3-Aminopropyltriethoxysilane

Product Overview

3-Aminopropyltriethoxysilane is a premier amino-functional silane coupling agent designed to bridge the interface between organic polymers and inorganic substrates. As a colorless transparent liquid with high chemical purity, this compound exhibits alkaline characteristics and exceptional versatility across multiple industrial sectors. It is specifically engineered to improve adhesion, mechanical strength, and environmental resistance in composite materials, adhesives, and protective coatings. Our manufacturing process ensures consistent quality suitable for demanding applications in glass fiber treatment, mineral filling, and resin modification.

Key Specifications

Industrial Applications

This silane coupling agent is compatible with a wide range of polymer systems including epoxy, phenolic, melamine, nylon, polyvinyl chloride, polyacrylic acid, polyurethane, and various rubber types. In composite manufacturing, it serves as an excellent glass fiber treatment agent, significantly enhancing the mechanical strength, electrical properties, and anti-aging characteristics of the final material. When used in the production of glass fiber wool and mineral wool, it integrates into phenolic resin binders to improve moisture resistance and compression resilience.

For mineral-filled resins such as phenolic, polyester, epoxy, PBT, polyamide, and carbonate systems, this product greatly enhances dry and wet flexural strength, compressive strength, and shear strength. It optimizes the wettability and dispersion of fillers like wollastonite, silica, quartz, aluminum powder, and glass beads within the polymer matrix. Additionally, it functions as a superior adhesion promoter in polyurethane, epoxy, nitrile, and phenolic adhesives, improving pigment dispersion and bonding to metals such as glass, aluminum, and iron.

Performance Benefits
