Import 3-Aminopropyltrimethoxysilane — Buy in Bulk from Supplier in South Africa

3-Aminopropyltrimethoxysilane is a methoxy-functional amino silane with the molecular formula C6H17NO3Si and a molecular weight of 179.3 g/mol. Supplied by Akaba B2B Trading from South Africa, this coupling agent features a higher hydrolysis rate than its ethoxy analogues, making it suitable for applications requiring rapid bonding. It is a colourless to straw-coloured liquid with a boiling point of approximately 205°C and a purity level of 98% or higher.

The trimethoxy groups in this silane hydrolyse more quickly than triethoxy groups, which can be advantageous in fast-curing systems but may require careful control of moisture exposure during processing. Typical amino content for this class is 7-9%, and the methoxy groups provide good compatibility with polar resins such as epoxies and polyamides. Standard applications include improving the adhesion of coatings to glass, metals, and mineral substrates, as well as enhancing the mechanical properties of fibre-reinforced composites.

This silane is commonly used in the automotive, aerospace, and electronics industries for high-performance adhesives, sealants, and coatings. It is particularly effective in environments where moisture resistance and thermal stability are critical. Buyers typically source it in 25L, 200L, or 1000L containers, depending on production scale. Confirm the supplier’s ability to provide consistent batch quality, as variations in purity or hydrolysis rate can impact performance in demanding applications.
