Description

n-[3-(Triethoxysilyl)Propyl]-(γ-Lauroylamidopropyl)Triethoxysilane is a specialized organofunctional silane coupling agent that integrates a lauroylamide group into its molecular structure. This unique bifunctional design is critical for enhancing the compatibility and adhesion between inorganic materials and organic polymers, particularly in hydrophobic or non-polar systems. It is essential for formulators and material scientists in the plastics, rubber, and advanced composites industries seeking to improve mechanical properties, moisture resistance, and filler dispersion.

Application

• As a coupling agent and surface modifier for mineral fillers (e.g., silica, clay) in rubber compounds to improve tensile strength and abrasion resistance.
• As a hydrophobizing agent in sealants, adhesives, and coatings to impart enhanced water repellency and durability.
• For the surface treatment of pigments and nanoparticles to improve their dispersion and stability in non-polar polymer matrices like polyolefins.
• As a primer or adhesion promoter on glass, metal, or mineral surfaces to facilitate bonding with organic resins and elastomers.
• In the formulation of reinforced engineering plastics and composites to optimize the interface between fibers and the polymer matrix.
• As a key intermediate in the synthesis of more complex specialty silicone polymers and hybrid materials.

Quality Control

Our production of n-[3-(Triethoxysilyl)Propyl]-(γ-Lauroylamidopropyl)Triethoxysilane adheres to a strict quality management system. Every batch undergoes rigorous analytical testing, including assay by GC or HPLC, identity confirmation (IR, NMR), and impurity profiling, to ensure consistent purity and performance. Certificates of Analysis (COA) documenting all relevant specifications are provided and can be tailored to meet specific customer or application requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent contact with atmospheric moisture, which can lead to hydrolysis and reduced efficacy.
