critical for enhancing the compatibility and bonding strength between organic polymers and inorganic substrates. It is essential for manufacturers in the adhesives, sealants, coatings, and composite materials industries who require superior surface modification and durable material interfaces.

Application

• Adhesion Promoter in epoxy, polyurethane, and silicone-based adhesives and sealants for glass, metal, and mineral surfaces.
• Surface Modifier/Coupling Agent for silica, glass fibers, and other fillers to improve dispersion and interfacial bonding in polymer composites.
• Primer/Crosslinker in protective and decorative coatings to enhance corrosion resistance, weather durability, and substrate adhesion.
• Reinforcement Agent in rubber and elastomer formulations to improve mechanical properties and thermal stability.
• Waterproofing Additive in construction materials and textile treatments due to its hydrophobic properties.
• Intermediate for the synthesis of more complex silicone polymers and hybrid organic-inorganic materials.

Quality Control

Our production of this silane-terminated siloxane adheres to strict quality management systems. Every batch is characterized using advanced analytical techniques including FT-IR, NMR, and GPC to confirm structure, molecular weight distribution, and functional group content. Certificates of Analysis (COA) detailing purity, viscosity, amine value, and moisture content are provided to ensure traceability and compliance with your formulation requirements.

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 the container tightly sealed under a dry inert atmosphere (e.g., nitrogen) to prevent hydrolysis and maintain shelf life.
