Aminopropylmethyldiethoxysilane

Aminopropylmethyldiethoxysilane (CAS 3179-76-8 ) is an aminofunctional silane coupling agent that bridges inorganic substrates and organic polymer matrices. It bonds chemically to both surfaces, improving adhesion, durability, and interfacial compatibility across a range of industrial systems. In adhesives, sealants, and coatings, it functions as a primer or additive to improve adhesion to glass, metals, and mineral fillers. This is particularly useful in automotive and construction assemblies exposed to moisture. Electronics manufacturers use it to treat substrates and encapsulants, where reliable adhesion under thermal cycling is critical to component longevity. It ensures that sensitive electronic parts remain protected and functional over time. In filled rubber and polymer compounding, it improves filler dispersion and crosslink density, directly affecting mechanical performance of the finished part. This leads to stronger materials with better resistance to environmental stressors. Personal care formulators incorporate aminofunctional silanes into hair treatment systems to modify surface wetting and improve substantivity on damaged fiber. This application helps in creating more effective and long-lasting cosmetic products. Aminopropylmethyldiethoxysilane is supplied as a clear liquid in standard packaging ranging from drums to IBC containers. Technical grade is the primary commercial form, with purity specifications typically at 97% or higher. Bulk quantities are available for industrial users, with smaller quantities offered for formulation and R&D applications. This flexibility allows for both large-scale manufacturing and specialized laboratory testing needs. Contact us for supply of Aminopropylmethyldiethoxysilane Request Quote
