What is Aminopropylmethyldiethoxysilane?
An aminofunctional silane coupling agent (CAS 3179-76-8) that bridges inorganic substrates and organic polymer matrices.
Where is Aminopropylmethyldiethoxysilane used?
- Adhesives, sealants and coatings: primer or additive improving adhesion to glass, metals and mineral fillers
- Automotive and construction assemblies exposed to moisture
- Electronics: substrate and encapsulant treatment for adhesion under thermal cycling
- Filled rubber and polymer compounding: improved filler dispersion and crosslink density
- Hair treatment systems: modifies surface wetting and substantivity on damaged fiber
- It bonds chemically to both surfaces, improving adhesion, durability and interfacial compatibility.
Commercial specifications
- Technical grade, purity typically 97% or higher
- Packaging from drums to IBC containers
- Bulk quantities and smaller quantities for formulation and R&D
