Description

Trimethoxy(Pentyl)Silane is a versatile organosilicon compound, specifically a functional alkylalkoxysilane. This chemical is valued for its dual functionality, where the pentyl group provides organic compatibility and the methoxy groups offer sites for hydrolysis and condensation reactions. It serves as a critical coupling agent, adhesion promoter, and surface modifier in advanced material formulations. Key industries that utilize this product include specialty coatings, sealants, adhesives, and the manufacturing of silica-based composites and fillers.

Application

• As a coupling agent and adhesion promoter in mineral-filled polymer composites (e.g., filled polyolefins, engineering plastics).
• Surface treatment of inorganic materials like silica, glass fibers, and metal oxides to improve dispersion and interfacial bonding in polymer matrices.
• Key intermediate in the synthesis of more complex silane derivatives and silicone-based polymers.
• Hydrophobic modification agent for surfaces in construction materials and protective coatings.
• Crosslinking agent or co-monomer in moisture-curable silicone sealants and RTV (Room Temperature Vulcanizing) adhesives.
• Used in the formulation of release coatings and primers for industrial applications.

Quality Control

Our Trimethoxy(Pentyl)Silane is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including Gas Chromatography (GC) for purity and identity confirmation, to ensure it meets precise specifications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee batch-to-batch consistency and support your 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). Due to its moisture-sensitive (hygroscopic) nature, containers must be kept tightly sealed to prevent contact with atmospheric moisture, which can lead to hydrolysis and polymerization. Keep away from heat, sparks, and open flame.
