Description

(1-(3-Triethoxysilyl)Propyl)-2,2-Diethoxy-1-Aza-2-Silacyclopentane, Tech-90 is a specialized organosilicon compound, specifically a bifunctional silane coupling agent containing both alkoxysilyl and aza-silacyclopentane functional groups. This unique structure provides dual reactivity, enabling it to act as a powerful adhesion promoter and surface modifier between inorganic substrates and organic polymers. It is essential for manufacturers seeking to enhance the mechanical properties, durability, and environmental resistance of composite materials. Key industries that rely on this advanced silane include advanced composites, specialty adhesives and sealants, and high-performance coatings.

Application

• Adhesion Promoter for Composites: Enhances the bond between glass, mineral, or metal fibers and polymer matrices (e.g., epoxy, polyurethane, nylon), significantly improving interlaminar shear strength and moisture resistance.
• Surface Modification of Fillers: Used to treat silica, alumina, and other inorganic fillers to improve their dispersion and compatibility in plastic and rubber compounds, reducing viscosity and enhancing mechanical properties.
• Primer for Adhesives & Sealants: Applied as a primer on glass, metal, or concrete surfaces to dramatically improve the adhesion and water resistance of subsequently applied silicone, polyurethane, or MS polymer sealants.
• Crosslinking Agent/Co-monomer: Incorporated into polymer backbones (e.g., in silicone hybrids or organic polymers) to introduce reactive sites or improve thermal and chemical stability.
• Corrosion-Resistant Coatings: Formulated into pretreatment layers or coating systems for metals (aluminum, steel) to provide superior protection against corrosion and environmental weathering.
• Fiber Sizing: A key component in sizing formulations for fiberglass and carbon fibers to protect filaments and ensure optimal matrix adhesion during composite manufacturing.

Quality Control

Our Tech-90 grade of this silane coupling agent is produced under strict quality management protocols to ensure batch-to-batch consistency and performance reliability. Each lot undergoes rigorous analytical testing, including assay by GC or titration and impurity profiling. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and key physical parameters is provided with every shipment to support your quality assurance and regulatory needs.

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). Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed after opening to prevent hydrolysis and degradation from atmospheric moisture. Keep away from strong acids and bases.
